Thank s for the advice. I actually watched your YouTube video when you used blade pressure to hone a Kamisori with an uneven bevel. Do you ever remove metal from the spine in a bevel set? And what circumstances would lead you to do this?

Same here, there has to be a drastic reason not to use tape. i learned my lesson very early when i almost wrecked a blade. it's impossible fix once you go to far Originally Posted by gssixgun

Nothing on the spine will ever keep the edge from contacting the hone - and nothing else matters. You can increase bevel angle/reduce bevel width if needed by adding tape, but the evenness of the bevel is dependent upon the surface of the blade. If the surface is uneven/irregular, when you cut a plane through it by honing (the straight line between the spine and the edge) then the bevel will be irregular. Period. The only way to have a geometrically perfect bevel is to have a perfect blade surface in perfect alignment with a perfect edge and perfect spine. Of these elements, the only one that matters is the edge - and it will be made perfect when the bevel is set.

Here is an illustration of uneven bevels borrowed from Coticules.be:

Regardless of the bevel being of even width along the blade or varied/wavy width along the blade, so long as the bevels meet all along the blade the razor will shave because the edge is set.
An uneven bevel is mostly a cosmetic issue indicating one or more issues/faults with the blades geometry.
