The accusharp has been round for generations for a reason. Simple to use, and brings knives back to life within a few swipes. The blades are reversible, so you get two lives out of it. Then, when they finally wear down, you can simply buy replacement blades and insert them yourself. This way, you are never paying to replace the unit again.
Great for: Kitchen Knives, Fishing Knives, Hunting Knives, Sporting Knives and more!
