So I've got a set of Cutco knives that I've used a Sharpmaker to keep up. I just added a couple of Rachael Ray Furi santokus to my cook's arsenal, and they recommend (of course) their own sharpening system to upkeep the blades. They mention that the blades are ground at a 20 degree angle. Some of the comments I read about the quality of the knives before purchasing them raved about the razor sharp edge...I was not impressed myself. I keep most of my kitchen knives near shaving sharp...paper thin tomato slices baby!

Anyhow, I was about to replace my Sharpmaker...lost mine in the Midwest floods. But this system that Furi offers costs about twice as much and if it only maintains a 20 degree angle, instead of the 30 or 40 degrees the Sharpmaker does, then I'm buying two sharpening systems...

Or I may look into an EdgePro instead of either of the other two...

Will I ruin a 20 degree blade with a Sharpmaker? Buy the EdgePro instead? Get all three?

Funds are limited due to the massive personal property loss during the flood...
