Busy restaurants need to rely on sharp knives. One of the ways to make sure your knives stay sharp is to store them properly. Storing knives by mounting them on heavy-duty wall magnets by their blades is the most effective way to keep them sharp. Wooden knife blocks are also effective, but more so if you store the knives with blades up instead of facing down. When the knives are slid into the slots in the wooden block with blades up, the weight of the knife rests on the dull side of the blade, keeping the cutting side sharper longer.
