Okay, this isn't an art thread, but if you can provide an image for the weapons, that would help show others your idea. 

This thread is to share ideas, mechanics, and images for race-specific weapons that you have in your D&D campaigns. For example, here's a dwarven club/mace weapon that someone on reddit created for their campaign. (I recommend checking out the first comment for it. It's great.)

Another example would be the Double-Bladed Scimitar from Eberron, or the Gythka and Chatkcha weapons that thri-kreen have access to in the Monster Manual.

So, what race-specific weapons do you have in your campaigns and settings?

Not my campaign, but in Mystara, at the heart of every halfling shire is a Crucible of Blackflame: a small wooden pyramid holding black fire from the Nightmare plane. It leeched heat and light from the air around it, the reverse of a normal fire. If I’m not mistaken, it slowly dripped Oil of Moonlight, which over time the halflings could work into fabric to make it fly when beneath the moon, creating flying sailing ships and whatnot. It also gave special powers to its keepers, and could even be worked into items. Anyone but a halfling who touched it or those items took severe cold damage.

Cool. Do they make weapons out of it?

 Yes, Blackflame even “burns” rock, so “lighting” stones with blackflame makes for potent ranged weapons. Only full blooded Hin were immune to the icy burn of blackflame.

Yeah, I went back and skimmed through and they could even absorb the black flame into their bodies for a round and use it to do stuff.

That's cool. 

And I think I recall some of the peoples of the Broken Lands using some fungal spores as weapons. Those were the nations of the "demihumans" aka "goblinoids," so Goblins, Orcs, Hobgoblins, Gnolls, Ogres, Trolls, Bugbears, and Kobolds. (Back in 1e those were all "goblinoids," by 2e, some were and some were not, however most of them, the ones that weren't giants, those were "demihumans." As opposed to "humanoids" which were Elves, Dwarves, Halflings, and Gnomes.)

The more you talk about Mystara, the more I want to get a 5e book for it. I probably wouldn't play in it, but would definitely take inspiration for my world. 

If you look online you can probably find the GAZ series (GAZ00 - GAZ14 published by TSR). They are so old I think they might qualify as open source by now, so finding free PDFs of them might be legal. Anyway, those are the core, the meat and potatoes of Mystara. You know how Mercer's Gazetteer was so well done for Wildmount? Heavily inspired by those. But each of those was basically a mini campaign setting. There were Roman analogues, Norse, Arabian, N American, France, etc. It was vast. If you want my personal recommendations, GAZ01 was the weakest, it was done by someone other than the world's creator and he hated it and handled all of the others personally. GAZ10, The Orcs of Thar was a bit tongue in cheek, so also not necessarily the best orepresentation. My personal favorite is 03, Glantri. But skim them all and see which one grabs you the most and start there. Those are the core of the setting. From there... let's put it this way, I actively collect all publications I can for Mystara, and I don't have all of it, there is so much. 

Nice. I'll see if I can find those. 

Okay, a bit back on topic. Here are some race-specific weapons I have in my homebrew world for the goblinoid society:

• Hobgoblins - Trakaaln (Blade-Staff). It's a metal quarterstaff with a retractable blade at the top. This allows it to function like a ylkwa or quarterstaff, depending on whether they want to bludgeon or pierce, but it counts as a martial weapon. 
• Goblins - Agarthaan (Arm-Blade). A blade strapped to the wrist and hand, similar to a Katar. It's a 1d4 simple, light, piercing weapon that counts as being worn, and is finesse. (You can't use a shield with it, for obvious reasons.) It takes an action and both hands to strap on, and goblins can take a feat to increase its damage dice to 1d6, increase Dex by 1, and strap the weapon on as a bonus action. 
• Bugbears - Techtal (Saw-Shield). A flat, metal shield that is strapped to your arm, with its edge being serrated like a saw. Using this weapon requires proficiency with both martial weapons and shields, and each shield takes a hand. You can use two at once and dual wield them, but this requires the Dual Wielder feat, and you don't gain the AC boost of the second shield. It deals 2d4 slashing damage on a hit and is heavy. 

The men of Íssmadŕ in my world use barbed spears or tridents that are eligible for PAM, because it's my world.

I have a special ray gun-thing built into a homebrew version of a Warforged with more plants and magic.  It deals some weird damage.
