Time to Play With Kydex


This knife is getting a new sheath.

By now most of us know what Kydex is.  It has great attributes for the barer of the knife to be sure but it also allows knife makers to spend more time making knives and less time stitching leather.  However, I’ve found that there are some learning curves to figure out.  I won’t go into all the details, but I will show you some important things to keep in mind.

Depending on the thickness of your Kydex, the temperature will vary.  I recommend .06 thickness for a sheath.  Make sure you wear gloves when you handle hot Kydex too.  When it’s hot enough, wrap your knife in the Kydex shiny side in and clamp it down in between the foam.  Let it cool for a good 5-10 min before removing it.  If you mess up, you can just heat it up again and start over.  Yet another great perk to Kydex.


I used the heat gun to flair a thumb ramp. Be careful not to heat up more than just the tiny part you want to flair and only get it warm enough to mold.

Drill the holes and cut the outline.  Next, starting with the heavier grit to the finer grit, sand and finish the edges.  Make sure to clean out any and all debris inside the sheath.  If you skip this step it will scratch your blade up pretty bad; I learned the hard way.  Now you can press in your eyelets and buff the edges of the sheath.

A couple good sources to get your supplies is knifekits.com and usaknifemaker.com.

One last tip – put some painters tape on the knife before you press the Kydex on it.  It will give the blade just enough clearance without a ton of friction.  Check out PhillyEDC.  He runs a successful business working exclusively with Kydex and has a few video tutorials that can be useful.  Stick to the tutorials though, as sometimes he can get a little salty.  I’m really pleased with how this stuff works and how many things can be done with it.

Be safe.  Use wisdom.  God bless.
