>>2823226 (OP)>flintsLiterally any standard flint you can get. I'm using Zippo flints in mine.
>best lighters for outdoorsThe modern Imcos. Junior or Triplex, doesn't matter. They're pretty much the same as a zippo, except they seal properly and won't dry out overnight.
>>2823231>my zippo always fires up first strike, my IMCO take like 3-4Sounds like a user error. Both mine (modern Japanese production Triplex) and my father's (inherited 1920s production Junior) reliably start on the first strike. The only times I ever had trouble were with using "wrong" fluids (30 year old lighter fluid I found in the workshop, where all the volatile compounds were long gone, and ethanol when i ran out of fluid once). But even then, it'd still light on the first strike, the flame just would take a while to gro to full size.
>bicBics suck. If you go down the "cheap gas lighter" path, get those electric ignition chink lighters. On the bics, the valve takes way to little force to actuate, and if anything pushes against it in your pocket or pack, they'll be out of fuel even faster than a zippo.
>>2823252>this slider that says IMCONote that not all Imcos have markings there, though. Some of the old austrian ones certainly do not, and iirc, some of the early japanese models (the ones with shell inlay in the grip, I think) also don't. Some people falsely assume that those are copies.
