Really?
The whole thread of discussion on weaponry, and not one mention of my favorite?
I assume you have miners, and I assume you have... soil, giving a pick of any quality to a miner and having them clear a bunch of soil or even stone if you have longer to work with, will rapidly raise their mining skill, then disabling the mining labor and assigning them a masterwork pick--yes even copper if it is all you have, but a steel or candy pick is a helluva thing--gives you two things: living area/farming area/stones possibly, and a delimbing machine of gloriously simple effectiveness.
A legendary axe dorf can slap a goblin upside the head with the side of their axe or bash them with the handle until it finally dies of boredom, though they do love to send limbs flying, they tend to waste a lot of time and effort on the useless "flourish" options... I can't think of any situation where I would want to slap someone with the side of a battle axe, even a shield bash makes more sense.
A sword dorf with great skills and a steel or candy masterwork will also let you play "now where did that head end up landing" all day long if you want, plus sometimes they'll stab things in the heart, and sometimes they will slap something around the map with the side of their sword for a day or ten... makes more sense than the side of an axe, but still dumb, even for a dorf.
A legendary miner with a pick only knows how to do one thing: dig, and if all you've got is a pick, then labels like "goblin skull" or "forgotten beast hide" are as unimportant as "granite" and "galena" to a newly drafted miner.
Honestly the only difference is rocks don't usually scream... or bleed... or cry for help... or breathe poison.
