Edge angle on a splitting wedge

[Malpaso]

Found an old splitting wedge, rusted and not much of an edge to it. Going to try to make it usable. It's Chinese steel, so it will be good to practice on. What angle is the edge usually on a wedge? The only info I could find was 45*, but that seems too severe.

Personally I make it a blended convex like an axe. I'd estimate about 15° per side with the edge shoulder knocked off and rounded in. Blasts through wood compared to a normal off-the-shelf geometry.

There is a thread on this somewhere on this forum...

We've had some good discussions here about wedge grinds. I suggest you read them. 42Blades and I amicably disagree on whether the final edge should be concave or convex. But we agree generally on grinding wedges much thinner than the ones you find at the hardware store.

I'd guess that somewhere in the general ballpark of 30 degrees would be a good place to start.

The good news is that the metal is soft and wedges are plentiful so it's a good item to experiment with.
