Who needs a portable knife sharpener?

The answer to this is quite easy. Anyone who prefers to carry a pocketknife should also have a portable knife sharpener that they can take wherever their knife is needed. Sometimes people prefer light and pocket-sized knife sharpeners because it gives them more control over refreshing their sharp utensils. Another reason for buying a portable knife sharpener is when you don’t have enough space for a bigger model in your kitchen.
