Step 1 - Material to be nibbled is placed in the gap between the punch and blade channel
Step 2 - By squeezing the handles together, the punch will move down into the channel, cutting out a slug of metal
Step 3 - A scribe line can be followed by looking down on work in this position. A slot is cut by making successive cuts
Step 4 - To make a sharp 90 degrees turn, pull the tool out of the slot, turn the work 90 degrees and inset the tool again
By turning the tool before each cut, a 5/16"(7.9mm) minimum radius can be cut
Almost any size or shape hole can be cut by starting with a 3/8"(.5mm) hole
