I can hear the sirens already. You mentioned "he who's name shall not be mentioned."

Thanked: 1Can anyone please provide links on honing for beginners and which stones to buy for maintenance and honing?

If LvB did indeed hone his own razor as shown, it appears that he did a great job of maintaining its shape. Thanks for posting. Just now reading it for the first time. The stone format seems to be fairly long and narrow. What can we estimate here, maybe 4cm x 20cm? Also, the razor looks like some kind of early 19th-century hollow ground. How prevalent were Sheffield hollow grounds at this time, or during the late 18th century as mentioned?

Well the stone is a little longer than the razor handle and the open box, so I would estiate around 18 x 3.5 (looks a bit more narrow than a typical 7'').
As for the hollow ground, well the old blades were hollow ground to a certain extent (12-15'' wheels) and blades with a pronounced/shouldered spine have been set in quite a bit.
You can find a description in Holzapfel here, with a sketch on page 1148:
https://books.google.de/books?id=fDQ...page&q&f=false
So on the first picture the razor looks maybe a bit more hollow as it is, because of the shadows. But if you look at the second picture you can see that the line of the point is nearly straight, so the hollow can't be that much actually.

Thanks. An approximate proportion of 5 to 1 with the stone in either case. I'd have to see a better image resolution, but it looks like a fair amount of bevel wear, possibly corresponding to spine wear, in Beethoven's razor example. Don't see that in the second example. I'm always curious about how full wedges were honed back in the day. Spine-lifted, as in sharpening a knife? And with mildly-ground hollows like these, were they honed with spine and edge on the stone as a built-in angle guide, like modern hollow grounds?

Well also the honing is widely explained in Holtzapffels description on the following pages.
But I don't think that the people really spent much time and had the routine to hone the razors properly like we do today.
The basic geometry of this very old razors is also different. The spine of modern razors is constant in thickness. If also the lower part and edge of the razor is ground properly and even in thickness and the width of the blade is constant, that secures, that you can hone the razor properly over the hole length if you lay it flat on the hone.
But thickness of the spine of these old razors mostly varies. They are getting thinner from point to tang. That means if you really lay it flat on the hone the angle of the cutting edge changes. To balance that a bit, the blades are getting generally wider to the point. But together with the fact, that you had mostly very narrow hones at that time, the honing wasn't equal over the total length of the blade, which led to uneven honewear. And that is why you see a most of the ancient razors having a lot of hone wear at the beginning of the edge near the tang. At this point the spine is substantially thinner than at the point.

Thank you for your informative descriptions, and for referring me to the passage on honing in Holzappfel's treatise. On page 1153, I read the following: "The blade is grasped in the right hand by its tang, and near to the cutting part, and is placed square across one end of the stone but tilted about ten or twenty degrees, and is then swept forward along the stone, edge foremost in a circular arc, so as to act on the entire edge; . . ." This "tilting" I take to be a lifting of the spine.

I see. That could account for the narrow hone too.
