Abstract
An improved hand knife 20 of the type used for trimming meat with a rotary gear-driven ring-like blade 34 guided by a ring-like housing 30. The blade is retained by a partial peripheral flange 90 of the housing and a pivoted retaining shoe 36 secured to the knife hand piece 22. A securing screw 40 and an adjustable abutment 80 retain and position the shoe against the blade. The arrangement allows convenient blade changing. A handpiece 22 has asymmetrically flared recesses 56, 130, 132 adjacent the blade for promoting discharge of product particles that tend to accumulate. The shoe and housing substantially cover gear teeth 42 of the blade.
