Flylock Hunter #11000 Large Single Black Wormgroove switchblade knife

Antique Flylock Hunter Large Single Black Wormgroove switchblade knife made by the Flylock Knife Co, a division of Challenge Cut Co of Bridgeport, CT in the 1920s. This is the largest switchblade made by the company and it was designated the model #11000. It measures 5 inches closed and 8 1/2 inches open with steel liners and bolsters with nickel silver button. The blade is about 1/4 inch short with a little loss from sharpening, but overall a nice blade at about 90% and shiny with some light scratches and some scattered light pit spots. The tang is stamped Flylock REG US PAT OFF over US PAT 3-5-18 and backside is marked THE FLYLOCK KNIFE CO B'PORT CONN. The black bakelite worm groove scales (handles) are in great condition with no cracks. The knife works well with the blade tip deep and centered in the channel, good snap and below average lockup with about 1/8" movement both ways at the tip. Rattles if shaken with blade open as most of these do that have seen use over the past 100 years or so. Nice working example of a nearly 100 year old American made switchblade knife. VG condition.
