Distinctly British thumb planes were never produced in quantity; chariot planes were the most similar British plane in design and function, but chariots were made in greater quantities by a larger number of planemakers.  Both chariot and thumb planes had thick bevel up irons on a wooden infill bed, around 20 degrees, with a 3 to 5 inch body respectively, and easily used with one hand.  Given these similarities, the relative popularity of the 19th century chariot plane almost eclipsed the thumb plane. Certainly, some 19th century woodworkers preferred using the bullnose feature for planing in tight spots.  A majority of British chariot planes had the bullnose component: with the mouth placed close to the toe.

Since so few British planemakers made thumb planes, examples are difficult to find.  This lack of antique English thumb planes has created demand, so a number of current planemakers are producing new thumb planes.  Interest in thumb planes today quite possibly equals that of the 19th and 20th centuries.



Scottish Chariot Planes:

Scottish style chariots, from the mid-19th century, with their mouth 1/3rd of the way back from the toe, could have provided inspiration for early makers of the thumb plane.

Scottish chariot planes are characterized by having a stepped toe, front infill, flat heel, and a mouth placed 1/3rd of the way back from the toe.  The iron, is usually around 1 1/4″ wide, bevel up, over a rosewood bed.

Length ranges from 4 1/2″ to 5 1/2″, proportions that were mirrored in the English thumb planes.  Some examples are very high quality.

James Claussen’s Scottish Chariot plane is one of the finer examples of this type of plane, with a small tote, and a nice half-round bridge in gunmetal.  Scottish Chariot planes are scarce, and it is evident that these were personalized by their user/owners, in contrast to production type planes.





Years of the Thumb Planes

Working in the early to mid-19th century, George Kerr (born in Aberdeen, Scotland 1805) may have been the first innovator of thumb planes, and Stewart Spiers likely commenced making them around that same time or a few years later.  John Holland also made thumb planes and his working years were 1858 to 1907.  The last historical manufacturer of the thumb plane was Thomas Norris & Son (late 19th century to ~1942), and Norris made more of this type than anyone else in the trade. Thomas Norris (1836-1906) was located at 57 York St, (in Lambeth, London) and John Holland (1831-1912) worked out of 93 York Rd., and they were there concurrently between 1870 and 1890.  It would have allowed plenty of time for an exchange of ideas between these two planemakers.

American Block Planes:

American block planes were the closest domestic equivalent to the English thumb plane, but their general introduction circa 1872 postdated the thumb planes by at least 20 years.  Birdsill Holly of Seneca, New York did produce a ‘block plane’ in the 1850s, but very few were made, nowhere near the economies of scale that typically exemplified American industrial production.  At 7 3/4″  long with a 1 3/4″ iron, the Holly block plane was close to the size of a mitre plane.  English influence from the thumb plane on Leonard Bailey was apparent in the side profile of his Excelsior pattern block plane.

Bailey Victor adjustable block plane.

Bailey’s block plane was the American version of a small plane, with a bevel up iron, set at a low ~20 degree angle.  Block planes were used for end grain, but also for a myriad of general handyman tasks.  –A tool for the masses.  English thumb planes would more often be found in a cabinet or instrument makers’ toolkit, and used for critical detailed work.


In contrast to the British thumb planes, the Bailey/Stanley block planes caught on like wildfire, and were made in prolific quantities and variations from the 1870s until World War Two.  On average, American block planes ranged from 6 to 7 inches long, compared with British thumb planes, generally around 5 inches long.  While similarities existed between these two types, differences were also present: thumb planes had a much thicker iron on a wooden infill bed, and they were largely a handmade product.  American block planes were mass produced: much less expensive, in many cases adjustable, and had a thinner iron bedded on the iron casting.

Some five inch American block planes:

Instrument makers had little choice for a plane in the 5 inch class in the late 19th and early 20th centuries. These small block planes were used for such tasks as making guitar fingerboards, stringed instrument bows, and paring down gussets on repaired piano keysticks. C. H. Lang included the Stanley no. 102 block plane in his 1905 piano supply catalogue.

