I prefer the Firesteel.com 'steels to the LMF, personally. FWIW I can't get my head around why anyone is bothered by the fact that they sell an enormous 'steel! So what if it's bigger than you'd use- it would still be very useful! I'd love to have that steel. The largest one I have is the "Bunker", and you'd probably find that too large, too. For the record, though, my favorite model is the GobSpark Armageddon.

I completely agree though that if you start a lot of fires and are technically proficient at firecraft you may as well use a lighter. It's hard to beat a BIC in conditions favorable towards its use. However I do think it's a great idea to use other methods frequently enough to retain the ability to do so. The time that your lighter fails will probably be the time that you need it most. In that instance it's good to have other options.

Few ways of making fire are more reliable than a firesteel. They work in any weather, at any elevation and at any temperature. They're completely unaffected by being doused with water. They do of course require tinder, same as every other method. PJ cotton is great. ESBIT is outstanding, too; it can serve dual roles as tinder and fuel.
