here are the knives I would bring:
- machete (sharpened up real good) - anywhere from 10-14inches. A good traditional hand forged parang (see valiantco survival golok or parang borneo) will outchop any of those stamped steel sugar cane machetes. however, it'll rust like hell, but heck, the tree limbs aren't going to complain. I would try and "oxidise" it with lime juice first so that it develops a patina before using it for the first time. bring a file or medium-coarse sharpening stone/puck to touch up the edge from time to time. diamond sticks and 4x1 DMT diamond stones will take too much time. Sandpaper works really well (fold a shirt over wooden planks as the base).
- STAINLESS STEEL knives (cos the humidity and moisture will just rust everything away) - cheap ones are best. I used the Spyderco Endura VG10 to great effect my last few trips into the jungle. I think D2 will not survive high humidity, warmth and constant moisture as well as S30V or VG10 or 440C.
- I would also bring a cheap stainless steel kitchen knife (say the Victorinox paring knife / 5 inch chef's knife, plastic handles) for food preparation. This will also be the knife everyone will abuse in camp.
- lastly, an SAK - the scissors, saw, file, tweezers (what a lifesaver) are particularly useful. Also, my SAKs seldom rust in the jungle.
well....that'll be me anyways (I live in the tropics). My very last trip in the jungle tho' - I just carried a cheap forged machete (10 inch), a sharpening stone used by rubber tappers, my SAK and my buck mayo. I realised that S30V on my buck mayo lost its edge very quickly (for that matter any steel) when I used the bottom of the mess tin as a chopping board
oh...bring some cheap stainless steel knives (opinel or SAK) to trade with the locals or as gifts.
