"double talk couching babble"

We're just misunderstanding each other, nothing sinister in it. I went as far as talking to Glen on the phone for 15-20 minutes tonight since I felt things were...

You're making it sound as if I'm advocating the convex hone, I've stated multiple times I don't think the supposed advantages would translate to the real world. That doesn't mean the theoretical...

Honestly I think your high feelings over this issue are making you take my comments out of context.

Look there is a difference in whether a convex hone would prescribe enough of an arc on a razors...

This is extremely uncharitable.

My claims actually back up your general point that a concave bevel isn't a real world advantage.

My proof is that I calculated the distance of the saggita from a chord which measured 0.5mm across a wheel that had a diameter of 7600mm (25ft, the same kind of radius as a convex hone) The distance...

You're rolling all the claims into one. Here's how I see the claims:

1. Given all things equal, the a razor honed on a convex stone creates a better edge for shaving than one formed on a flat...

I already stated earlier that the amount of concavity imparted on the bevel was imperceptibly small. Could anyone, given all other variables equal apart from hone convexity, feel a difference? That...

It's all about the theoretical advantage versus the real world benefits. Maybe the people at Dovo are very focused on the supposed theoretical advantages and just assume that translates to real world...

Yeah this is totally fair taking three words out of context.

Well none of us has, or will have first hand knowledge of whether convex hones were used say 100 years ago. However, there is obvious visual proof that some razor manufacturers use them...

We're just talking about rocks man.

I think you're reading my responses in an uncharitable fashion.

I've been respectful and kept an open mind throughout.

Any assertions (ie, that the...

Which is a distinct issue in itself aside from the use of the convex hone. Maybe the convex hone makes it easier to cause a frowning blade for someone who isn't a great honer. Seems entirely...

I'm not making any assumptions. Literally almost every post I've made has words like theoretical in it. The assumptions are made by others that I am referencing in my posts. I have already stated...

You can overhone the middle of a razor on a flat hone that is sufficiently narrow.

I think it is the convexity down the length of the hone which provides the supposed primary advantage of using...

If honers in Solingen have been using convex stones for the amount of time we are told, which I have no reason to immediately doubt, there have obviously been many razors made in the past that were...

I can't say much about Dovo current production standards as they are right now. I have one Dovo I bought a decade ago, it shaved well when I bought it and had no frown issues. There do seem to be...

You tip the blade as you make the strokes like a rolling x.

I was making the point that most edge tools were always traditionally ground towards convexity, which may or may not have informed past peoples ideas about ideal edge bevel geometry on other, more...

Wondering if you could drop some links or whatever to some literature on this. I've never come across anything that specifically addresses the shape of the edge bevel.

I have some pages from a...

One can agree with all the theoretical advantages of a concave cutting edge whilst questioning the real world advantages. It is certainly true in a physical sense that an edge that is honed on a...

I imagine the bevel is concave but to such a small degree it wouldn't really make a difference. Something probably measured in microns. Concave bevels in themselves may have some theoretical...

Was a typo actually meant frowning blade.



This is surely true of most hones regardless of convexity.



I agree.

The convex hone thing goes back a long way so I don't see how that is the issue, plus sloppy honing will create a frowning blade even on a flat hone. Maybe the convex thing is one of those academic...

We've all got to remember that the pinnacle of straight razor manufacturing has come and gone. When you had dozens and dozens of companies about in the 19th and early 20th century making blades, you...
