You're right, physically speaking. But for the purpose of a game model, it's important the edges aren't too sharp, or else it'll bake badly when I'm making the normal map.

Thanks, Bullet and David. Good to see you guys again!
Thanks guys! Stwert, yes, there's a bit of faceting, but in a game, where this takes up only a small part of the screen, and mostly from behind, it shouldn't be an issue; and if the enemy were using it, it would never be close enough for you to see anyway.
Tweaked the wood a bit, to differentiate it from the metal. Added some damage to the wood, &c.
