No sir that sheath was made by yellow hawk custom kydex. He has a website. https://www.yellowhawkcustomkydex.com/
No problem. His sheaths are pricey and take about 3 months to get because he's so busy but they are good.
Wildbill247365 on this forum. He did the HEST/Izula II SHEATH as well. Excellent and well built stuff.
I guess all ESEE knives were media blasted before it was powder coated. After removing the coat, I did not sandpaper it but applied Turco Rust Converter. Its a rust inhibitor and that produced a grey stonewashed look.
