This was given to me today and I am not quite sure what it is or was used for.
It measures 9 1/2" long, 3 1/2" wide and 1 3/4" high. The blade measures 7 1/4" long and the wooden wedge measures 6 1/4" long
The only mark on one end is a number 8 and on the other end it says W. Davidson then something else that I can't make out - looks like 3 characters and then in very small print the word Willinglaw.
I am not even sure what way the wedge is supposed to sit but if it is turned flush against the blade, it allows the blade to move in and out. If it is placed with the curved end facing the blade, it kind of locks it in.
As always, any information about use, age, etc. is always appreciated.
