I'm getting more and more confused the more I read. Is it about 22 degrees per side, giving it an overall angle of around 44 degrees? Or is it 11 degree per side, giving it an overall angle of 22 degrees? I use to think it was around 40 overall, because that's what most knives are sharpened at for a durable working edge, but then I though about it and it just doesn't seem right for a grind with no secondary bevel. So which is it?
