I think more info is to come. However we may not get specs. This appears to be a custom version of a nano fusion steel heart. A Google search of Busse nano fusion steel heart specs. Will get you an idea.
It’s fun ain’t at! Nice blade you got there. I feel so much more satisfied after beating on these Busse blades. I try not to baton over concrete myself. Hope you didn’t have to pay for concrete repairs to the campground.
