I have some black linen micarta which turns a rustic grey/brown colour when bead blasted ~ like on many combat knives these days.
Micarta is pretty darn tough, but I doubt as robust as the glass epoxy (alloy?) of the original 7's handle slabs. The micarta will give it a 'more grip' feel when blasted and it looks great.
Yes, I too have thought of getting anothet to play with. I was going to try blasting it to see if the plating would come of and then if it did not work, buff the crap out of it on my buffer. Nothing like the smell of burnt coating in the morning...
...But either way, because of the high carbon content on these excellent blades, we would really have to fight the rust away me thinks. But then again, I sorta like the looks of the tarnished carbon blades of old!
Have struck a small problem with the screws so going back to the drawing board....Rev 2 I think they say..
