#2 If it works so well why can't the "Masters" in Solingen honing every day manage to produce a Shave Ready edge,and actually now on Dovo manage to produce frowns

Kinda defeats the logic of the arguments now doesn't it

This thread is more about the fact that it isn't just some idea out of the blue and has real historicity. Not really interested in the practical claims anymore it's been beaten to death imo. We'll all believe what we want to believe at the end of the day and that's totally fine.

In English

"The main thing always remains that once you have straightened your razors in good condition and especially with a sharp edge, if they have suffered too much from prolonged use, it goes without saying that you should hand them over to the sharpener for repair

Sharpening the knife is apparently something very easy, but only a few understand it well most of the sharpening their knives is not flat but convex so that the cutting edge is sharp but at the same time wedge-shaped, which means that the advantage of a thin, hollow-ground blade is lost again, that's why it's here Probably in place to deal with this subject in more detail"

In German

"die hauptsache bleibt immer dafs man seine rasiermesser wenn sie einmal bergerichtet sind in gutem zustande und namenlich bei scharfer schneide erhalt wenn dieselben durch anhaltenden gebrauch zu sehr gelitten haben so versteht es sich wohl von selbst dafs man sie dem schelifer zur wiederinstandsetzung ubergibt

das scharfen des messers ist num anscheinend etwas ganz leichtes aber nur wenige verstehen es gut die meisten schleifen ihre messer nicht flach sondern konvex so dafs die schneide zwar scharf aber zugleich auch keilformig ist wodurch der vorteil einer dunnen hohlgeschliffenen klinge wieder verloren geht est ist deshalb hier wohl am platze diesen gegenstand etwas eingehender zu benhandeln"

This topic and to tape or not tape a spine while honing have been done to death on this forum. Choose which ever way you want to do it from the copious amount of info on here already. It really does not matter a whit which one goes with so long as you are getting the results you want.

You can't sell stones and "special" lapping plates if nobody wants to talk about it.

Nailed It ^^^^^

You might want to re-read this part again... I think you are missing it or your translation skills are lacking

This part too

Others go even further by giving the successive stones a different shape. In particular, an experienced man praised the following procedure as being very beneficial:

The translation is what came through Google Translate and some weak German I learned in highschool over 17 years ago. Yeah it ain't perfect but it paints the picture. You can take the translation literally if you want but that would be erroneous.

Who would you assume the 'experienced man' is being referenced in a Journal for German Technical Schools?

At the end of the quoted text: "he latter is found exclusively in use by knife manufacturers, knife sharpeners and barbers."

The Germans refer to a razor as Rasiermesser, literally razor-knife. I doubt the previous paragraph details the sharpening of razors until right at the last sentence when he suddenly switches to talking about kitchen knife makers.

There's enough here with my crappy translation to believe the idea wasn't invented 5 years ago.

Again everyone can make their own mind up. All the passages I'm translating are linked to and people can adjust as they see fit. If there is something wrong with my translation I invite you to correct it.

Here is the issue

Looking at 1000's of Dovo edges over the years shows none of this to be true , they simply lift the spine then drag it over the Convex hone creating a Frown

Over 60% have it

So the science falls apart in reality

I don't know or care who the Gentleman is

This has truly become the "Epitome of Stupidity"

There is one person pushing this for money, I wouldn't care other then that little dweeb involved me after I proved his "Hypothesis" to be flawed, and he started tagging me for Hits on YouTube..

I don't care who posts about it... I am going to continue to say the same thing

Prove It !!!


I have yet to even a Micro-graph even attempting to convince anyone of Concavity of the edge

Again this thread is just documenting evidence of the fact that this way of honing was something actually done in history. I really don't care if the edge is concave or not tbh. First source actually claimed it was to reduce honing time. What Dovo does or does not do has no impact of these texts which are over 100 years old. Jarrod has many flaw I'm sure but I doubt money grabbing is one since many a time I've asked him about this topic he basically tells me to go get a lobster pot and make a convex hone myself. He doesn't sell many stones anymore either. More likely a dog with a bone mentality than anything else. Maybe I'm naive.

Once again

Prove It !!!

You have simply revived Controversy much like Tape vs No Tape and GD razors

The same circular BS

Show us the edges you have honed on your Convex hones, lets see them, hopefully they don't have huge scratch's all up above the bevel like Jarrod's showed.."
Your first foray into this I gave you the benefit of the doubt as being naïve, however now it seems you just like to stir the pot..
