This is one reason I think 'little'of knives with hollow handles or tang compartments to carry kit.
People start tailoring the gear to the premise of fitting, not working. This was a fad on survival sites some years back. I think the guy who announced a spent .22LR shell was his signal whistle epitomy of this trend. I never received a reply to my question 'do you use the shell AFTER you kill a charging grizzley bear with your M6 with the fancy paracord forearm or just use one for making a fire?
People are buying $350, 2 lb, 1/4' thick knives and stuffing them with crackerjack prize kit.
