Ten minutes would include reprofiling of the blade, then the actual sharpening and a final buffing. I don't see how, even free hand it could be done in two minutes, nicely.
And actually how does free hand buy any time? It takes all of 10 seconds to attach the clamp and another 15 to adjust the angle guide and then its back and forth in what could only be described as the motion that would be used free hand. And unfortunately, in my experience it takes longer than two minutes to sharpen a knife. Although the stone can be used to take material off, its kind of like the Spydeco ceramic stones. Not really aggressive and they take some time. No matter how hard you press, it takes time.
If all you want is a free hand wheel go and buy a grinder and put a couple of different grit stones on it, or a belt sander is what most of the makers use and it would be a real dual purpose machine and probalby save you a couple of bucks. But you won't find a better stone for finishing or you won't find a grinder or sander that runs at the low RPM's as the Tormex. The Tormex is made specifically with an angle guide and jigs to make sure that the edge is perfect to what ever angel you want it at. If you want to be a purist and go free hand this is not the machine to buy. Go and get a couple of good bench stones and have fun.
