Supercoup NR1 Nibbler Shears
Product Review (submitted on April 3, 2011):
Tried it out on some 20ga mild steel and it worked OK but it is a serious hand pincher. When it pops through and the handles close all the way Watch Out!. First time I tried them on 18ga mild the blade broke on the first cut. Not a good value for the money, good thing I got them on sale.
