Just a few sheath questions:

1.) Will the small Spec Ops Sheath fit the DMDC?
2.) Opinion: Just wondering, seeing as I'm new to carrying fixed blades, is there any advantage to Kydex over what appears to be a standard sheath like the Spec Ops?

Just looking for a little input. I want to purchase a sheath and some of the makers in the Yard seem to make good stuff. I just don't know if one is better or more functional...etc. Sorry if these are noob questions, but I am a noob to the fixed blade.
