Thread: Question on consistency of bevel across the razor.

There are two things that affect the shape of the bevel - one is a distorted spine and the other is the accuracy of the grind - blade geometry i.e. the spine width to blade width and the extent of hollow grinding affect the bevel width.

If a razor has a distorted spine you will tend to get different bevel shapes either side - one side may be wider at the ends because the middle of the blade is not touching the hone as much - the other side will display the opposite. An experienced honer can overcome this to an extend by using a different honing action and maybe tape.

The fact that your razor has a straight bevel on one side suggests that the spine is also straight - so why would you get a wavy bevel the other side? The answer could be that the accuracy of grinding is not so good on that side - if there is more metal in some areas this will produce a wider bevel so the fact that your bevel gets very thin in the middle suggests that it was ground a little closer than the ends.

When you look at bevels under magnification, very few are perfectly uniform but it doesn't affect performance so long at the bevel is set properly.
