Adjustable handles for piano regulating tools became popular for the mobile piano technician relatively soon after their introduction around 1900. Since a good number of regulating tools were made to be compatible with it, including screwdriver blades with sizes up to 5/16″ for general driving, these handles were used constantly. In order to accommodate the different functions of all these tools, Frank Hale at Tuners Supply in Boston offered their combination handles in small, medium, and large sizes. As far as I know, there is no current supplier who offers three sizes, and Hale was not known for having a selection of tools as large as Hammacher Schlemmer or American Felt Co.
With using combination handles, piano tuner technicians were able to save space and lighten their load when carrying their toolkit from job to job. When field work was done in a large metropolitan area, and public transportation was used, every extra ounce of weight made a difference. I can attest to this personally, as I used to take the subway to various jobs during part of my years at at Steinway Hall in Manhattan.
By going to combination handles, instead of individual handles for each task, the piano technician gained something but lost something as well. Individual handles would be made specifically appropriate for a given task, but they would be bulky and unwieldy when carried in quantity. When Hale offered three sizes of adjustable handles, he was attempting to compensate for this loss of appropriate specificity. A good example of correctly-sized handles for the tool and the task can be found among selections of good vintage and antique chisels; many modern chisels though, no longer have appropriately sized handles. Because adjustable piano action handles were in use so frequently for a large range of tasks, it was important that the handle be appropriate not only for the hand of the user, but for the tool that was attached, and for the specific task engaged.
Examples of handle matching:
- Small drop screw regulator, which was also for adjusting the grand balancier and the grand jack. This is a delicate and fine tool; the metal shaft is thin and the socket is small in order to pass between grand shanks, regulating buttons, and the most narrowest of places, let-off dowels encountered on many grand actions. In order for the hand to be close to the work performed, the shaft was made short. The handle is commensurately small, with a faceted middle section for situations where a little more resistance was encountered—facets also prevented the tool from rolling off the workbench. A deerskin covering for the index finger, thumb, or palm–depending on the particular task at hand–was applied with bridle tacks to the back of the handle.
A huge octagonal handle was used on the key spacing tool. Many key spacing tools from 1880 to 1920 were large and robust like this one, unlike the smaller ones designed for use in the combination handle. These larger versions of key spacers were intended for pianomakers, and the initial spacing during the set up of a keyboard required a more exerted wholesale movement of keys, rather than the touch-up that is generally performed in the field later on.

It is also why, I believe, there are many early key spacers which are longer than 15 inches, not including the handle: it allowed the regulator to stand back and look at the entire keyboard at once, without having to stop working. Stock Nos. 3363 and 3364 were Tuck cocobolo handles, London pattern, to be individually fitted to each tool.

C.H. Lang’s Combination Handles

C.H. Lang, 1905: “All regulating tools to fit [handle] 20 cents extra, which is nothing compared to all the trouble with the wooden handles.” Lang also referred to the problem of splitting wooden handles, which happened often when the tang was inserted with too much force.

Shown below is an unmarked combination handle, with ebonite instead of hardwood, and metalwork that matches that of the Lang machine shop. This adjustable handle was designed to take the standard interchangeable regulating tools that we use today, but with a friction fit and clutch, rather than a collet. I believe that C.H. Lang offered this handle without including it in his 1905 catalogue; it was found in an old toolkit with other Lang piano tools. Further down this page, two more friction fit adjustable handles are shown, both with American Felt Co. details, but also not included in their catalogue.

Immediately after buying out Lang’s machine shop, Lyon & Healy continued making all of Lang’s piano tools, complete with the Lang proprietary stamp. After a year or two, this changed, and the Lang name was eliminated from catalogues, advertising, and the actual tools. Unlike most of the other ex-Lang tools, the Lyon & Healy Combination Handle (version 1 shown here) would go through two more iterations during the short tenure of L.& H., which ended in 1928.
Lang’s policy of exclusively selling piano tools was changed immediately. Lyon & Healy promptly added piano materials, hardware, and parts for their line of piano supply merchandise.



Only two years before Lyon & Healy exited the piano supply business, and sold out to Tonk Brothers, they saw that offering a combination handle which accepted the standard used by American Piano Supply (1914-1927, pre-Hammacher Schlemmer), and Hale would be the way forward. This particular handle (L.& H. Version 3) looks like it may have been a repurposed conversion from a more general purpose interchangeable handle, but version 3 has a ferrule similar to version 2, so it was probably made in house.
Hale’s Combination Handles

Hale combination handle 1938. Three sizes were offered, from the late 1920s, until c. 1942, which was a lot considering the rather spartan amount of tools offered in the Hale catalogs. Today, two sizes, at most, are available from any one supplier of combination regulating handles.












