Abstract
1439515 Hard knives TOMORROW ENTERPRISES Inc 10 July 1973 [24 July 1972] 32941/73 Heading B4B A cutting tool, e.g. a table knife 10 is provided with a cutting edge 18 terminating in a damagepreventing top 16 having a smooth surfaced contact portion 25a such that, during use, the downward forces are transmitted from the tool to a work-support surface 19 over an area rather than concentrated at a point thereby substantially preventing scratching or cutting of the support surface. As shown in Fig. 1 a table knife having a serrated cutting edge 18 is provided with a rounded tip 16, portion 25a, Fig. 4, thereof being rounded as shown in Fig. 8 in order to prevent damage to a work surface. When the knife is used at various angles; the cutting edge may be non-serrated. As shown in Fig. 4, the rounded portion is honed from a junction point 22a with the knife edge 18 such that it widens out until it blends into the thickness of the blunt edge 28a. This tapering effect causes less drag as the knife blade moves through the object being cut. The knife may also be formed with damage-preventing tip 30, Fig. 1 having a planar surface and that in combination with the tip 16, the knife edge may be moved parallel with the work surface 19 without cutting into the latter.
