DC CAFCFirst Claim
1. A rotary knife comprising:
- a handle assembly including a handle supporting frame member and a head member extending from the handle supporting frame member;
a split blade housing for rotatably supporting an annular blade, the blade housing including first and second ends adjacent a split in the housing, a first bearing surface facing toward the blade and a second bearing surface facing away from the blade; and
a clamping assembly for releasably securing the blade housing to the handle assembly head member, the clamping assembly including a clamp body that engages the first bearing surface when the blade housing is secured to the head member;
wherein the clamp body includes a bearing surface that engages the first bearing surface of the blade housing and the head member includes a bearing surface that engages the second bearing surface of the blade housing, and further wherein at least one of the clamp body bearing surface, the first and second bearing surfaces of the blade housing and the bearing surface of the head member includes an area of scoring to inhibit movement of the first end of the blade housing relative to the second end when the clamping assembly secures the blade housing to the head member.

Abstract
A rotary knife having an annular blade, a split blade housing for supporting the blade for rotation, a handle assembly including a head member for supporting the split blade housing, and a clamping assembly including a clamp body for clamping the split blade housing to the head member. A portion of the split blade housing is provided with an area of scoring along a bearing surface that bears against the clamp body. Similarly, the clamp body is provided with an area of scoring along a bearing surface that bears against the blade housing bearing surface. The areas of scoring coact to inhibit movement of one end of the split blade housing with respect to a second end of the split blade housing when the split blade housing is clamped to the head member.
