It seems you nearly all use weapons that I just haven't gotten around to trying yet, lol. My character is usually armed with a one-handed sword (Themaskene Steel Spathion) to go along with the shield I mentioned earlier, and for extra fun I have a two-handed sword (Justicier) slung on the back...the two-hander gets used during large field battles when I want to go after enemy lords and cut them down off their horses.
The sledgehammer intrigues me as a choice. A repurposed tool and readily available early. Seems like it would be satisfying to use...nothing like a big hammer to deal out punishment to troublemakers. Again, never used one (but inspired to try it out), but I do sometimes use a mace (currently, Imperial LIght Mace) of some type when I'm going to be chasing Looters that are running away so that I have a higher chance of taking them alive as prisoners if I can hit them.
Haven't been using any spears or polearms, except in tournaments. Like the idea of maybe using something like the menavlion from horseback as a lance when charging, if that would work well. Did during beta some time back, had fun with watching riders I would hit in it go flying way up in the air after riding headlong into them with a long spear (but maybe they changed it so it is less spectacular-looking now).
Javelins, too, I have only used in tournaments. Some future character may use them more.
While I haven't really gotten into axes recently, I do have a Black Heart in my stash that I won in a tournament awhile back...maybe my character's successor (if I get that far) will use that. As I am not playing as a Sturgian and most likely will not be changing sides, I doubt I will get anything better this game unless I happen to find something nicer for sale in some corner that hasn't been checked yet.
Gear...my current character is with an Imperial faction, so most of the things they wear and use otherwise are Imperial. Have some Legionnaire armor that I bought. Many other items are looted or won and used because they are solid armor, so there are some pieces that don't match the overall look. For civilian clothes they wear a toga and carry a nice spatha. And I have a mount that I'm pretty happy with, a Wadar Hotblood...prized for it's speed, gets me around battlefields pretty quickly when I need to be quick about things.
