Hi Craig,<br>That is interesting. I just ruined a few of my lifeboat matches trying to ignite them on the nail files of my Leatherman PST & Micra. After destroying a few of them, I tried another on the stiker that comes on the lid of the plastic bottle they come in, and it worked great. I'm using NATO 9920-99-966-9432 matches, which, I'm pretty sure, I got from B.C.B. Int'l. Are you using the same ones? If so, any idea what I'm doing wrong?<br><br>
