No idea on the specific requirements of the team; however, if you are required to carry a knife on a lower extremity, it is what it is. With that said, wear the knife on the inside of the leg to reduce the possibility of catching on anything. Also, if not wearing spring straps, invert your fins straps so they run from the outside in, this also helps reduce the chance of entanglement.
To cover the requirement, I would glue a small, neoprene pouch on the lower leg section that was just big enough to secure your knife. As noted, the lower leg is not the best option for carrying a cutting device so it might be more of a place it and forget it type of option. Keep your primary located just off-center of your center strap on the right side of the buckle (BP/W) and you should have easy access with one or both hands should you have an issue. I always carry shears in a pocket just in case that I can reach with either hand.
Cutting devices attached to a BC or tied into hoses may present an issue when attempting to put the cutting device away in an area you can’t easily see. I have seen a few cut hoses and cut BC’s over the years from folks trying to jam a cutting tool back in a sheath. Anyway, keep it minimal on the lower leg with the notion that it is only a last resort. Working in a group is not as critical but if you are doing solo work, plan accordingly.
