whoookay, here goes.
Let's start with the easy stuff. First off, there's a reason double sided maces don't exist. They'd be too heavy and too short to be wielded in any effective manner. If you want something like that, a staff with weighted ends would serve the same general purpose. I'm not entirely sure why it has hooks in stead of regular spikes or being a bladed mace, either, if you could elaborate, that'd go a long way to an approval. If the intent is to hook opponent's limbs, then I'd suggest an axe, as that's a weapon that has historically been used for such things. in addition,. not sure why or how he'd use a mace for carving when he seems to have proper tools, but that's just me and doesn't actually effect the approval.
On to the more....complex things. I'm not sure how this scraper works, but it doesn't seem like a conventional rock tumbler, in that it uses metal blades rather than grit sandpaper and powder, and that it can apparently easily shred a metal hand apart. So I'm not too keen on that.
Good at hiding is sorta subjective, and I'm iffy on it, but if demonstrated properly I have no issues with. key word being properly. I expect research to be done.
Demeanor of a toddler.... What does that mean? Why is it there? You've already described him as friendly, and having an overall good demeanor. Was childlike the word you were looking for? Because toddler to me at least brings images of temperamental, mood swinging small children. Not that all toddlers are temper mental or moody, but the wording is just..... odd.
Being good enough to hide from fifteen separate people for over an hour? Noooot gonna fly. also iffy on that being enough to level him, given that from what I'm gathering he just..... stood really still and blended in somewhere for an hour?
In all, Tombstone is not approved, and needs some serious work.
