This sheath has light retention and was originally designed as a cover for the live blade when training. This sheath does not come with an attachment clip but you can put one on. Mostly this sheath is used for putting velcro on and installing in your kangaroo pocket on a PC or sandwiching the sheath between a duty belt. If you want a full retention sheath buy the MDV Retention sheath not this one. this is the same sheath that comes with the Aluminum MDVs.
