Anyone know the angle of RC-4 secondary bevel?

Hello all,

Just wondering if any of you know what the angle of an RC-4's secondary bevel is?

is there a secondary bevel?

If you mean the edge, it is approx 20 degrees, 40 degrees inclusive.

They are, however, sharpened by hand, so there will be slight variances.

All of mine are really, really close to 40.

sorry, could have added that. It says so on the booklet that comes with the knives. 40 degs inclusive (equals 20 on either side).
There is no secondary bevel as far as I can tell, only one angle for the whole edge surface.

Well I was talkin about the cutting edge. If I mistook it by calling it a "secondary bevel" I apologize. I did mean the cutting edge.

Thanks for the responses.

I went 20 then 25 for the edge.