From the sublime to the pedestrian: Stanley no. 102 small block plane (c. 1936-1950).

Stanley 102 plane, early catalogue excerpt (c.1884-1887).





Many English variants of the 102 type were made by Record, Hobbies, and Stanley U.K.



Stanley No. 203 5 1/2″ block plane, circa early 1950s. Rosewood knob.


Stanley’s No. 203 plane had a casting that was only 5 1/2″ long, but because of the fittings on it, it takes up more space than the other 5″ planes shown here.  The rosewood knob is oversized, the cam lock lever cap is large, and the adjustment knob extends out the back.  Additionally, it looks to actually have a bedding angle slightly higher than 20 degrees.  Taking that into account, it is a quality plane, with a convenient handy-grip feature, and an effective Traut iron adjuster.



Mathiesen Thumb Planes

Mathieson 1899 Price List, including Thumb planes.

Mathieson dovetailed Thumb planes with 1 1/4″ irons at 11/6, were the same price in 1899 as later Norris Thumb planes at 11/6 in 1908.  At 11/- , in 1909, Spiers No. 9 Thumb planes were less expensive, and in Norris’ 1914 catalogue, prices for their Nos. 31 and 32 Thumb planes were reduced to 11/-. and 10/6 respectively.

Mathieson No. 854 thumb plane, as illustrated in their 1899 catalogue. Profile was weighted towards the closed heel, and appeared much like a Norris no. 12 dovetailed thumb plane.

The interesting and highly valuated Mathieson thumb plane sold in the November 2019 Brown Tool Auction for $4,746.00 (before commission).  We are unlikely to see another one come to market anytime soon.  Noted collector, George Anderson, wrote that the thumb plane, in general, was the most challenging of all the British infill planes to collect.

Buck/Spiers Thumb Planes

Planemaker Konrad Sauer’s description of a Spiers no. 9 thumb plane in 2013:

[The Spiers no. 9 thumb plane] was a pretty amazing experience.  Everything was exactly where it needed to be.  There was an amazing relationship between the sneck of the iron, the top of the lever cap screw and the empty area at the front of the plane.  There was a complex and deliberate relationship between these points and they all worked together to provide a very comfortable experience.  I was pretty shocked and was once again reminded that simple looking, does not mean that complex design thought did not go into something.  I kept this experience tucked away until the time was right.

Octagonal lever cap screws were featured on a relatively small number of early British metal planes dating from the late 1840s to the early 1860s.  Planemakers who utilized the octagonal screw included George Kerr, Robert Towell, Edward Cox, and of course, Stewart Spiers.

Looks like an original owner of this Buck Thumb plane tapped on the lever cap to adjust the iron.  I imagine something like this being done towards the end of a long day of work under sub-optimal conditions.

Two different versions of the Spiers no. 9 thumb plane below.  Example on the left seems older, with a longer lever cap, and similar to screw sided models.  But this type was photographed for the 1908 catalogue.  Plane on the right seems later, with features copied by Norris.  Similar examples have shown up with Buck 247 Tottenham Ct. Rd. (1867-1879), however.

In the 1908 Spiers’ catalogue, the no. 9 thumb plane was not in production and only made upon special order.  Possibly, this was an image of an older plane that happened to be handy when the catalogue was put together.


Buck/Norris Thumb Planes

Norris No. 12 Dovetailed Thumb Plane, in Norris’ c. 1908 Catalogue.

Thomas Norris’ first thumb planes were dovetailed and were classified as No. 12.  These were not produced in any quantity, but some of them were rebadged as Buck thumb planes.  While the dovetails are not visible in this image, the iron shows a nib, which was not present in the 1914 and 1928 catalogues.  Norris’ No. 31 Thumb plane, in the 1928 catalogue, did show a rebate style sneck on both sides of the iron.



Thumb planes, as offered in J. Buck’s 1912 Pianomakers’ Tool Catalogue.

J. Buck 1912 Catalogue: Norris Thumb planes for 10/0 (No. 32) and 11/0 (No. 31).  Thumb plane with wedge for 6/6 was another make, probably unmarked.


