Carrying a custom knife built through Architect Knives in a Kydex sheath is a fantastic way to protect it. You should also use a sheath to its full potential by outfitting it with a backer. Whether you choose a Kydex knife sheath attachment with or without a firesteel ferro rod holder, you can find backers with all the hardware you need to run through numerous attachment scenarios. Our backers also come with rubber washers that go between them and sheaths to provide ample protection from wear and tear.
Our family-owned business embraces the customizability of knives and carries a vast selection of top-notch knife accessories. From blades and handles to sheaths and sheath backers, you can find all the high-quality, US-made products you need to build the best knife possible. We also offer our customers free USA shipping and a 100% satisfaction guarantee, ensuring they enjoy personalized service while building knives from scratch.

These leather backers are Kydex knife sheath attachments that upgrade the aesthetics of your sheath and can also improve comfort while carrying, especially if you want to carry your knife on your belt.
You can scratch knives with a Kydex sheath, especially if you are not being careful or if the blade is extremely shiny. However, it isn’t the Kydex itself that does the damage. Instead, dirt, sand, and other debris can get stuck in the sheath and scratch the blade. The scratches should be more along the lines of typical wear and tear, not deep scratches or anything that would render your knife useless.
Kydex is popular because of how lightweight and durable the thermoplastic material makes them. It’s also popular because of all the possibilities it presents when it comes to customizing a sheath or adding a Kydex knife sheath attachment. Additionally, people appreciate how easy Kydex is to clean and maintain.
