I needed a kydex sheath for my Candiru so I contacted my buddy at Dark Star Gear. I have a good number of their pistol holsters and have always been pleased with the fit, finish, & function. The maker is always eager to try new things so when I contacted him about making me a sheath he jumped on board. Coincidentally, he had already been working on something that fit my needs.
The sheath is a simple taco style with a single screw that serves to both adjust tension & to attach a single soft loop w/ a Pull The Dot snap. The PTD snap allows for quick on/off capability. DSG also punches extra holes in the soft loop so you can adjust it to accommodate different belt widths. I have been wearing mine on a 1.5" Wilderness Tactical belt and once I changed to a different hold it doesn't move at all. It stays put and is rock solid. Out of the box the tension wasn't as tight as I prefer but after a couple of turns of the screw the sheath holds the knife very securely.
This sheath has absolutely made the Candiru a part of my EDC setup. I have worn one of these for the past couple of days on a dinner & movie date night (under an untucked button down along with a G19 worn OWB and an extra mag pouch) and running errands all day today (under an untucked t-shirt along with a G19 worn IWB). The sheath holds everything close to the belt but allows enough room to get a solid grip for drawing the blade.
My neighbor saw me outside taking these pics and now wants one. He isn't even a knife guy.
Here are some pics of the Candiru sheath.

Here is the same style sheath for the Izula I/II.
Here are a couple of sheaths he made me for neck carry.