In July 2020, an example of a Buck/Norris No. 12 thumb plane came to market on Ebay U.K.  Here are some photos of that plane (please excuse photo quality).  In the 1908 Norris catalogue, the no. 12 was included, but by the time of the 1914 Norris catalogue, the no. 12 was replaced by the nos. 31 and 32.  These pictures reveal, however faintly, the dovetailed construction of the Norris (Buck) no. 12 thumb plane.  The front infill differs from the later no. 32 Norris thumb planes, and the toe is shortened, not unlike some of the Mathieson thumb planes.


Before the 1914 catalogue, Norris started making their thumb planes with cast “Patent Metal,” or “Unbreakable.”  Photo from Ebay, 2016.

“Unbreakable?”  Do not believe everything that you read.

Two Norris thumb planes, with thick 1 1/4″ parallel irons, bright ground and marked “Buck Tot. Ct. Rd.” Both planes marked and sold by Buck. In the foreground is no. 32, and in the background is no. 31.  The two examples were made in the early 20th century, and depicted in the Norris 1914 catalogue.

“The Metal Thumb Plane, English type …is 5 in. long, and …1 1/4 in. wide [cutter]; it has a long cutter, which answers for a handle, and is secured with a gun-metal screw lever.  It is, I believe, a specialty of Mr. George Buck, whose address will be found in the advertisement pages of this book.”From “Modern Practical Joinery,” by George Ellis, 1908.

This plane iron with the mark “Buck Tottm. Ct. Rd.”  has been found on a Kerr thumb plane as well as a Holland thumb plane.  The iron on the left appears to be a parallel iron, while the iron pictured with the Holland thumb plane is tapered.  Other Buck stamps on Buck thumb plane irons are smaller and more subtle.

Two  Norris No. 31 planes are shown below, in gunmetal, but without the front bun, which may have been the way the No. 31 was available when the gunmetal casting was first introduced–and then the rosewood infill at the toe was added some months later.  A clue in ascertaining this chronology is the use of an earlier Norris knurling pattern on the lever cap screws; this is the same pattern, set at 90 degrees, as what was used on the No. 31 models with a malleable iron casting.  Not to be ruled out entirely though, the gunmetal No. 31 without the front infill could have been a custom order.  Norris continued to offer custom made planes as late as the Rebate Mitre plane in 1941.

Norris No. 31 Thumb plane. circa 1930s.





Norris 31, in steel soled gunmetal and front infill. By Norris’ 1928 catalogue, this was how No. 31 was offered, rather than in “patent metal,” cusped lever cap screw, and open toe.

“…Certainly some of these planes, most notably Norris thumb planes, were marketed towards pianoforte case makers and the like.”  –C.R. Miller,


The Norris No. 31 gunmetal thumb plane shown above is a very late model.  Following details of this No. 31 thumb plane substantiate the assertion:

  1. Lever cap shortened in front of the fulcrum (more of the iron exposed immediately behind the bevel).
  2. Lever cap screw knurled in a general diamond pattern rather than the traditional Norris pattern in rows.
  3. Stamp on lever cap: lettering without serifs.
  4. Stamp on iron: lettering without serifs, (generally but not absolutely) indicating late 1930s production.  Postwar Norris irons also had a stamp with lettering without serifs, but Norris Thumb planes were not made post WWII.
  5. Sweated-on steel sole in 1 piece–rather than 2 used earlier, with the rear steel sole piece pinned to the gunmetal casting.  Pinning was done to prevent separation.  Utilizing the 1 piece applied steel sole on the late Norris thumb plane was a shortcut.

Here is another example of this late version of the Norris No. 31 thumb plane:

Norris No. 31 line-up: c. 1909-1918; c. <1924-1935; c. 1936-1942.

Line-up of Norris No. 31 Thumb planes l. to r.: iron casting, nib, and finial on lever cap screw; gunmetal casting, later diagonal knurling in rows, and two piece sole (small mouth); gunmetal casting, smaller lever cap, generic knurling, and 1 piece sole.










