Schrade Cut Co large bone double tip bolsters

Schrade Cut Co large double with jigged bone scales and nickel silver tip bolsters. This knife was made in Walden, NY sometime between 1916 and 1946 and is the largest of the three sizes of two bladed switchblades made by Schrade Cut Co. It's a model #7503 3/4T with clip/pen blade combination. The knife measures 3 3/4" closed and 8 inches with both blades open and it has brass liners and nickel silver tip bolsters. The small blade has three patent dates 09, 10 & 16 and is nearly full and mostly shiny with some pitting. The large blade has some loss from sharpening and is a tad short, but good overall with swedge grind, some patina and some scratches. The knife works well with both blades seating well closed, and open fully with average lockup. Both safeties work. Good working example of a vintage American large double bone handled switchblade.
