    Does the job that it is supposed to do; definitely cuts paper and tape with ease. The size is a bit small for my employees though, and for my company's purposes I would have preferred a slightly different placement of the blade.

What Is a Ring Knife?

A ring knife is any kind of knife you can wear as a ring. Some are designed as weapons and some as tools, but for the most part, they’re worn on the finger close to the knuckle, like a traditional ring. The Slice® Safety Cutter Ring is meant to give the user maximum dexterity, so it fits near the tip of the index finger, more like a thimble than a wedding ring. This design gives the user more control over cuts.


Some ring knives have exposed blades while others use a hook design to grab and cut string. In almost all cases, the blade is oriented so that it extends from the top, or outside, of the hand. Slice’s version places its micro-ceramic blade under the finger pad for comfort, safety, and control.


How Is the Slice Ring Knife Finger Friendly®?


The term “finger friendly” can be confusing with you’re talking about a tool you wear on your finger. When we say “finger friendly”, we’re talking specifically about the blade. The 10583’s micro-ceramic blade extends a mere millimeter (approximately) from the base, which means it’s very difficult to penetrate skin. In addition, the 100 percent zirconium oxide blade features our proprietary double-edged grind that is much safer to touch than traditional blades. The Safety Cutter Ring is safe enough to wear between cuts and is meant for continuous wear while performing repeated cuts.


What Can I Cut With the Safety Cutter Ring?


Despite its safer edge, this handy little ring knife can open a variety of packages, from paper and plastic bags to thin card stock, clamshell packaging, reinforced plastics, and plastic netting. It’s ideal for workers opening packaging or manufacturing materials over the course of a shift and is meant to be worn continuously for efficiency and comfort.


Will my Safety Cutter Ring Fit Me?


Our ring knife is designed to fit most adult hands. It includes an inner silicone adapter ring for smaller fingers, which can be removed for larger fingers.


Is This Tool Safe Around Children?


All Slice tools are much safer to touch than their traditional counterparts, whether metal or ceramic. That said, common-sense safety rules should always apply, including supervision for any child using a cutting tool. This ring is designed to fit snugly on adult fingers, so smaller fingers will not have the same level of control over the direction of the blade, and that should be taken into account.
