That’s a good idea. Never thought about it but gleam could be fragile enough so you can break it.
Alternatively, the idea I posted in another thread.
I’d be ok with both solutions, as both are far more realistic then punching a tree with a fist/stick^^
Maybe a combination of both. Punching leaves for sticks and gleam for shards. Craft both together to get a crude tool with which you can chop down trees.
