This is a slicer for cutting food. It has a spring-loaded handle, so you just push it down to cut the food. It is safer than a knife because it has a guard that keeps your fingers away from the blades. You can use it to slice bread, cheese, fruit and vegetables. This slicer is especially good for cutting tomatoes because it doesn’t squish them like a knife does. You can pull it out of a drawer, and expand it in a matter of seconds..
