Hi guys,
I'm the owner of 
Going Gear and also the guy selling a bunch of firesteel blanks on ebay.  I was poking through my referral logs, and saw this thread.  I thought I'd say hi and answer any questions that you might have about my or anyone else's firesteels.  I have owned and used most of the ones out there, so hopefully I'll be able to share some knowledge I've gained.
