"Perfect Cut" cutters

[mobarbq]

I hardly ever use it (the perfect cutter). My credit card-size stainless steel cutter from Cusano is one I use most often. Like other guys I like gadgets and have a variety, including a Shuriken and a Colibri grip. I guess if someone had a disability which caused them to have trouble making just a thin slice off the end, a "perfect cutter" might be helpful? I'd be curious to know if anyone does prefer them over more conventional cutters.
