Hello. I'm trying to decide what to put in the pouch on the sheath, whether it's a Becker BK16, BK7 or BK9. I'm probably not going to put another smaller knife in it. The main debate in my mind comes down to whether to carry knife specific stuff, like a sharpening stone or rod and maybe some duct tape or band-aids in case I accidentally cut myself; or, to carry other survival items like a lighter, ferro rod, tinder, fresnel lens, bank line or paracord, canvas needle, or maybe a bullet-style space pen, etc. If you have a knife sheath with a pouch. please let me know what you've decided to put in it. Also, please let me know if you actually carry it and use it on a regular basis, or if it's usually in an emergency pack or something. Thanks.
