UPDATE!!!!
So I am paired up with a new mechanic at work, and the other day while working on an elevator we needed to open up a box, so my partner pulls out a Buck Stockman, ( i love these knives) and goes to open the box. NADA, i have butter knives sharper than this. I don't think it was sharpened in 10 years. So I take the knife home, and NO JOKE within 10 min I have all three blades hair shaving sharp with this sharpener. Very Very affordable, and unbelievably effective. I have one in the truck, one in the hunting pack and one in the kitchen. Do you self a favor and pick one up.
