Trangia burner.
I'd say the whole setup.
I'm surprised that the P38 can opener hasn't made the list yet....It has now!
Canned food? Scott used it and apparently when some was opened recently it was still edible. Freeze dry etc. has its uses but I keep a can or two of stew in the van and sometimes a can of bully beef in the pack. There have been times when heating has been impossible and cold bully beef has seemed like a gourmet feast- yes, I've really been that desperate!
Optimus paraffin stove. Still used in the Poles (45?) because it is simple, bulletproof, effective.
Can I take cost into account? I'll take that as a yes!
For around £35, the MoD knife (tree beater)! Back off knife snobs! Lol
For me and my use it's perfect, 500g lighter then even a hawk, good chopper/splitter. Possible to carve, I made a bow drill set just using mine. Easy to get shaving sharp. Though I should say I've put a scandi grind on mine, and a (I think it's called) drop point, so I can get the tip in for carving. If I was stranded and could only pick one knife, I know it wouldn't let me down.
Cheers

I agree that the MOD knife is a great knife but I think it's in contrast to the concept posed in original post of kit that's "never been bettered." The first knives were flint, then "bettered" by metal, then better metals and designs. The end result was the MoD knife. That means it isn't an original in itself, but rather it IS the BETTERED version of the original.
