I think I have one of those same cutters laying around. The one I am thinking of is a promo from Cusano, that calls the cutter "the perfect cutter". I was told at the B&M that it was designed to take just the right amount off, hence the "perfect cut". I does not work for torpedos as you noted.

Just a suggestion, but do yourself a favor and invest the 25-30 bucks in a good cutter. It really does make a big difference. I didnt think it would until I tried one. Just my .02.
