发明名称 Safety blade
摘要 A safety blade has a cutting edge 41 formed with a plurality of protrusions or projections 42 extending in front of the blade in a comb structure which extends from one end of the cutting edge to the other. The projections prevent the edge from contacting skin, but do not prevent the cutting edge from performing its function. Such a blade may be used in kitchen utensils and cutlery, such as steak or fruit knives, or craft tools or the like.
