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.
