How is it done today, does anyone out there know? .

Certainly the Solingen people had a machine with little wheels...presumeably small grinders..and hollows were the heavily grooved out blades as seen on Colichemarde blades. Below is how the normal fullers were hammered into a flat blade but this was a different process to Colichemardes. I dont believe these blades were drawn out like wire... but ground out with spinning grindstone wheels..The Forte being left flat for strength though you will see some coli blades with three faces all the way to the guard and no squared off Forte.
Below the black arrow denotes the mallet...for ordinary fuller placement on flat blades.
