Definitely going to try this one. I have two Zippos--a 2015 I bought new at Walmart, didn't get the fuel for (didn't know a local cutlery store sold it), and disassembled (and for some reason, removed the flint, wadding, and wick from) and recently re-discovered in a box of junk. A couple months ago, after sourcing the parts (and fuel) from the cutlery store, I bought a 2005 secondhand on the way home at an antique store. I got the 2005 working without a hassle (flint and refill). But, I figure for the headaches the 2005 will be, I might as well put the bit insert in it and try it.
