Interesting article. Schwarzy concludes that Studley would say as follows:
1. I like a convex bevel. Nearly all of the edges I observed had a slightly convex bevel. A couple tools had evidence of a hollow grind in the middle that was in the process of being removed by sharpening the bevel (making it convex).
2. I like cambered edges on my planes. Nearly every edge of the plane blades (blocks, smoothers, jacks and try) had a cambered cutting edge. Many of the edges were significantly relieved at the corners.
3. I sharpen the entire bevel. Only one tool had any evidence of a micro-bevel.
4. I lap the backs of my irons and chisels. All of the tools in the chest have lapped backs. The lapping is not to a mirror sheen, but there is evidence of significant and continuous work on the backs.
5. I lift my plane irons slightly when I polish the backs. Over and over I saw evidence that the very tip of the back was polished to a higher degree than the metal behind the tip. And (using a machinist straightedge) I could see that the tip of the back was ever-so-slightly dubbed from this polishing. The polishing on the backs was heavier on the bevel-up planes than on the bevel-down planes.
You can take the above information and twist it however you like. Studley was a hand-sharpener. He sharpened the entire bevel. He did something similar to the ruler trick – though he probably didn’t use a ruler. He knew that he needed two intersecting surfaces to create a sharp and durable edge.

Pedder basically beat me to it. Messrs. Studley and Seaton are known for their chests of tools. Where's the furniture? A whole lot of guys are going to kick the bucket and leave a beautiful collection of tools. Few will leave furniture remembered by later generations.
Fellows are laboring over projects (me included) that take dozens of hours to build, you know - the ubiquitous and at the end of the day basic bit of woodworking/rectilinear monument to the one-trick-pony (three months later: look Ma, no gaps!) that dovetailing has become - projects that would have been completed in less than a week by our forbears with a big yawn. Cutting a single joint well has become the well-trodded path to internet fame if not a way to earn a living for some. I think the antidote to all of this might be making a pair snowshoes, yeah, that's it - I'm going to make snowshoes! :lol: Or maybe just a little mindless turning of a chair-leg at the lathe, just sketching really, sketching in 3-D, looking for a shape, a new combination that pleases the eye. A lowering of the blood pressure rather than the raising of production of yet, another, rectangular, box, project, of, some, sort, small, or, big, take, your, pick, (hands moving down the keyboard playing loud, minor, chords). Blech. And more blech.
Back on track - a slight bit of a back bevel is not a deal killer nor is it the woodworking equivalent of the Rosetta Stone. It is certainly not worth all of the virtual ink that has been spilled discussing it. And of course a wisp of a cambered edge certainly beats pesky plane tracks. All of this should be kept well between the ditches of course. Truth, like woodworking best practices, is rarely found at the extremes. All of these little bits of curvature here and there should take on the subtlety of a mistake - when they look purposeful, or are achieved by the tenacity of purposefulness, they are almost always overdone. An artfully executed slight error is what's needed.
File it under "How did Alan Peters hone?" That's probably the way to do it. 'cept dear Alan didn't leave behind a nifty tool chest full of cleverly packed ebonied gear (or at least one that is famous at this point), apparently just a few Record planes (who wouldn't kill to own his trusty No. 7?). But, oh, the furniture![/quote]
I promised myself Iwouldn't get dragged into this one, but what the heck. I was very lucky in being asked to help with the dispersal of the late, and very great Alan peters tools. Some people would be very surprised at the diversity of Alan's hand tools. Most of it was very basic, and there was no high end shinney stuff. I don't know what Alans preferred method of sharpening was, but I do know this much. he was a full time proffesional woodworker, and his kit was sharp!, but if you had tried to analyze how he actual sharpened his tools, you would be struggling. There were concave bevels, flat bevels, and yes on occasion the odd convex bevel!!. A lot of the chisel handles had masking tape wrapped around them, presumably to give them a more comfortable grip. As to his trusty number 7, i'm afraid it met a sticky end a long time ago. he dropped it, and smashed the casting. He replaced it with another one that was made up of a mixture of Record, and Stanley bits. I seem to remember that the front knob was beech, and the rear handle was rosewood. Of all the kit that I sold off for Alans wife, I only bought one piece for myself. It was the tattiest beech marking gauge you would ever see, but it works like a dream, and to me it's priceless.
