This old chestnut again, I'd love to see it come to fruition.
Considering the varieties of WL out there, perhaps a kit of parts so that each member could individualise their knife. A stamp on the blade is all that most makers/collector use to identify their knives, so handle design would be up to the individual (and reduce the amount of work by the eventual maker). Following the blade stamp, a sheath with the BCUK logo would be great too.
Its going to cause an arguement whatever design is chosen as so many folk prefer this grind above that one, and don't like to woody clones as they're too samey! Perhaps a limited edition or very limited choice would be the way to go - though price for the masses becomes an issue...
.. for heavens sake someone stop me ranting on.....
