I'll chip in on this one. Most of my work is cabinet making so I'm grinding the primary bevel on chisels and plane blades. Some years ago I tried a Pro-Edge and hated it; you simply cannot grind a blade almost to the edge without the imminent possibility of 'blueing' the steel and at £60 a pop for a Veritas/LN plane blade, it's not worth the risk. The Tormek, though expensive, is water cooled so I'm able to grind to within a fraction of a mm on the edge, with absolute certainty that the steel is still good. I also fitted a coarse diamond wheel with completely transforms it's use. Downside is of course, that it's slow, especially to re-shape a profile, but with the right jig, it's a matter of seconds only to re-sharpen a gouge. That said, all gouges and turning tools these days are made from HSS which will tolerate a degree of 'blueing' without loss of temper. As ever, horses for courses and what suits one won't suit another, but if you're after the best and safest option for all your grinding needs, the Tormek is a 'no brainer' - Rob
