If you or your staff works in food preparation, your knife is an invaluable tool. However, knives can be dangerous, and the most dangerous kind of knife is a dull one. There are several reasons that this is true. The edge of a dull knife does not slice cleanly, making it much harder to control, and more likely to slip. You also need to use more force to cut with a dull knife, so even though a sharp knife has the potential to inflict a deep cut, the extra force needed to cut with a dull knife will make a much deeper wound if you slip. If you do cut yourself with a dull knife, the wound is more ragged and likely will take longer to heal. Now watch a short video that shows you how to hone and sharpen your knife.
