Stanley No 18 Sliding Bevel Guide

This guide to the Stanley No 18 “Eureka” sliding bevel is not intended to be a fully researched type study at this time. Variations known to the author are presented here with basic date ranges and have been lettered to facilitate discussion and reference. Later variations with the 18TB or other number designations are not included at this time. This is still a work in progress and can change at any point. If you have a bevel that differs from any displayed here, please contact me. Thank you to Chris Widick for pushing me to do this guide and sharing his research.



A

1874~1895

Known as Sargent’s July 22, 1873 patent bevel, this was offered starting in the 1874 catalog. It was the first all metal handled bevel made by Stanley. It features stippled oval grips which have been japanned black. Both sides of the handle are identical in thickness and style, with no markings. The patent info can be found stamped parallel or perpendicular on the blade. Parallel marks may represent the earliest production. [Full Image]

B

~1895-1898

Same patent design as A, but with cosmetic differences. One side now sports “STANLEY” and the grip areas are nickel plated with the rest of the handle. The Patent info is now stamped perpendicular on the blade. Both sides of the handle remain the same thickness. Less common than A and probably represents the last few years of Sargent patent production. [Full Image]

C

1898-1908

A new mechanical design change from A/B, this style can be seen in the 1898-1907 catalogs. Does not appear to be a patented design. Easily spotted by the large slotted screw on the rod side. No change in the handles cosmetic design, however the non-rod side of the handle is now thinner. No longer any markings on the blade. [Full Image]



D

1908-1913

The mechanical design changes again from C, with a new patent by Christian Bodmer dated July 14, 1908. All further bevels utilize this patent. Handle design remains unchanged with the notable exception of the top, which now features small “steps” as the sides transition to the curved top. “PAT. 7-14-08” is stamped parallel on the blade.

E

1913-1920

The handle casting is changed and “STANLEY” is now cast in a notched rectangle. The opposite side reads “PAT’D 7-14-08” The thumbscrew is stamped “STANLEY NEW BRITAIN. CONN. U.S.A.” in two lines. Blades are no longer marked from here on. [Full Image]

F

1920-1925

Same as E, except now reads “U.S. PAT. 7-14-08” on the handle and “STANLEY MADE IN U.S.A.” in two lines on the thumbscrew. [Full Image]



G

1925-1926

The patent date is no longer present on the handle. It has been replaced by “No. 18 - 8 IN” (or 10 IN). The style of stippling has changed as well. Uncommon, and along with H, probably only offered far a very short time. The 12”, which was introduced with I, uses the same size handle as the 10”, and this may have been the reason for no longer casting the size into the handle. (Photo courtesy of Charles Bush).

H

1926-1927

No longer a stamp on the thumbscrew. The handle now reads “No. 18 STANLEY 8 IN” (or 10 IN) and “MADE IN U.S.A” on opposite sides of the handle, both in notched rectangles. Uncommon, and along with G, probably only offered far a very short time. The 12”, which was introduced with I, uses the same size handle as the 10”, and this may have been the reason for no longer casting the size into the handle. [Full Image]

I

1927-1945

Handle now just reads “No. 18 STANLEY” and “MADE IN U.S.A” on opposite sides of the handle, both in notched rectangles. No longer has the size cast into the handle. 12” size appears to have been introduced with this style. [Full Image]



J

1940-1945

Identical to I, but stippled grip is japanned black instead of nickel plated. Likely a wartime measure. [Full Image]

K

1945-1960

Stippled grips now take the form of a notched rectangle rather than having round ends. The one side now reads just “STANLEY” in the notched rectangle while “No. 18” has been moved to a separate small perpendicular box toward the bottom of the handle. [Full Image]
