In John Juranitch's book on sharpening, which I read recently, he says: "...the Missus had the uncanny ability to tell if a knife was sharp or not. She very simply "thumbed" the edge by letting the knife edge cut into her fingerprints to a point where you could see the cut, but where it would hardly reach the base of the print. In this way, she could accurately grade an edge." I had a shock of recognition at this -- I've been doing it for years; it's how I judge an edge. I can tell you that this technique has a fatal flaw -- if you run an edge through a previous groove, you will definitely bleed, if the edge is worth anything. But my point here is that it's more than just sharpness that my much-abused thumb sussed out -- it was a genuine affection for one steel over another, based on the feel of the edge. It's not just an affection for a good edge. VG-10 takes a good edge, but feels just a bit numb. S110V and Maxamet take really formidable edges, but feel impersonal, hard, distant, almost ceramic-like. My first affection in this area was Blue Steel, in chisels and plane blades. Something about that edge spoke to me, and led me to seek out knives in that steel, whose edges I liked just as much. I thought that was the end of it, but then I discovered M390, whose edges I may like just a bit more than even Super Blue. Does anyone identify with this? If so, are there other steels that inspire this reaction for you?
