[Class 61 (i).] In forming a handle for cutlery, a foundation is cut from sheet metal and introduced, together with sheet vulcanized fibre or other plastic or semi-plastic material into a mould or die having a concavity 14 shaped to the form of the finished handle and the parts are pressed into the concavity by a projection on the male die to cause the plastic material permanently to conform to the shape of the foundation. A spring pressed side plate 23 co-operates with a fixed plate 22 to position the plastic sheet in the die and end plates 20, 21 of greater thickness than the side plates, locate the metal foundation which is introduced in a flat condition. Serrations along the edges and apertures in the foundation form keys to secure the plastic sheet thereto. Both sheets of material are cut to a width greater than the width of the cavity in the die and the foundation may be cut to a greater length, the ends being left free of coating material to form bolsters. For a pocket knife, the handle comprises two such parts clamped together, one on each side of the shank of a cutting blade, but for a hunting knife the foundation is arranged to be folded on itself to form two sides spaced apart to accommodate the shank of the cutting blade, the part of the foundation at the bend being free from coating material.
