The blade on this knife is nice quality bead blast 1045 (plain) steel. This spring assisted knife just needs a little push on the thumb stud and the spring pops the blade right out. This knife can also be activated by using the "flipper" on the spine of the knife. You just push the "flipper" and out pops the blade. Spring assisted knives are legal in most states. This steel knife has a beautiful rosewood insert on both sides. It also has a handy nylon sheath.
