I've never seen a precision cutter like in the OP. Interesting. I'm always scared of the tip of the exacto knife breaking and going into my eye. The precision cutter seems like it might be safer?
Just in case it's helpful to anyone, I recently got these, and they are WONDERFUL. They are the most teeny tiny scissors I've ever seen. I've been cutting very small detailed things, and these things come in so handy. I researched a bit and couldn't find anything comparable to these at this price, either.
