Also, why tuck your hose behind something that you are possibly going to remove and use? If you don't have a can light and don't want to buy that halcyone thing, you can just cut a piece of PVC pipe to length to make a fake canister.
You don't "remove and use it", you pull the knife out of the little sheath. See pics below. Why add a piece of faux gear when you can use a piece of real gear to accomplish the task?
But I don't see the point of those blunt DIR knives if you have shears.
Back in the day, way way before Bill was Hogarth or DIR was even a gleam in the eye... We were dealing with a lot of home-made gear with little stainless screws. lotta times we needed a screwdriver when we were a long way from the truck. Hence the dollar store steak knife with the sharp point cut off. Since it was a knife it also served nicely as a cutting tool.

The pic below is of a scabbard I made in about 1975 (yellow) and the dollar store steak knife. The black one is a relatively new one included in the package when I bought a DSS plate and wing. The webbing is really stiff and serves nicely to keep a 7-footer tamed.
