I found these items while surfing last week and thought they would be interesting to share.
Someone on BPL mentioned the newer UCO match case and I picked one up– REI has them. They hold 25 of the long storm matches and have a slot inthe side to hold a striker and come with a couple spares. It weighs 1.5oz and is a fat little handful at about 3-1/8" tall and 1.5" diameter. I ran into a smaller and lighter version that holds 15 of the shorter UCO storm matches, weighs 0.54oz and is 2-7/16" tall and 1-1/8" diameter at the widest point. The top edge of the cap is textured to aid opening. It does not have an o-ring seal like the larger version. I think it is a good option for emergency-use only. I want to glue a button compass on the top.
I also found a smaller version of the EXOTAC firesteel. It weighs 0.51oz and is 4-1/16" long, with a firesteel that is about 3/16" diameter. The handle is 2-7/16" long and has a textured grip. The striker stows in the handle and has a 1-5/8" grip. The metal of the stiker is milled so that it has a sharp raised edges on all four corners. I like the gripping surfaces on this firesteel. If you hands are cold and wet and you need to get a fire going, you want all the help you can get. This one will still fit on my survival keychain. I do want to replace the lanyard with something denser.
