Just had a thought today as I was looking at a Clipper lighter, that it they may serve as cheap landing gear for people doing aircraft customs. I hope you know the ones I mean. Inside the lighter itself there is a slender removeable shaft which holds a changeable flint. The flint provides the friction and spark, so removing that leaves it to spin very freely. The removal is very simple, a quick twist will do it and it all pops out. I imagine with some cutting and sanding it would easily fit in a peghole. Just a thought for folks, I've not tried it yet myself. There are also smaller mini Clippers for smaller sets and they cost about a dollar/euro.
