Instructions for Use
Our Ring Knives are meant to be worn on your finger, just like a ring. Any finger will work, but we suggest that you wear it where it is most comfortable. Generally speaking, the ring is worn with the blade on top of the hand, all the way back against your knuckle and facing the tip of your fingers.
There isn’t really a wrong way to use your ring knife, and after some trial time you may find that it works best on a different finger, or even your other hand.
Sizing Information
We understand that you don’t want to order the wrong size; if you know your ring size and where you expect to wear the Ring Knife, then you are all set. If not, here is some information to consider that may help.
Our metal band Ring Knives come in standard ring sizes 6 through 18, and our vinyl wrapped bands are available in standard ring sizes 4 through 16. These sizes are what you would find in a jewelry store. Our most popular sizes for ladies are 8 through 11 and for men, 13 through 16.
If you still aren’t quite sure, we suggest you order your knives a little larger than you think you might need. If you order Ring Knives that are too small, there isn’t much you can do to make them larger. If they are too loose however, the knife can be made to fit better by wearing it over a glove, or by wrapping string or tape around the band to create a custom fit. Keep in mind, too, that a person’s hand may naturally swell a bit as the workday progresses.
