I have a couple of Scout 7NH and a Explorer 10NH made by
Mag Flint Firestarter They are small and fit into a small kit well.
I also have a couple of small
Mag Fire which are very good little starters.
Another I have in my Favorites is
WSI but I havent used them.
I have a fire piston from
Primal Connection which just arrived, and
Wilderness Solutions also sell them.
You seem to have a lot of others already covered.
