Finger Knives Ring Utility Knife to Cut String 12 pcs (Random Color)

I use these in the kitchen to tie and wrap meat after curing and before hanging. That means your hands are contaminated, and scissors are a pain to use. i keep one of these on a pinky, and it works great!I hand wash and dry when I wash my hands. I have several of the aluminum version, this is just as good, and are cheap enough to throw away when dull.I am happy.

Works well but really tight fit for finger, couldn’t stand to wear for too long

These actually work nicely at cutting threads. I wear the ring on my right hand ring finger. It doesn’t give a clean cut of thread, it frays the edge of the thread. I find it comes in handy & is comfortable to wear. I wasn’t able to adjust the plastic circumference as the plastic is very stiff.

Doesn't cut very well, and would pretty much fly off your finger

Doesn’t cut well. Flys off when trying to use.
