Knifes: they will cut you. Not out of hostility or resentment, but because they're knives, dummy. Magmate's Magnetic Blade Guards will protect your precious fingers and keep your knives sharp at the same time.

The PVC sheaths won't save you from cuts you might sustain during some clumsy chopping, but you sure won't reach into the drawer and get a hand full of blade. The guards come in two sizes, a smaller one for $20 and a larger for $25. They're brightly colored and happy, and when you're done with your mincing, you snap them securely over your knives.
