Hammer Brand Imperial JM99PB Toothpick Black Imitation jigged bone switchblade

Vintage Hammer Brand toothpick switchblade made by the Imperial Knife Co of Providence, RI in the 1950s and was designated them model # JM99PB. Most of these had black wrapped scales, but I believe a certain percentage were made like this without the wraps. These are commonly referred to as imitation bone and are pressed hollow steel. The knife measures 4.25 inches closed and 7 7/16 inches open with steel liners, button & safety. The clip blade is 96% full with patina, light scratches and some spotting and the tang is stamped Hammer Brand USA with a picture of an arm holding a hammer on the tang and P 2170537 2201782 on the rear. Scales are in very nice condition. Works well with blade tip seating below the liners, good snap and average lockup with about 3/16" up and down at the tip and does rattle if shaken with blade open, as most of these do with a lot of use. Safety works. VG condition.
