I bought some lifeboat matches that came in a plastic tube container. I put some of these in my survival kits minus the tube. My problem is I cant find a material that will strike these that I can add to my kit. The striker on top of the tube works great but I can't find a material that is similar. I have tried different grits of sandpaper but they either eat up the match or do nothing at all. Any help woun be appreciated.
