MichaelRothenpieler I have no idea. I don’t think I’ll even try them. I’d rather not know. Keep them unused.
If the gas regulation/restriction foam wasn’t blocked already from the factory I’m guessing sitting on a shelf for 20 years under spring tension will have definitely taken care of that.
I have ordered a bunch of different sizes of lighter o-rings and a couple of different types of lighter gas regulation/restriction foam so I could rebuild these if I wanted. But if I never try them I won’t be tempted to pull them apart when they don’t work.
I’ve once again crossed the line into knives I’ll never carry or use.
