Well, correct blade bevel angle is a bit of a tough one with a #4. In a bench plane like this the bevel is down so the bevel angle has no bearing on the cutting angle. The iron angle is 45 degrees with that plane. So, I tend to use a 30 degree bevel with about a 3-5 degree microbevel to make honing easier and faster. The cool thing about a 45 degree blade angle is that you can incorporate back bevels into the iron to gain steeper cuts for different planing situations. As I don’t particularly have a great understanding of those situations, I go with the 30 degree primary with a microbevel as stated for honing ease. I believe that, based on what I’ve read, that 10 degree of relief is pretty much a general purpose angle. Now, my answer is based on things I’ve read and I make no claims to be a hand plan officianado. I use them with delite, but with a healthy dose of awe and wonder. I sharpen everything with jigs in order to maintain the bevel that I’m familiar with.

I hope that helps a bit. I’d wait for Wayne to chime in here though!
