I have sharpened with stones and gadgetry to bevel evenly. I have taken quantum leaps by buying the paper wheels and within 1/2 hr. of practicing, I was sharp enough to remove a patch of hair from my arm. 2 steps, grit wheel raise a burr both sides, and the "strop" it off with the slotted wheel. As my hand trained and I got better, my knife edges will catch a hair dangled in mid air and slice up the hair (whittling) it. This is my highest achievement in sharpness so far, and has quenched my thirst of trying to get sharper than that. It really is that quick, and is a solution for right around $100.00 I would award it the "most direct path a novice knife sharpener can take to get professional sharpness," award. I envy those who can free hand and achieve that sharpness or greater. I am sure knifeknut does amazing work and I will take his opinion to the bank everytime. I resisted the paper wheels out of my own ego wanting to become one with my stones. I am glad I got over that. I am a razor sharp paper wheel fan boy. I get my knives razor sharp in conflict of what others say. I can dry shave my cheek with my knives and I have neanderthal like facial hair. There is no irritation. My advice is to sell all of your other gadgetry and buy a grinder motor and a set of paper wheels. There is nothing complex about the paper wheel set up.
