I just received this folder this week and have had a heck of a time photographing it. I get the photos on the computer and I see dust or other debris and getting the hamon to show was hard too.
It is a commissioned piece by John Doyle in Michigan.
Specs are as follows:

7 1/4" open, 3 1/4" blade, 4 1/4" closed
W2 steel blade with hamon, .115" thick at the plunge line, full distal taper, Rounded spine
Rounded, filed thumb grip
.060" titanium jeweled liners
Desert Ironwood scales
Titanium pivot and handle screws
Bronze backspacer with lanyard pin
Bronze thumb stud

I am really happy with the way it turned out
