All blades encounter small obstacles along their cutting paths, from specs of dirt to staples embedded in boxes. For softer metal blades, these distort the edge and eventually wear down the blade. Many advanced ceramic blades are also prone to chipping or breaking simply because they’re very thin or use a weaker composite material. Slice blades occasionally experience micro-chips along the edge. But because our blades have a wider cutting angle and we use 100 percent zirconium oxide (an extremely hard material), these chips are often literally microscopic and do not affect cutting performance. For this reason, even workers with heavy-duty applications can use Slice’s robust industrial blades with confidence.