Early General Purpose Combination Tool With Hollow Handle for Storage
Here is an early example, by Millers Falls, patented Jan. 14th, 1868 (Amidon jaw chuck). This same chuck was also used on the Millers Falls #16 brace, which was intended for pianomakers. No. 16 had an unusually narrow 4-3/4″ sweep, consistent with the traditional pianomaker’s wooden braces, and was manufactured from 1884 to 1901.


During the Civil War, soldiers were required to perform multiple mechanical tasks, in order to maintain all the artillery, and other equipment on and off the battlefield. With other new technologies, such as the telegraph, the railroad, and anesthesia, came the need for technical support and and maintenance. Veterans of the Civil War were often “jacks of all trades;” back in the Reconstruction era, this did not have a negative connotation, it was an advantage. Wishing to utilize the new skills learned in service of their country, Civil War veterans wanted to use a large range of hand tools. Not everybody had the resources or the space, however, to buy a large amount of tools: this created the market for multi-tools, such as the Millers Falls Multi-Handle example patented in 1868, and also the Stanley Combination planes, such as the Nos. 45 and 55.



A difference between the Miller Falls type of tool handle and the patented handle shown below is that lateral and longitudinal movements of the tool are held in check by two separate functions in the tool, in a way not unlike the present piano regulating combination handle. This differs from the older tool handle above, in which both potential movements of the tool bit are controlled by one piece of hardware, the collet, or in this case, the chuck.

L.S. Davidson’s combination handle was the earliest US tool handle patent—with a reference to piano work—that I’ve found. Here is some of the text for the 1904 tool handle patent:

Pad Handles, Dating back to the 18th Century

Going back further in time for multi-tools, we have the Pad handle, which was included in the 1791 tool inventory of Christopher Gabriel. The chuck accepts a smaller version of bits made for the brace, with a nick cutout to engage the spring lock. This particular rosewood pad handle by Bagshaw & Field was a late example of the type, circa 1880.


The Pad Handle was developed in the late 1700s in order to cater to the desires of an emerging class of wealthy British individuals, who owned their home, and were desiring nice things, for maintenance tasks around the house, but also for hobbyists, who wanted to work on personal projects in their free time. Companies such as Holtzapffel and Moseley, in London, would market their attractive tools in upscale showroom settings in retail districts. In Birmingham, and the English Midlands generally, these small tools were called “toys,” during the 18th century, and possibly earlier. The term “toys” also applied to small practical objects, such as hooks, hinges, and buttons made of various materials. Not until the late 19th century, was the word toys associated with playthings for children in England.

More Early Piano Combination Handles

Between the turn of the twentieth century and 1910, all the major piano suppliers offered their own version of interchangeable combination handles for action regulating tools. The American Felt Co. drawing of their Adjustable Tool Handle was retained for the subsequent American Piano Supply (A.P.S.) Catalogue from the mid-1920s.







I’m not sure who sold these, perhaps American Felt Co. by process of elimination. H.S. offered combination handles that accommodated the traditional tang.

Combination Handles Made After 1975

John Ford made his combination handles from walnut wood. Ford’s early thumbscrews were brass-anodized steel in the 1970s, then solid brass in the 1980s. Ron Conors had one of these worn down to nothing. The APSCO handle was in rosewood, and purchased circa 1982; it may have been one of the last batches of product using Amazon rosewood. Notice the contrast of the wood as compared to the Yamaha regulating handle, which looks more like an Indian type of rosewood. The large Yamaha handle was purchased around 1998 and the small Yamaha handle, which I used a lot, was purchased in the 1980s, when these tools were first imported to the U.S. en-masse. There is a difference in fit and finish: the 1980s example is much more refined in both the machining as well as the plating. The Bolduc handle is made of a red mahogany, and has an asian-style floating collet. It is possible that the hardware was bought in, and the handle was turned in-house. The Chinese handle, in beechwood is huge, and would be suitable for using a screwdriver to open piano case screws, among other things. Quality on this large Chinese beech tool handle is good.
This Combination Piano Regulating Handle has hardware that is similar but not identical to the Yamaha Handle. Not sure where I got this handle, but it was sometime after 2008 or so. Also, the turning and facets on the handle are similar to the Yamaha type.
