A standard flat-bladed utility scraper uses a standard (read: dangerously oversharpened) steel utility blade, or even a razor blade. But like standard steel cutting tools, the metal blade wears down quickly. Users are often left with a blade that’s too sharp or too dull, both dangerous in their own way.Advanced ceramics last much longer than steel, but other ceramic scraper manufacturers still use an unnecessarily sharp blade. So while their blades may not dull quickly, they still start out dangerously sharp.Slice blades have a unique finger-friendly edge that’s sharp enough to be effective, but still safe to the touch. This allows companies who use Slice to reduce injuries and lower costs.
