Cut-Protection Rulers
A safety guard or finger groove prevents your fingers from getting in the way as you cut with these rulers. A rubber backing holds them in place while you’re cutting. These rulers are aluminum, so they’re lightweight and resist corrosion.
Rulers with a safety guard have a barrier that blocks your fingers from your knife while cutting.
Rulers with a finger groove create traction to prevent your fingers from slipping over the edge while cutting.
