I've recently gotten a BIBB and am wondering how it will fit in a large Spec-ops sheath. Also, does anyone know whether or not the outer storage pouch can be removed from the Spec-ops sheaths? I like the overall design but would prefer a more streamlined package. I'd consider going custom but I haven't come across any sheath maker who could make a BIBB sheath without me sending them my knife. Thanks in advance.
