My water's frozen over so to do a "test drive" will have to involve a drive to the pet aquarium.
I'm in one of those moods. I drove a sliver of wood under my thumbnail 3/4 of the way in. I had to have my Aunt yank it out while I bit down on a carrot. Hurt! Bleed! Disinfect- Hurt Some More! Now I'm a ball of adrenaline.
