The Warriors Way, TX / Head Hunter Blades Rat blade has one of the most comfortable to wear sheaths I have ever worn for a blade.
Small eyelets.
The clip is very good as well, catches on most belts of most sizes and difficult to rip off a belt during use.
Another close up of the clip and sheath, you can see that this is a pretty good quality product as I've used it extensively and it looks excellent.
The entire design is centered around implementation of the Rat blade. The sheath allows for ambidextrous use and mounting of the Rat.
The perfect amount of blade is exposed for just the right master grip during initial draw.
