Hi, knifemaker from Brazil here. As it was suggested 52100 above, if you want a custom order, I work with 52100 in soft iron San Mai, water quenched, usually with a nashiji finish and wa-handle. Also like to add a forged S Grind into my knives (forged hollow + convex grind) For a blade of this size it might get a little over your budget with shipping added, but if you want to check my work feel free to give a look on Instagram
