Silver maple is right up with Box Elder (Manitoba Maple) for toughness and durability! I don't even think it qualifies as 'soft maple' with is usually the firewood/woodworker term for Red Maple. As opposed to 'hard maple' which is the general moniker for Sugar Maple.I have a bunch of silver maple but it's probably only hatchet handles and such. I'd like to find a suitable piece of hop-hornbeam to try out. I found a nice piece of ash (heh) at the lumber yard. Three inches thick, ten wide, and has grain running the right way. It's flat sawn but pretty close to quarter sawn orientation. There's enough there for a few handles. I'm thinkin' it might be something to occupy my time this winter.
If ever I find a good slab of Ironwood at a mill I will alert folks on here. If it's a small trunk you want that I can come up with that easy enough. It has to be sawn, I have never been able to split the stuff. There are 2 types and equally tough; Blue Beech and Hop Hornbeam. Blue Beech rarely gets beyond a trunk diameter of 4 inches whereas Hornbeam can be had up to about 12 inches.
