Presto fishtail jigged bone switchblade

Presto fishtail switchblade made by the Geo Schrade Knife Co of Bridgeport, CT sometime between 1929 and 1956. This knife was designated the model #6000S and was very popular with customers. It measures 4 inches closed and 7.25 inches open with steel liners. The blade is marked PRESTO MADE IN USA on the front and G SCHRADE in an arch over B'PORT, CT on the rear tang which means it was an earlier knife, likely made before 1940. The blade is full with some light scratches and light pits, very nice overall. The jigged bone scales (handles) are in good condition with a couple of hairline cracks through the front scale, but seems stable. The knife works well with the blade tip seating deep, good snap and good lockup open. Safety works. 100% money back guarantee including return shipping if not happy with this knife.
