Okay, I don't know about the equipment but. I took my mom's kitchen knives and kitchen shears on. All of them were pretty much duller then a spoons edge. I got them back (the girl found me in one of the ailes I was browsing in) within 30 minutes. I am impressed with the new edges they have on them. My mom is extremely happy, so I'm happy. Will go back to browse some more but with my wife next time.
