Pete, you saying that puts me in mind of crab legs.

Hacksaw, thats a nice striker+steel+magnesium rig in the background of your 3rd picture. Where did you get it??

I've been looking for another good one for my kit.

It's a Coghlan's Magnesium bar. I modified it slightly by adding the striker from a Light My Fire Firesteel and joining them with some paracord.

I've since upgraded again by switching the Light My Fire striker with a fine toothed jigsaw blade...WAY more sparks and I can scrape (saw?) off a pile of shavings in way less time and with way less effort.
