That is exactly why I do not use any other hones/stones than the Naniwas. I just want to learn one way to get an edge I am able to shave with and not figure out a myriad of different ways to get there. I am lazy and just want to shave.

I will get there to some day.

Being different is very human!

To me the sharpening process is at least as exciting as shaving.
I do resharpen my razors without need just to try some new approach.

I love primitive techniques and do intentionally focus on natural stones.
Also with my other hobbies - wood carving, woodworking, bow making, leather working its all about basic technology, no modern tools, no machines. Just feel with my hands that piece of material is taking a new form...

I love razor shaving cause its that pure and primitive, just put that blade to the face and feel...

Happy hobbying!

Oh certainly, each to their own. You can make things as complicated or simple as you wish.

Philipp, what is the theory of convexing the finisher?

You are just polishing with a smaller part of the hone, really the same effect as using a Rolling X stroke.

I have heard that Dovo uses a convex hone to finish their razors, but it Iis never explained why, and their finished razor are not a testament of great edges, though sometimes close.

I love that you are pushing the envelope trying new techniques, but I don’t understand the convex finisher.

Do you do a straight or a rolling stroke?

Hi Euclid440,
As far as I know Dovo does convex his stones in both directions: from side to side and lengthwise from one end to another, so its a spherical form.
SuperiorShave does explain it in one of his videos. My personal opinion is they doing it for ease of use and error tolerance. Somewhere I‘ve seen how a Dovo-Honemaster was honing a razor on a Coticule, she was wiping that blade with a crazy speed over the stone. I can never imagine that can lead to a good edge, but guess they can achieve consistently 80% of the target in 20% of the time and save money by that.


In my case I convex only shallow hones and only from side to side. Lengthwise my stone are as flat as possible. My hands are not very stable. In 100 strokes I can find myself slightly tilting the razor couple of times accidentally. In case of untilted stroke the razor contact the stone on considerably large line of the edge, the pressure is distributed to all area of contact. In case I‘ve tilted the razor only small part of the edge is running over a very small point on the side of the stone. So consistency of the strokes is low. I imagine that this one tilted stroke brings my edge considerably back if not negliging work of all the strait strokes done before.

Now if the hone has a light side-side convexity to it then regardless of the stroke being tilted or not the area of contact has always the same size so the strokes are much more consistent.
Additionally if the razor‘s edge has a small bend to it or a frown it’s still get in contact with the stone.

The back draw of the convex hone is the higher effective pressure of the edge to the stone (by the same pressure of the hand to the blade) compared to the stone with a flat surface. But there are some work arounds available to further reduce the pressure.

My personal magical threshold is the width of ca. 4cm for the stone. Bellow of it there is a risk of tilting the blade, above I can guarantee a full contact strokes throughout the honing session.

On the convex stone it can still be a straight type of stroke or a rolling stroke, depending on the geometry of the blade.

Regards

Philipp

Btw convexing the stone does allow me working with very shallow stones.
My shallowest is the translucent Arkansas 1cm x 1cm x 15cm, its basically a stone file

A domed hone is functionally just a narrow hone and you’d use one in any circumstance that you’d use a narrow hone. Like frowns and other wonkiness, poor blade grinding so that it is difficult to hone on a flat hone without using the edge or corner (which are also functionally narrow hones).

Cheers, Steve

Perhaps if the Dovo "HoneMasters" would STOP !!! using convex hones we would stop find so many factory induced Frowns on their new razors

Just Sayin

The very idea of calling Dovo Factory honing "Good" is a joke in itself

‘Factory Induced Frowns’

That’s why I won’t buy a new Dovo, yet one vendor maintains that this mis-grinding is what you have to put up with for a hollow blade. And he won’t take a bad one back, he tells you to contact Dovo.

As far as putting up with mis-grinding as a cost of thinly ground razors, may I mention C.V. Heljestrand, Le Grelot, Le Jaguar, Filarmonica, and many American razors ...