Norris No. 31 Thumb plane, circa 1936-1942, with “31” stamped on bed.

When this late Norris No. 31 Thumb plane was made, it was stamped “31” in the bed, and was probably the only 31 in the batch of planes being made at that time in the Norris New Malden workshop.  Therefore, only the model number “31” was needed to identify this solid mahogany part.  At this late date, care was still taken to make the bed fit to the inner casting.

Norris’ No A31 replaced the standard No. 31 in the c. 1930 catalogue, but in practice, the 1930s details of the actual planes point to both models having been produced during the same time period.


Norris No. 32 Thumb planes were offered in steel-faced gunmetal in their 1928 catalogue, for 26 shillings, the same price as Norris’ No. 31 Thumb planes with lever cap.  By 1930, the A31 Adjustable Thumb plane was offered for just a little more, at 28 shillings.  In the 1914 Norris catalogue, No. 32 was 10/6, and No. 31 was 11.  Around the late 1920s, early 1930s, Norris’ No. 32 thumb plane was no longer a less expensive option.  And by this time, a new plane coming to market utilizing a wedge and bridge was becoming increasingly anachronistic.  Customer demand was reduced.  Because of this, very few gunmetal Norris No. 32 Thumb planes were made, and examples are exceedingly rare.

That’s $5,278.50 before commission and tax.  After tax and commission, the price would have approximated $6,440.00.

A gunmetal Norris No. 32 appeared on the catalogue cover of a David Stanley International Auction in 1993.  Apparently, it was in mint condition, and also included was the original Norris box from the 1930s.

The late No. 32 had a bridge with convex sides, instead of the concave sides in the earlier version.  This convex bridge was similar, but not identical, to the bridges on the A31 Thumb planes and the Gunmetal  No. 28 Chariot planes.

This early dovetailed thumb plane has a separate heel plate, and the Norris No. 31 is cast gunmetal.  The Spiers No. 9 Thumb planes typically have a U-shaped bend at the back, and no separate heel.



Norris A31 Thumb plane, with full length iron.


The Norris A31 was not just a No. 31 with the infill bed mortised and an adjuster dropped in.  The gunmetal casting is 3/32″ wider than the no. 31 shown above, and 1/16 wider than my no. 32 thumb planes.  Standard alterations include an open heel, with protruding boat stern shape; adjustment thumbscrew with #11526 patent inscribed; “Norris London” marked bridge with convex edges; the bridge thumbscrew is indented, for finger placement, not unlike a Stanley 102 block plane.  The mouth on the A31s were generally tighter than the late 31s.

Some Norris A31 Thumb planes had mahogany infills rather than rosewood, which altered the overall appearance of the tool.  The front bun looks as if it may have been stained at one time (photo on the left).  Both images below have the “A31” mark missing from the wedge.

Here you can see Norris’ second patent No. 11526 dated 22 June, 1923, for the adjustable iron feature which enables fore and aft adjustments as well as lateral motions with one knob.  The Spiers thumb plane has a full Ward iron with a nib or sneck.




Related: Norris Chariot planes

Between 1914 and 1936, Thomas Norris continued producing specialist planes, while other known makers, such as Spiers, discontinued them (except Coopers’ Plucker).  Only Norris kept alive the traditional chariot, mitre, and thumb planes during this period.

Norris no. 28 chariot plane, sold and marked by Mitchell, a British dealer. "Patent Metal" stamped on bridge.

Norris no. 28 chariot plane, sold and marked by Mitchell.

Norris A28. From Norris’ 1930 catalogue.


John William Mitchell was a British dealer at 94 Newington Causeway, London between 1865 and 1910. Norris’ “Patent Metal” was stamped on bridge.  Most chariot planes were the bullnose type, like this one, with the mouth at the toe of the sole.  Also, chariots were shorter ~3 1/2″ and blockier than thumb planes.









Thomas Norris Jr.’s decision to continue making violin, chariot, thumb, and mitre planes after the Great War was conceivably informed by his grandfather Thomas Norris (1804-1886), who was a music engraver.  Music engraving was a prime example of the craft side of music.  And so was instrument making.   Violin, chariot, thumb, and mitre forms of planes were inextricably linked with the luthier’s tradecraft and piano manufacturing.


