HTK Company: Handy Safety Knife

Offered as a safe and efficient alternative to conventional box cutters and utility knives, the Handy Safety Knife ring knife features a curved blade.

This construction makes it nearly impossible for the user to cut him or herself—or anyone else. Worn on the finger like a ring, the knife is outfitted with a professional-grade blade and comes in four styles.

It can also be customized with vinyl wrap and different color options.
