Claims19
A trimming knife comprising:
- a blade having a straight leading edge, a straight trailing edge, a straight lower cutting edge, a squared leading corner between the straight leading edge and the straight lower cutting edge, and a squared trailing corner between the straight trailing edge and the straight lower cutting edge;
- and
- a handle comprising:
- a spine to receive the blade;
- a handle body including a gripping portion configured to receive a hand of a user;
- the spine distal of the gripping portion to receive the blade;
- a blade guard configured to protect the squared trailing corner of the blade with the blade received in the spine;
