* a heat gun on LOW or a hot hair dryer on high
* some heat resistant foam to 'mold' the Kydex to the object [works equally well for fixed blade knives]

* Rivets or grommets and their setting devices
* I used holster clips but you could just as easily bend a piece and make it into a belt loop [think 'cowboy' holster]..
