The question is, should a newly made "Camper" be:
a) An homage/replica of a tool that was useful for camping in the 1930s or
b) A tool that would be useful for camping in the 20-teens?
Just to cut to the chase, I vote "none of the above" everytime I hoist a backpack. I typically carry a locking folder with a 3"-4" blade backed up with a Leatherman PS4 Squirt in the 1st Aid Kit.
I've not needed to deal with leather on a hiking trip ever. I keep an Army style can opener in the cook kit but honestly haven't needed it in very long time except for an occasional car camping trip and then, my wife needs it and expects to find it with the utensils and not in my pocket.
Modern camping means repairing and field service of modern materials. A small set of pliers is useful for driving a heavy darning needle through multiple layers of nylon and webbing. Scissors are useful for doing repair sewing and bandage work. Phillips headed drivers need to be added to the mix along with a smaller flat head driver.
My choice for a modern camper would be as a useful EDC option. I would choose the following blades:
1) Spear point (in the style of the old Ulsters)
2) Folding scissors (in the style of the PS4 or Wegners)
3) cap lifter & flat head driver combo blade
4) nail/metal file & 2-pronged phillips head driver combo blade (in the style of the Leatherman Micra).
Last comment... The Leatherman Micra is in my LFP most days with my EDC knife of choice in my RFP. The Micra is amazing for it's size, particularly the scissors which are much close to shop shears - Very strong. As much as I emotionally love old Campers (and I do), a modernized version would have to really wow me to displace the combination of a traditional locker and a Micra.
