Pictures of the patch knife or knives when they come in?
Back when I was a Mountain Man, I (and 99.997% of the others) used our straight razor to cut pillow ticking patches when loading our rifle.**
I don't think I ever met a Mountain Man who shaved ... not even when he got all gussied up for the Rendezvous.
**(After putting in the powder charge) Place the pillow ticking over the muzzle.
Place ball on top, using the short arm of the short starter, press the ball into the muzzle.
cut pillow ticking flush with muzzle.
Using the long arm of the short starter, push the now patched ball in as far as possible.
Use ramrod to push patched ball onto the powder charge. (You want to slightly compress the powder charge.)
I had three brass or copper rings inletted on my ramrod.
The upper ring's bottom edge was flush with the muzzle, to show the rifle was not charged/loaded, and that nothing (like a cleaning patch) was stuck in the breech.
The lower ring's bottom edge was flush with the muzzle when the rifle was loaded correctly for hunting. (110 grains Fg under a patched .440" round ball was my "big game hunting load")
The center ring's bottom edge was flush with the muzzle using 70 grains FFg under a .440" round ball, which was my target shooting load.
Rifle was a .45 Calibur CVA percussion "Kentucky" rifle, with 33.5" barrel.
Broom sticks at 100 yards were no challenge to hit.
