STAINLESS STEEL 18cm Japanese Picklock Stiletto Vintage 1960s automatic knife

STAINLESS STEEL 18cm Japanese Picklock Stiletto Vintage 1960s automatic knife with black & white scales. This knife measures 18cm (7 1/8 inches) open with brass D stamped liners, button & safety and nickel silver bolsters. The bayonet style blade is mostly full 98% or better with a little patina and lots of light scratches from sharpening/use and the ricasso is stamped STAINLESS STEEL. The scales look like horn, but pretty sure they are synthetic with a couple of tiny hairline cracks by the button and show signs of use/carry. The knife works well with the blade tip below the liners closed, opens well and good lockup with less than 1/16" movement each way at the tip. Brass button has heavy patina/age. Safety works, but is a little loose. VG+ condition.
