It is the best sharpener I've ever purchased. Used it to re-sharpen a hundred dollar set of steak knives, they came out sharper then the original, and I was ready to throw them away. Also sharpened a few garden tools, they are better then new, it's a keeper!
I have waited a long time for a versatile blade sharpener. This little guy seems to fit the bill. I wanted to resharpen my Felco Pruner blades, but found all the other sharpeners too clumsy or inadequate for the task. This sharpener can, with a little bit of contortion, resharpen a Felco blade while in the pruner. For best results, I would recommend removing the blade and sharpening it separately.
My guys are always asking for files to sharpen their pruners and knives. Well once I purchased this machine no more files and they love this machine.
