I want to expedite my progression to the agricultural revolution so gonna pull the trigger on the:

• saw: animal pens, plow, later shelter

• tarp: early shelter, water purifier top + inner container, waterproofing

• pot: boil saltwater, cooking food (avoids disease, improves digestion)

• knife: hunting, defense, incorporate into larger traps

Notes: fire can be made with dry wood, rope can be made from twisting local fibers, hiking boits will last maximum a few years (not a long-term solution), iPod's battery lasts a few days, first-aid kit is a good runner-up especially depending on local flora/fauna, two blades (saw and knife) might sound redundant but it fast-forwards our tools into the metal ages which will help us develop agricukture way faster, fishing can be accomplished with nets made from local fibers and chum from leftover animal carcasses, a flare is practically invisible to commercial aircraft and finite, better to place several massive HELP signs on the beaches, raft and compass: you'll capsize on the waves if the island is far enough to be deserted, suncreen is too finite, mirror: there are more efficient ways to start a fire.
