Stretching the power tools definition a bit though...
This IS a power tool. I use this to sharpen the knives - more important than the RC rating is maintenance:

Yeah, I know, not really a power tool, but damn powerful ;D
I should have posted a pic of cordless Bosch GSR...something screwdriver instead, but my knives are way cooler.
I hope you don't let your knives get warm on that thing, could easily ruin the tempering and render HRC to below 50.
I only uses water stones and a leather stop, but I'm most defintly a knife geek.
BTW that Kai Shun is rather good, perfect wedding gift. I have one of their 8" chefs knives but I left it at my fathers place since his knives were made out of garbage cans lids.
The knives on my pic are:
Suisin Gin Momiji 210mm
Hiromoto AS 270mm Wa Gyuto
My favorite tool (also most necessary tool for work) is my Husqvarna 576xp chainsaw. **So clean looking because this is right after I bought it**

That's a really nice chainsaw.
