Abstract: The present utility model discloses a utility knife with dual blades, comprising a housing having an opening at both ends, a blade carrier which is mounted and is movable within the housing, a movement assembly connected to the blade carrier for driving the blade carrier to respectively move in a direction towards both ends of the housing, wherein it further comprises a stop member. The blade carrier is provided with an abutment portion thereon, and the stop member has a stop portion being able to change its position with respect to the abutment portion, so that the blade carrier can move in a single direction so as to prevent the blade carrier from accidentally sliding and pushing the blade out to injure a user.

Abstract: The present invention discloses a cutting assembly. The cutting assembly includes a substrate, a cutting edge, and a welding portion. The substrate includes a first metal portion, and the first metal portion has a first side surface. The cutting edge is formed by overlapping a second metal portion with a third metal portion used for an edge, the second metal portion is of high-strength alloy steel and has a second side surface, and the third metal portion is of high-speed tool steel and has a third side surface. The welding portion connects the first metal portion and the second metal portion. The present invention further provides a method for manufacturing a cutting assembly, including: welding a composite steel strip to a substrate, to form a blank body of the cutting assembly; and then performing low-temperature tempering treatment on a welding portion.

Abstract: Disclosed are scissors, which comprise handles and scissors heads, the handles comprising a first handle and a second handle, the scissors heads comprising a first scissors head and a second scissors head, the first scissors head being provided with a first blade and extending from one end of the first handle, the second scissors head being provided with a second blade and extending from one end of the second handle, and the first scissors head being pivotally hinged to the second scissors head via a pivoting structure, wherein the first scissors head and the second scissors head have a small width to thickness ratio at the connection between the scissors heads and the pivoting structure. The scissors greatly increase the rigidity of the scissors head, enhance the shear-compression intensity of the scissors, facilitate the cutting of thick objects, and meet the requirements of various objects to be operated.
