Re: [ATM] Tile tool x diamond pellets

Thanks. Maybe we'll use it for a trepanning job later
on. Definitely need to test it out.
Seems to me that there is some characteristic of
diamonds that allows miners to catch them and leave
behind all of the dross and ore, somehow; we should be
able to use that to recycle and recapture the diamond
dust?
