A: Dear Valued Home Depot Customer, We have reached out to the manufacturer and their reply is, The auto lock on this knife prevents the blade from coming out unless you apply pressure to the black slider. It also locks the blade in place after you have exposed it, so that it will not go back into the knife as you cut.
A: OLFA offers two replacement blade options sold in-store and online: OLFA model numbers: AB-10S #9281, and ABB-10B #9148. As of 2018, both are sold in-store near paint tools. Note, this knife is 100% stainless steel. The blade is too. While 9mm blades are interchangeable, the only stainless option is AB-10"S" noted above. The ABB blade is a special 25% sharper black blade, though it is regular steel, not stainless. Choose the right blade for your application.
