Update - I added a touchmark which is pictured in the second photo which supersedes the other images where it's not visible (but should be).
This knife was forged from a billet of 15N20 and 1080 that was twisted and split in half to show the inner pattern on one side and the twist on the other.
The edge is roughly 5 1/4" long, the overall length is approximately 9 5/8", the blade is roughly 1/4" thick at the spine and weighs approximately 6.85 oz (8.75 oz including sheath). The handle fullered to reduce weight, the handle is partly wire brushed and left as forged while the blade was ground, leaving more of a raw finish on the handle.
This knife was normalized 3 times, oil quenched and tempered twice, two hours at 425F and two hours at 400F. The knife will ship with the hand-stitched bridle leather sheath pictured.
I forged the damascus billet from scratch with a hydraulic press, and then hand-hammered the billet into a knife, followed by grinding, filing, polishing, etching and re-polishing. I do not re-use damascus stock bought from someone else.
Note 15N20 and 1080 are not stainless steels, so periodic coating with something like mineral oil or carnauba wax is standard maintenance - frequency depends on the 'climate'.
This knife is sized to my hand and I generally wear Mens Medium sized gloves.
