Boy, I could have used those pliers a couple of years ago when I was attaching a new belt to my Pfaff treadle. Instead I used an ice pick ..... jabbed myself into the meaty part of my hand just under my thumb. Thankfully, I pulled back just in time so that although I had a small puncture wound, my tetanus shot was up to date and no infection. Whew! Won't be doing that dumb thing again.
