Protect Your Blade
No matter how durable the knife you design with Architect Knives’ Knife Builders tool is, you should still aim to provide it with plenty of protection by investing in a sheath. This AK 5.5 Knife Sheath, constructed from an extremely durable and long-lasting Kydex material, will enable you to do just that.
This high-quality, CNC-machined black knife sheath for the Architect® Knives AK 5.5 features an ambidextrous, compact design and an innovative Slide Lock securing system. It can also be utilized in high-ride or low-ride positions, giving you the freedom to choose from either vertical or horizontal carry and making it easily accessible from any angle.
A Black Knife Sheath That Is Compatible With Many Accessories
The best part about this AK 5.5 Knife Sheath is that it’s compatible with a wide range of attachment carry accessories, allowing you to enjoy more versatility from the second you stick your custom-built knife inside it. It pairs nicely with many Architect Knives accessories, including the following options that are sold separately:
- #1 Leather Drop Loop Backer (with or without firesteel loop)

Very happy with this knife as a companion to my two Field Buddy 6.5 knives in 1095. The shorter and thinner blade makes for an easier carry, with minimal loss of function. Great warranty service from TKC dealing with packaging and shipping issue, fully resolved. — Originally posted at TheKnifeConnection

Just what you want in kydex- good snap and clean fit. Not sure I’ll use the slide lock much, but not a bad option… — Originally posted at TheKnifeConnection

Loving both of my architect knives. I used to be a big fan of ESEE and Becker Knives, but with AK offering better steels at competitive prices, and now multiple sizes, id say AK has them both beat.
