The Izula is probably going to end up being the top seller for RC. We already have a huge overseas interest in its release and we field emails and calls daily from all over the world wondering when it will be available.
The sheath that we (Shon, Mike and I) designed is probably the best small knife sheath I've seen to date. You can attach it with a neck lanyard, MOLLE lock, Tek-lok, paracord, lashing, etc. The MOLLE lock has about 45 degrees of adjustment so you can carry in between horizontal and vertical. The sheath is also symmetrical for for a reason: we're designing a quick-disconnect base plate option that will allow the user to click the sheath into a a base that remains attached to your gear. Being that it is symmetrical, it is fully ambidextrous for all the carry systems, including the base plate option that we won't be releasing until Blade Show. We also have another option we're working on that's cool as hell and never been done. Stay tuned, we're just getting started!
