Don't Be Silly, Use A Glove
Buy a cut glove. What is a cut glove you may ask. Have you ever grated your knuckles while grating cheese? or while using a mandolin to slice nice even thin pieces of cucumber or radish….sliced a nice even piece off your hand? Very sharp tools are very useful but need to be used with care and attention.
A cut glove can save a lot of bloodshed and bandaids. Designed for things like shucking oysters this simple glove can save your fingers. You can grate cheese or anything you use a grater for with abandon and not worry. For between $10 and $20 it is a very good investment.
