ABSTRACT:
Knives including a cutting blade and one or more wider non-cutting runners projecting slightly beyond the cutting edge of the blade and preferably at both ends of the knife blade. The runners prevent scratching of a substrate on which the material, normally a comestible, is being cut. On each runner there is provided on either side a beveled ramp inclined toward the adjacent cutting surface which acts very much as a plowshare to push up the material being cut against the cutting blade. This prevents a thin strip of material which would otherwise not reach the cutting blade and is particularly important with comestibles such as meat, which are sufficiently tough to permit forming such a thin strip. Where knives are manufactured, the ramps or plowshares can be incorporated in the knife blade when it is manufactured. However, there is included the provision of attachable runners for knives which have already been made. These runners, which are of the same shape, are provided with a groove in which the cutting blade extends and are attached to the blade firmly, preferably by a strong, waterproof adhesive, such as an epoxy cement. Blades may be inserted in a handle designed to receive them where a number of blades are desired without the cost of separate knives.
