The rotary cutter according to claim 1 including first a ridge on said handle and a tab formed in said actuating member, said tab including a second ridge positioned to engage said first ridge to hold the actuating member in the operative position.
Claim 4
Dependent Claim
31 words
The rotary cutter according to claim 2 wherein said handle includes a tab positioned to engage said tab on said actuating member to release said first ridge from said second ridge.
Claim 5
Dependent Claim
35 words
The rotary cutter according to claim 3 including a blade guard and means mounted on said actuating member for supporting said guard in a position to cover a portion of the edge of the blade.
Claim 6
Dependent Claim
24 words
The rotary cutter according to claim 1 including a blade guard mounted on said actuating member to cover a portion of the circular blade.
Claim 7
Dependent Claim
