An old friend and I are pretty tight with a nickel, but decided to go halves on a French amber.
We flipped a coin we had borrowed. Jack never returned it.
I got to try the flint first. I used it for about a hundred rounds, then gave it to Jack. He claimed it wasn't sharp as it used to be, and was awful short for his trade gun.
So, we had mixed reviews when all was said and done. I had better results than he did for some reason.
I use black flints, and am perfectly happy with them.
