Giant 25cm Japanese Vintage Lever Brass & Chekered bone automatic knife

Vintage Giant Unmarked (sterile) 25cm Japanese Lever Brass & Jigged bone automatic knife made in Japan in the 1970s most likely. This is the largest Japanese lever release knife that we've ever come across. Most of these knives measure 19cm, or less and were made in four more common sizes between 14 and 20cm. This knife measures 24.7cm (9.75 inches) open and 5 3/8 inches closed with brass liners, lever, lanyard ring & pins. The long clip blade is 100% full with original finish and no maker's mark. The checkered bone (crosshatch) is in excellent condition and measures over an inch across. The knife works great with blade tip below liners closed, good snap and locks open like new with a hint of down at the tip. No rattle if shaken with blade open except the lever. Nearly new condition. This is a MUST HAVE for any collector trying to collect all sizes of Japanese lever knives.
