Here at Brasswerx we're all about brass and nothing screams brass more than spent ammunition.

** You have to let me know if you have a waveless knife. A small modification is needed for these to fit on a non-waved blade.

You can go with a 9mm, .40, .223, or any other small caliber shell casing to maintain the size of the factory disc or really make your knife stand out with a large caliber like a .45 ACP or a .308 rifle round.

Each disc is sized by hand to the hundredth of a millimeter and is guaranteed to fit perfectly. Each disc comes with a polished shine and will naturally patina over time as you use it. For some knives, I also include an extra screw in case you lose or strip your factory one.

If you want a specific manufacturer or caliber please specify in your order notes. Otherwise, I will default to 9mm for small caliber and .45 ACP for large.

I make these as orders come in and it can take up to 3 days to keep up with demand.

For CONUS orders shipping is on me and all packages are sent First Class with tracking.

For International shipping, the way this site works is different. They don't let me chose based on your location, I can only list a flat fee. Since some countries are as high as $15 for shipping, I have international shipping listed for $15 and I will refund the difference back to you. If shipping is only $3 for you, I'll send you a refund for $12.

I guarantee 100% satisfaction so if you get yours and you find that you want to return it for whatever reason then send it back for a full 100% refund.
