Is It Sharp Enough

Is it sharp enough? I ask testing the edge with my thumb is it the right knife? I wonder looking for the right one does it slide across my skin fast enough to shave the hairs from my arm? not sharp enough if not I won't use it I could sharpen it I could sharpen any of them sharp enough to slice in such a way that makes my skin crawl away from itself, apart my nerves cry so softly it's just a gentle whine very little blood and no more pain tonight
