Opinel No 8 stainless steel blade. Blade length 8.5cm. This knife has a locking collar, that keeps the blade open or closed. The blade is made from Swedish Sandvik steel modified 12C27, which requires no special care. Of course all pocket knives should be kept dry and well maintained. The blade is stamped 'Opinel Inox' (stainless steel) to distinguish it from the carbon steel version. Made in France.
