Recycled Brass: DIY Brass Knuckles


Disclaimer: These are for decorative purposes only.

Ok so we have seen some people “recycle” brass in some clever ways. Jewellery, headphone ear buds, arts and crafts. This is a bit more in depth. Most “recycling” leaves the brass intact. Like the .50 BMG bottle openers. This guy melts them down at home. I do not know anything about home foundries so if anyone dabbles in this please chime in.

Grant Thompson of “The King of Random” melts down .223 brass and pours them into a sand mold to make a set of brass knuckles.


He should have used .22LR brass since no one really reloads those.

Phil Note:
Our readers most likely know but brass knuckles are very much illegal in every state I know of.

    One of the reasons I have guns is so I dont have to get my knuckles all dirtied up punching people.

    • Nicholas C

      Tidiness and sanitary is an attribute. Punching zombies in the face could lead to contamination.

      • TheNotoriousIUD

        Not to mention ruin my manicure.

      • mzungu

        That’s what the buttstock is for. 😀

        • iksnilol

          And ruin my authentic shellac finish?

          No than you, sir.

          • Nicholas C

            Gotta think long term. Resale value. People’s dont want joe shmoe brains on the stock.

            Adds character!

    “Our readers most likely know but brass knuckles are very much illegal in every state I know of.”

    Legal in Montana as with almost all weapons, so long as you have a carry permit. I carry a set of knuckles regularly, along with a handgun or two, a baton and so forth.

    The one real exception is automatic knives/switchblades, which are never legal to carry here but may be purchased/collected with a completely separate permission slip from the sheriff.

    • thedonn007

      Well, now I know who to call if the SHTF and I happen to be in Montana

      • Nicholas C

        Not necessarily SHTF. But when someone owes you money in Montana, we know who to call for “collections”.

    • Ken

      What brass knuckles? Looks like a belt buckle to me.

      • Edeco

        Yes, it’s a common decorative motif, not a weapon. It’s like that painting of a pipe that says “Cesi nest pas une pipe”. It’s a painting of a pipe, not an actual pipe.*

          “The Treachery of Images” – I just read its Wiki entry. Pretty cool – Thanks for bringing that to my attention.

  • Giolli Joker

    That guy is great!

  • tincankilla

    would be interested in seeing him make one of those foam swords into a brass sword….

  • Rock or Something

    He should make brass knuckles that shoot a bullet into your opponent as you punch them.

  • AndyT

    If anyone tries this, be very cautious with the brass fumes that are put off by melting. They are toxic (heavy metal poisoning isn’t just an awesome metal band name).

    Brass melts somewhere between aluminum and copper temperature wise. I made a foundry to melt down my .22 lr brass and turn it into mini markers for disc golf, but gave up on it after some research as to the toxic fumes.

    I went with melting copper instead.

    • Edeco

      Brass shakes, bleh. My second least favorite kind of shakes.

      • iksnilol

        Tried brass shakes once… my blender caught on fire :/

        • Edeco

          Probably need a Blend-Tec to pull it off.

  • Don Ward

    Yeah. Metal shop class was pretty fun.

  • Xeno Da Morph

    Yea, I cast this bad boy in they back yard……… Always save your brass kids!!!

    • mosinman

      Brass is such a beautiful metal imo

    • M.M.D.C.

      Beautiful. Is that a palmetto tree on the barrel?

    • Mike Lashewitz

      You missed a spot. I hate polishing brass – NAVY

  • Edeco

    Commendable. Skull sprue at 3:40 lol. Interesting that the styrofoam just burns out.

  • iksnilol

    I wonder if you can somewhat reshape brass if heated to 400-500 celsius. (my heat gun goes that far).

    I sorta want to make some “trophy” or reminder out of some 30-40 .22 LR cases (the first time my girlfriend shot, and she shot very well. So kinda wanted to make something commemorative).

    • Phil Hsueh

      If you’re talking about brass from spent cartridges, you don’t need a heat gun to somewhat reshape it, you just need a decent hammer or mallet and something to hit it on that won’t break. Alternately, you could probably reshape it in a purpose built forge(?) like they use to stamp coins and medallions with at the Ren fair.

      • iksnilol

        That I’ve done, but I think I might need that heat gun anyways. At the very least to fuse the pieces together.

        • Phil Hsueh

          I don’t think that brass is soft enough to weld using a heat gun., What you want is a small torch, something small and self contained would work fine, then you’d need some solder and that would allow you to fuse brass together. It’s not as good as actually welding them together but it’s good enough for display and a lot cheaper and easier to use than a full blown welding torch.

          • iksnilol

            I will have to look into that.

            Just don’t know what to make. I got about 30 .22 cases. What sentimental stuff could I make out of it?

    • BrandonAKsALot

      I’m not sure what temperature brass could be further welded, but it’s usually a process that takes practice. If you have a chunk of brass, it can be hammered into shape pretty easily, but brass work hardens. You’d need to heat it to the point it glows occasionally to anneal it and keep it from getting too brittle.

      It’s not too difficult to build a foundry or forge really. I have all the stuff to do it, but I haven’t gotten around to it for some reason.

      • iksnilol

        I know that one.

        I don’t have the space. That’s one of the pitfalls of not having your own place.

  • Kjk

    It’s kinda dumb brass knuckles are illegal and guns are not. (Neither should be illegal btw)

    • gusto

      I can kinda get it
      I am all for CC and all that. and the right to selfdefense

      but brassknuckles would make every “regular” pub-brawl into a potential life and death fight, too many bros would carry them all the time. I mean street fighting shouldn’t be condoned but if two drunk fools wants to get it on we don’t have to make it more dangerous

      • Kjk

        I see that point too But I thought this was supposed to be a free America. If you commit a crime with them it should be assault with a deadly weapon which would be worse than a fighting charge. They could be a good defensive weapon where a firearm would be uncalled for such as getting sucker punched.

  • DW

    I still dont understand why some jurisdictions outlaw brass knuckles while daggers are ok. Dont take me wrong, they all should be legal, but still, logic is stronk.

  • Jonathan Wright

    I see your recycled brass knuckles, and raise you a recycled dirtbike sprocket kuckles.

  • Sgt. Stedenko

    As soon as I saw this picture, I knew Nicholas C was behind this.

    You just need to affix a holo sight and a laser pointer to the brass knuckles for him to bite.

  • Mike Lashewitz

    Drill and tap out a hole near the center side of the finger end and place a “belt pin” into it. Voila you have a legal for sale and wear belt buckle.

  • Markbo

    Some day I’ll learn. I know I will. If Nicholas C. writes it I am not interested. I just dont know how to tell before opening the link.

  • pismopal

    Yes…just explain that they are for decorative purposes….just like the shiny handcuffs.

    • Edeco

      The handcuffs could be a marital aid…

      • pismopal

        They are going on the person with decorative brass knuckles

  • Mi

    Brass knuckles are not illegal in every state. In my state they are legal but illegal to use in a crime. In other words you can still use them for self defense.
