Abstract: A scraper includes two shells juxtaposed and soldered together, a blade combined with the two shells, and a connecting member combined with the two shells. Each of the two shells has a receiving space, a plurality of first soldering portions, a first opening, a first slot, a second soldering portion, and a third soldering portion. The blade has an operation portion and a first mounting portion. The first mounting portion extends through the first opening into the receiving space and has a fourth soldering portion combined with the second soldering portions of the two shells by soldering. The connecting member is located in the receiving space and has a second slot aligning with the first slot. The connecting member has two ends each provided with a fifth soldering portion combined with the third soldering portion by soldering.

Abstract: An interlocking double throwing knife comprises: a first opposable throwing knife having a first blade and a first handle attached to the first blade, where the first handle has a first receptacle for housing another blade; and a second opposable throwing knife having a second blade and a second handle attached to the second blade, where the second handle has a second receptacle for housing another blade. The first opposable throwing knife and the second opposable throwing knife interlock by simultaneously inserting the first blade into the second receptacle and the second blade into the first receptacle such that the first blade and the second blade are sheathed within opposing knife handles.

Abstract: A hollow handle flatware includes a main body extending between a service end and a handle end. The main body includes a service portion at the service end and a handle portion at the handle end. The hollow handle flatware also includes a handle part, which is formed separately from the main body and permanently fixed to the handle portion of the main body to form a hollow handle. The handle part and the handle portion of the main body enclose a hollow chamber. Also disclosed is a method of making a hollow handle flatware by separately forming a main body and a handle part and joining the main body and the handle part as a unitary hollow handle flatware.

Abstract: A method for making magnetic handles includes step 1 of mixing magnetic powders into plastic material; step 2 of plastic injecting the mixture of the magnetic powders and the plastic material into a handle; step 3 of magnetizing the handle by being connected with electric poles, and step 4 of final fishing the handle.

Abstract: A shaving system includes a replaceable shaving cartridge and a shaving razor handle. The replaceable shaving cartridge has a housing carrying blades, a guard, a cap, and a camming surface. The cartridge includes an interconnect member having a pivotal support structure that pivotally supports the housing and a base structure adapted to be removably and fixedly attached to the handle. A shaving razor handle has an elongated hand gripping structure and a cartridge support structure extending from an end of the hand gripping structure. The cartridge support structure has an extension with outer side surfaces that mate with inwardly directed surfaces of a recess on the cartridge and an end surface with an opening. The extension has an asymmetrical shape to ensure proper orientation. A spring-biased plunger is retained in the cartridge support structure and extends through the opening of the cartridge support structure.
