I have SAS Survival compasses from Triple Aught Design mounted in the caps of my CRK's, via some clear Marine grade silicone.IN the handles I have dry unlubricated condoms to hold my supplies.I carry water proof matches,fishin line,hooks,sinkers,iodine tablets, sewing needles,an item or two more.The larger One pieces you can fit more stuff in the handles,but I have enough of the basics in my small one piece.I also have a firesteel and DMT diamond Mini-Sharp's mounted on each sheath.Well,actually have a LDC pouch zip tied on my Concealex sheath from On/scene tactical that I bought from Murray at Proedge.The On/scene concealex sheath for my Mountaineer II, I have concealex holders/adapters for my Swedish firesteel and DMT Mini-sharp as part of the sheath that On/Scene Tactical made for it.That's about all I have in or out of the handles.
