Stanley in 1843, originally a bolt and door hardware manufacturing company located in New Britain, Connecticut.The Stanley Rule and Level Company was founded in 1857 by Henry Stanley in New Britain, Connecticut.Often, the steel casing just above the spur will be munged as a result of jamming a screwdriver, or similar tool, above the spur and twisting it.On this model, the steel casing has an extra screw on the spur side so that the casing won't distort around the spur.Earlier binders either purchased leather of the required thickness, sent it back to a leatherseller to thin it for them, or in the second half of the 19th C. Although today we tend to think of a French knife as having a gently curved cutting edge somewhat perpendicular to the length of the blade, and Salamon notes “This has a broad blade c. wide, bevel sharpened across the end like a chisel, either straight or at an angle.” (Salamon 1986, 57) Dudin illustrates a similar knife shown below.(Dudin 1997, 115) These engravings are detailed and carefully observed- note the leather wrapped around the handle for comfort.It is invaluable for conservation, because one can selectively pare areas to the precise thickness desired.
The spur is dovetailed into the right side of the steel casing.
For those trained in an English tradition, it is a common, useful tool for gradual beveling of leather, especially around the turnins and caps.
While a Scharfix or Brockman type paring machine is useful, you would have to do a lot of sanding if you want a long, gradual bevel found on English fine bindings, and for reducing thickness in the spine area.
This section is roughly 1/4" long, which makes it suitable for bullnose work. The amount of original nickel plating that remains on these planes has a tremendous effect on their value, but has absolutely no effect on their use.
The sides are ground flat and, supposedly, square to the bottom.
