This sheath is designed for the Shun Ken Onion and Kaji Fusion knives, but it may fit others as well. Be sure to take note of the pin placement near the snap, because with the flap snapped shut there is not much room for the handle to protrude above it. This is a small Shun blade guard for 3-6" long blade (depending on model), made specifically for the Shun Ken Onion and Kaji Fusion line small paring/utility knives such as the DM0516 (but does not work for the Edo line). Made in Poland, these are new old stock (these were bulk packed by Kershaw/Kai and transperant plastic cover may have scuffs/light scratches from production). Overall sheath size with lid closed: 3" wide x 6 1/2" tall. Possible blade size: 1 1/2" wide and up to 6" long (with snap closed, there is approximately 3/4" space above strap to the pin). Felt exterior with plastic lining.
