I have carried these on my key ring for over twenty years.  Through the Boy Scouts, US Army, a Girl Scout troop, two children and countless adventures, these tweezers have pulled from myself and many others countless splinters, thorns, ticks and even stitches. They remain strong, sharp, precise, retain their shape and best of all, securely fastened on my key ring. They are easily cleaned and sterilized and still function as they do when new. I have given away dozens of these as gifts over the years. The best tweezers are the ones you have with you when you need them. Absolutely the best.
