I've been watching YouTube videos on making Damascus and came across this one. I thought you might like seeing a contemporary video of someone producing a knife which comes close to the Crolle patterns we see on our Parkers.
A lot of the technics used here are similar to Dr. Drew's video of the old boys in Belgium making barrels.
I found it interesting & thought others here might also.
