I have the black and tangerine. They are nice, but the scales are slipery and the edges are a little sharp.
He should have put the Tangerine on Ramblers at a minimum, waste of a custom scale on the Classic I think. I have not tried removing the scales yet to see if they can be put on different knives but that is my plan. I think I'm going to try to drill a few insets for grip as well. The scales are thick enough as well that scale-tools could be accomodated if the equipment to cut the slots was available.
Nice Idea, but I'm looking forward to them evolving.
