Hello, I was curious to know what the bevel angle is for a de blade. I know there are many makers and Im sure it varies. I have heard straights are 15-20 degrees. If this angle was made shallower, what result can you expect? Or would the edge be too fragile? Too sharp or rough to shave with? Curious if anybody has any info. And I guess the only way to change the angle to be shallower would be to grind the spine and not the edge. Thanks.
