Query: Amazing

This thing is freaking amazing! I was surprised on how good it works! Ive had a few pocket knifes and a few other knifes laying around, used them on this, and man oh man, I swear I could pass it lightly through paper without using much of any force and it would go right through it, and it pretty much did! Left them all pretty much razor sharp, and I wouldn't say to get anything else, get this item if your looking to sharpen up your stuff!
