Very nicely done. I like the handle material for the blade.
I don't do leather any more but you may try a shoe repair shop. They may be able to make you.
"Damascus" steel as it's known today is just two types of steel forge welded and folded/twisted/etc to make either a random or engineered pattern. The blade is etched, with the two types of steel reacting differently to the etching solution producing contrasting shades.
My favorite damascus maker is Devin Thomas; check out some of the damascus patterns he has created a bit further down this page:
