Abstract

In parent patent, a method encloses the tang of a knife positioned in the recess of a mould by a synthetic material such as a polyamide by injection. In this addn., a mould as described in calims of the parent patent has on each upper and lower mould detail projecting into the cavity for the handle, at least one peg for centralising the tang of the knife blade. The peg of one mould half is opposite to the peg of the other; the distance apart of their end faces being equal to the thickness of the tang, so that when the mould is closed, the end of each peg is in contact with the tang. The pegs, of which there are three, have the form of a truncated cone with a flat end face parallel to the surface of th tang. If the thickness of th tang relatively to that of the knife handle enrobing it, is only slight, the knife handle may be warped. To overcome this, pegs are used to support the tang against the force of the extruded material, and this has not only proved satisfactory but also has a pleasing aesthetic effect resembling the rivets of wooden handles.
