be it a switch blade (opens from teh side) or a stilleto ( opens from teh front) it wouldnt do much upon opening. Stelletos are weak, shitty springs that need some help opening all teh way and locking, a switch needs a bit of a side flick to open it as well, either would open all the way and the switch wouldbe a bigger problem. it would be able to gather and cut inside tissues.
I doubt it would do much though since its impossible to ever fully open in a confined space with no assistance
Let's agree to respect each others views, no matter how wrong yours may be.
