Edgemaster Cigar Jack 1950s Vintage Blue swirl switchblade knife

This is an Edgemaster model 108 cigar switchblade made by the Federal Knife Co of Providence, RI between 1947 and 1954. It measures 3 3/8 inches closed and 5 13/16 inches open with brass liners, steel button & nickel silver safety. Blade is 95% full and shiny with some light scratches some pitting and a small nick in the cutting edge and is stamped Edgemaster USA on the tang. The blue swirl synthetic scales are in good condition with just a little shrinkage and no cracks. The knife works well with the blade tip seating deep when closed, opens fully with a slight delay and very good lockup when open with just a tiny bit of movement at the tip.  Safety works. VG- condition.
