I'm really sorry but I was so tired and struggled with the locks, which were sticking badly on all 4 pieces I saw, that I didn't even pay much attention to materials or construction details. I believe the liners were either anodized aluminum or titanium and it seemed that the scales were 2-pieces of black polished G-10 or maybe micarta.....that's 2 scales per side, I think. They were light enough, however it required two hands to release the linerlocks on all 4. I do remember that 3 0f the knives had black coated blades an one appeared bead-blasted with the chisel grinds very prominent due to the visible grind marks....these bright heavy grind marks cheapened the overall appearance of that knife in particular, IMHO.
I'm truly sorry to be of so little concrete help with my report. My meds were accidently left at home so I was trying to force a good mood by that time of day.......I think that was part of the problem; that and the sticky lock issue.