Buck/Holland Thumb Plane

Holland made planes at 68 Oakley St, Lambeth (1861-1870), then 93 York Rd. (1870-1890).  Holland took over the business of metal planemaker Charles Badger (at 93 York Rd. in 1869-70) in 1870. Thomas Norris worked down the street, at 57 York St., Lambeth London.

Holland/Buck gunmetal thumb plane with flange at heel, strike button, and tapered 1 1/4″ “BUCK TOTT’M CT. RD. “ iron.







Note the similarity with the wedge in the Holland thumb plane.  I am not aware of any Badger made thumb planes.



This view of the heel shows a distinct arris, which emulated the convex rear plate found on the earlier Kerr type of dovetailed thumb planes.  In this example, the body was cast in gunmetal and not made of joined body components.

Reasons why I think Holland made this thumb plane: 1. Side profile similar to other Holland thumb planes. 2. Influence of Badger in the wedge.  3. Early use of gunmetal in a thumb plane. 4. Buck iron points to a working relationship, which Holland had with Buck.


George Kerr Thumb Planes

Early thumb plane, with some chariot plane features, made by George Kerr, 36 Store St., Bedford Square, London (address c. 1864 in Williams London Trade Directory).  Earlier in his working life, George Kerr had been a piano action rail fabricator.  This thumb plane was included in David Russell’s, Antique Woodworking Tools, no. 1093.  Originally, it had a tapered 1 1/4″ Buck iron, but that got switched with 1092’s Ward iron, another Kerr thumb plane.  Kerr may have had a trading relationship with George  Buck, or he could have just walked around the corner to buy the iron while work was in progress on this thumb plane.  No. 1092 had an open toe, and that made it appear much more like a classic thumb plane.

Kerr thumb plane (attr.)

19th century English thumb plane, dovetailed and unmarked, although it may have had a visible stamp originally.  An early user tapped on the thick gunmetal bridge habitually.  Professionally-made dovetails on this plane are virtually invisible, with the exception of the ones for the rear plate.  The strike button at the rear (a cheesehead screw–now replaced with same) had been mightily pulverized, and probably slightly straightened the convex heel causing the dovetails to become visible there.  Fortunately, the hammering did not extend into the heel itself.  The Kerr thumb planes shown above, also had a separate heel plate, dovetailed to the sides.  On this example, the sides were cut for trailing dovetails into the sole which was part of the reason that the rear flange was made longer than most other English thumb planes.  Behind the bridge, the top edges of the sidewalls have a slight lip on the inner sides.  It’s an indication that those surfaces were burnished smooth rather than filed or sanded–an old method.  The infill bed, which was pinned to the sides, was also drilled out for lead weights, of the same type that would be installed in a quality piano keyboard in the factory.  This was a piano plane for sure, and it most likely came out of a piano factory.

Lead weighting adds mass, and the resulting inertia makes it easier to cut cleanly through difficult grain with a small plane.  This is the largest of all my English thumb planes at 5 7/8″.  It is also slightly deeper than the others, as the pictures show.



Unmarked Thumb Planes

This thumb plane may be cast iron or dovetailed.  It has an extra large lever cap, and a thumbscrew that looks a bit like early Spiers, or possibly Holland.  A mystery that may never be solved.

This gunmetal thumb plane has a flat heel like a chariot plane, but in all other respects, it has a thumb plane design.  It is simple yet elegant.

Heavy English Thumb plane in bronze.


With the bronze heel of this English Thumb plane 5/8 inch thick at the center, this is a heavy plane for its size.  The use of lugs instead of a bridge as well as the use of gunmetal suggest a maker such as Badger or Holland.  Since there are no other clues that are apparent to me at this time, I would conclude just as easily that it was craftsman made.

H. stands for heavy!

Not to be outdone, the maker of this Thumb/Chariot plane intercross shown below on the right, filled the bed with molten lead, and then filed it flush.  Hopefully using precautions.
