Has anyone out there tried this sharpner ? If so, how do you like it. You can see it at www.graceframe.com. Would like some input. Thanks in advance.

I don't use a sharpener. I just buy replacement carpet cutter blades at Harbor freight for $1.49 a pack for 2 blades and they work on the 45mm rotary cutter.

If this is the electric one, I recently got one and I am happy with it.
The one thing I don't like is that it is unusually LOUD. I have read several other reviews that say the same thing.

Other than the noise, I think it does a decent job of re-sharpening a blade. I don't wait until the blade won't cut anymore. I sharpen it after every big cutting job. It isn't "out of the package" sharp, but it is close.
