KA-BAR Lever Stag transitional switchblade

Nice old Ka-bar lever knife with stag handles. This knife was made by the Union Cutlery Co of Olean, NY most likely between 1930s and early 50s. It was designated the model 21105 and it measures 4.5 inches closed and 8 inches open and has thick brass liners. The bolsters and lever are made of nickel silver. The blade is 99% with nice even patina. Can see some of the original finish hiding underneath and it's marked KA-BAR on the front and UNION CUT CO OLEAN NY USA on the rear. The stag scales are in nice condition with no cracks or chips. The knife works great with the blade tip seating deep, strong snap and super Tight lockup open! This is a transitional knife made between the older Teardrop lever knives and the newer rectangular lever with lines (grooves) to give better control when opening the knife. The older teardrop levers were wider and accommodated the thumb when opening, but when they changed to a smaller rectangular smooth lever customers had some trouble with thumbs slipping a bit when opening so they added the grooves later for better control. It works fine, but I can see how the grooved levers give better control. Interesting and very nice old Kabar switchblade. 100% money back guarantee including return shipping if not completely satisfied with this knife.
