US 4,575,938 A · Meat trimming knife

Abstract

An improved hand held meat trimming knife of the type which has a ring-like blade rotatably mounted on a blade holder for trimming meat from bones. The holder is mounted on a frame which is attached to a handle. The frame includes a pair of arcuate shaped arms on which the blade holder is secured by a pair of attachment bolts. One of the arms is formed integrally with the frame and the other is removably secured thereto by a locking collar slidably mounted on the handle. The blade holder has sufficient resiliency enabling it to remain attached to the removable arm and be expanded outwardly from the remaining portion of the frame upon disengagement of the arm from the frame enabling a blade to be easily installed on and removed from the expanded holder. The holder is formed with a blade supporting channel throughout a major portion of its circumference to trap and mount the blade thereon. An adjusting means is formed on the integrally attached arm for adjusting the inner diameter of the blade holder to compensate for wear of the blade and holder to prevent a smooth running engagement therebetween.
