Standard steel, so very sharp, self-sharpening but not rust-proof. The handle is made of pear wood. Handle length 11 cm, blade length 8.5 cm. Weight 45 g.
The French Opinel knives are famous, good but inexpensive. They have a very simple but reliable blocking system for the unfolded blade - a retaining ring at the end of the handle is turned as far as it will go and then locks the blade reliably in place.
