I agree, Treeseeker.

I should have clarified my story above. The first BIC was one of those electric ones, and was carried in my pocket. It worked later so wasn't out of fuel. The second was a mini with the child proof device removed, kept in my fire kit. It wasn't out of fuel either. It may have been the effects of cold on the lighters or on my hands, or the problem may have been my adrenaline.

I have since ditched the electric and up-sized most of my backup BICs to full size, but still carry at least two methods when I'm in the woods.
