Normally I have liked Iron Wire for a touch hole pick, as it is rather soft and won't harm the barrel.
However, there was one time the sharpened Spring Steel Wire pick for my Brown Bess came in VERY handy.
A good friend in the unit came to me minutes before a reenactment was about to begin and asked if I had my Worm on me as he had a patch stuck in his barrel that would interfere with blank firing. Sure enough, one of the few times I did not have a worm with me (and never again after this experience) was when he needed it. He knew enough to keep the points on his Worm SHARP to grab a patch in the bore, but his Worm was around .69 caliber and wouldn't catch the patch in his .75 caliber Brown Bess. Oh the embarrassment! Two Retired Senior Staff NCO Marines who were really persnickety about care or our Muskets and neither of us had a Worm that would work. :shocked2: :redface:
I had him put the Worm on his rammer and tried holding the Musket so he could "worry/work" the Worm around better in the bore, but we still couldn't get the Worm to stick on the patch. Then it dawned on me to use my Vent Pick through the touch hole to spear the patch and hold it from turning, so his Worm would catch on it inside the bore. Took only two tries and we got the patch out by the "spear and catch" technique.
Though that was the only time that happened to me in over 35 years of using flintlocks at the time, I filed this experience away in case it ever happened to me or others again.
