    Default A different slant on honing

    Saw this video posted on another shave forum. I thought it interesting enough to post it here as it departs from what most of us have learned to do.

    So, consider the source.

    Why not just strop on paste and get the same effect? A sheet or two of copy paper under film does the same, provides a bit of give to convex the edge.

    Yes, nano grit paste, CBN or Diamond can yield a great shaving edge, but few razors can handle that edge and microchips after a few stropping’s.

    Consider the source.

    So if im understanding this, we need to use a convex hone and not flat? In my mind if you could make a proper bevel this way the edge would be thinner which also wod make it weaker and not last as long. We are talking microns here so Im not sure it would make a difference.

    Enteresting but I dont think Im going to change the shape of my hones.
    It's just Sharpening, right?

    I did not post this to promote the technique in the vid but to stimulate conversation about it knowing it would be a controversial subject.

    Not sure, a photo of a drawing of the plate he is hawking looks concave.

    This is the same guy that gets sauced while making videos to promote his company. A few month ago, he was promoting the opposite.

    Maybe he was a bit Scotch challenged, read the comments under the video. Issues?

    The plate is for producing or maintaining the convex hone

    Sorry, I didn't watch it all - I gave up at the first diagram when I couldn't see what "A" was.

    Blade geometry isn't rocket science. Neither is removing metal from an edge to meet in a finer and finer point from both sides.

    As far as convex and concave "grinding surfaces" go, what matters is the radius of the curvature - if you had a large enough wheel, for example, a 5/8 razor wouldn't know it was sitting on a curved surface at all. Similarly for a dished stone - if the radius of the dishing is such that you are talking 1 micron lower in the middle of the stone to the ends, is that going to matter? Can anyone guarantee their stones are completely flat? To what tolerance?

    Anyway, I applaude the effort but IME these kinds of videos, while couched in terms of generating discussion, are usually being made by someone with something to sell. Apologies to this guy if I am wrong, I have no idea who he is or what he does.

    James.

    Maybe, possibly, factories use / used convex hones and not flat stones because it saves on lapping. Honing hundreds of razors would need untold amounts of time just for lapping..

    Are razors really honed by hand in the factory or are the honed on some automated spinning wheel? I guess I just imagine the modern razor factory have conveyor belts of blanks cruising along between finer and finer wheels before coming out honed and stropped on the other end before some robot peens scales on them.

    If you're wondering I'm probably being sarcastic.

    I think its Dovo have the spinning wheel and then onto the large Coticule.. TSS has a video showing this.
