I tried a different tack and phoned Tufnol UK to enquire whether the custom material mentioned on their site extended to colors, as per the Ultrex material. Very nice man in their sales team said they do only natural colors, no reds, blues or greens. Bummer

After making a bit of an ass of myself being so adamant, I didn’t want to be wrong and look more of an ass….but it would have been cool if they had made colored material!
No hard feelings???
Easy mistake to make based on the GFS page if you hadn’t encountered the brand before.
Tufnol cotton/phenolic is good….if you like khaki. While it starts as an almost yellow khaki, it darkens noticeable with UV. The Carp type, which has a fine weave cloth and is kinda £££, darkens to quite a nice warm brown, eventually.
It will be interesting how those brilliant colors on your knives hold up with time.
