I like DMT and still want to get my grubby paws on them! Good quality and you can sharpen anything on them, especially these new harder "super" steels.

I have seen the sharpener before on BF and though I think it is "cool" I just dont like it. As wrxguyusa said. Sharpening makes me relax and I enjoy sharpening my knives. This takes that aspect away from sharpening. Still will buy it to get other peoples knives sharp as it will be faster then by hand and most people screw their knives up to such a degree you need a power tool.
