If you use a long hose configuration...

If you don’t use a canister light, not sure you need a 7’ hose to be honest.

this comment is stupid. I see many cave divers that use handheld primary lights instead of a canister light. you don't need a canister light to do penetration.

Valid point. I'm not a cave diver. I had not realized how many have moved away from canister lights. I should have said that if you aren't diving in an overhead that may require single file exit, a 7' isn't really necessary.

Burn times on held held lights are pretty good. Right tool for the job and all that. However, it's not just useful for overheads with a single file exit. If you want the oog diver on your left you'll be grateful for the extra length too.

That length can be nice to do a distance swim (like traversing a shipping channel), or just an easy ascent...

A few years back, we were doing a very benign drift dive. Early in, we had an issue with one of the rigs. As it was a timed dive with restrictive exit point, we just did the dive (about 30 minutes) with diver #2 on the long hose...

was fun...

When I started diving with a long hose I had a knife on my waist strap that the long hose was tucked under on the way to my neck. I got use to that method and both of my plates had a knife in that position.

I realize this is probably not an issue, but it feels wrong to route the long hose, the primary breathing supply and donating reg under a cutting device that could sever the hose. The sheath should keep the hose safe, and if it didn't it would also be a puncture risk for the drysuit which I don't hear about causing many problems, but it still feels wrong to me. I also wonder if there is a risk when getting the knife out of the sheath that it may come in contact with the hose in a cutting motion...

I tested that theory: not even a mark on the hose.

Rubber LP hoses and even the braided LP hoses are not all that easy to cut. It takes some concerted effort even with a razor knife. And to (immediately) compromise the strength of the hose the cut would need to go through the outer rubber or braided covering and into the nylon reinforced section or the poly sleeve if braided.

However, I thought the cutting instrument was to be a blunted and dulled butter knife and that the knife was to be located on the left waist strap just forward of the hip D-ring and thus retained from falling off (when getting in and out of the harness) by the buckle. Seems to be an awkward place to tuck a long hose .
