What items are in your kit that "no one else" has with them? For me it is tools (axe and saw mostly), repair stuff and sharpening "stone" (DC4). And cordage. Normal people never carry cordage, no idea why.
Titanium spork
Everyone else takes the p155 so I must be the only to actually have one
I doubt I have nothing that others don't use, but one I haven't seen on this list is a quality compact monocular. Even small bins are pretty bulky but my opticorn monocular is smaller than a marker pen and is great for spotting game, birds, finsing routes etc.
