This is a rare knife made in Japan, not the Taiwan made existing one which is called Safe Keeper III. It comes with the original tooled leather sheath with clip for belt or boot. Blade length 2.75 inches and overall length is 4.75. This is the hardest blade that I ever owned, I penetrated an oil drum with it because they said it was capable of doing it and it did for sure. AUS 8 steel with Rockwell hardness rating at 58-59. The shealth requires retouching and the knife needs a deep cleaning and sharpening but I am taking those factors into consideration in the price.
 
You can not sharpen this knife normally, requires special equipment that knives collectors may have but I do not. However Cold Steel offers free sharpening on all Cold Steel brand knives! (Just found out)
