I find the issue likely has more to do with the incredible amount of information overload a description like this would have. besides weight and sharpness... you also have variable melting points, sizes(including overall size, how many hands, slashing size, blunt impact size, piercing size... etc.), foreign or domestic (better known as "can i make it myself" such as High Boots which may or may not be available to your specific dwarf civ assuming fortress mode), .. ... ... THEN you include the material and congratulations you're looking at multiple pages of information for each singular item.
IMO it's best to leave these things up to the experience of the player / their familiarity with the wiki. Once you know that bone is useless (minus continual hunting bolts but try not to masterwork them), wood is for training (which means now useless as sparring only "taps"), then generally copper-> bronze/iron -> steel -> spoiler with exception to things which rely on weight... you always know it. Think of it as learning to count: I assume you already know that 4 is less than 5 and greater than 3... every time you see a 4 during your average day how often does it tell you what you already know? Instead of 1, 2, 3; think bone, wood, copper.
The same concept applies to armor coverage - it'd be nice to see a quick list on a unit as to which parts are covered by what material, but having all the parts listed on every material is far to much for reason. Again, once you know what things cover (and it's almost completely common sense) you'll always know.
I get the feeling this suggestion is more based off the high count of people asking for advise - when all they would have needed to do was check the wiki; Any experienced Dwarf will tell you to keep that wiki up in the background while you play. You never know what's going to come into your map next, and sometimes it helps to know how to weaponize it. Now I'm not saying anything about adding some more flavor text to the descriptions, that's purely up to player preference.
