We use a couple for lighting candles. I tried using one to light some magnesium shavings and it was kind of a dud. Even a strike-anywhere match took a long time on those, but a spark rod got it going after a good direct hit.
Put one in my pocket not long ago as a backup to the piezo on my flame gun. Dang safety got switched off in my pocket and when I pulled it out I found out what that little bugger feels like on your finger. No burn, just a good pinch.
