Yes they definitely both do. Im actually in the process of trying to put in another knife order with Mr. Wilson. No response back yet, fingers crossed he is still taking orders.im sure once that production south fork hits the shelves it will be impossible to get an order in. Elmax fixed with a slighlty thicker blade then the south fork around 3.5 ".edge retention similar to zdp and xhp. Toughness of elmax is awesome from what I hear.it will be extremly hard to rust. Almost sounds like its the be all end all steel for me ......for now anyway
