I was a little skeptical on buying a sharpener because I'd read mixed reviews that they don't work all that well. Well, I'm here to deliver the verdict. If you've ever had a prior judgment of handheld skate sharpeners, or any kind of skepticism regarding them, I can assure you this product in particular will make you do each of the following in this order.1) Roll all that skepticism into a ball2) Buy golf tees3) Take out your driver4) Tee it all up5) Make sure your feet are square to your target6) Blast that bad boy into oblivionProduct is legit. Buy it. Use it PROPERLY (slow with a lot of attention to making sure that the sharpening stone is flat on the outside of the blade.. this is imperative). You must use the stone in the same direction on each sharpening stroke. Then finish it off with the other side by dragging the ceramic over the top of the blade in the same direction.
