The present disclosure relates to safety blades for use in utility knives, related assemblies and methods of manufacturing. More specifically, the present disclosure relates to safety blades for use in utility knives, related assemblies and methods of manufacture which limit user exposure to associated cutting edges.

The use of etchings into one or more places of a knife in such a way to maximize leverage allows for more precision and safety to be obtained by the holder, when the holder attempts to complete finer tasks with the knife. A knife can be comprised of three portions to the blade: one portion for chopping, one portion for fine tasks, and one portion for chiseling purposes.

A method for forming a cutting tool includes masking a metal base with one or more masks, the one or more masks including at least one variable permeability mask, and chemically etching the masked metal base to form a blade of the cutting tool.

A knife is provided that includes a replaceable blade element. The knife employs a blade carrier that is fixedly interconnected to or foldable with respect to a handle. The blade carrier selectively receives the replaceable blade element that is locked into the blade carrier by way of a hook and movable pin combination. The replaceable blade element is designed to be inserted within the blade carrier quickly, easily, and safely.

A utility blade is provided that includes a blade body having a convex quadrilateral shape. The blade body defines a top edge, a linear cutting edge on an opposite side of the blade body from the top edge, and a pair of side edges located on opposite sides of the blade body, extending between the top edge and the linear cutting edge. The blade body also defines a pair of openings located proximate the pair of side edges, between the top edge and the linear cutting edge; and the pair of openings are spatially separated from the top edge and the linear cutting edge. A top portion of the utility blade is contoured to fit within a holder that includes a pair of detents, and the pair of openings contoured to fit the pair of detents to position and hold the utility blade within the holder.

Provided is a cutting implement which is easily ground or which needs no grinding and is safe. The cutting implement is a cutting implement including an acting portion 3 that cuts an object to be cut, the cutting implement configured such that the acting portion 3 includes a main body portion 4 and a small thickness portion 5 whose thickness is smaller than the thickness of the main body portion 4 and the small thickness portion 5 has a width of 2.5 to 20 mm and a thickness of 0.1 to 0.5 mm.
