Welcome to the Yard, adamlau. So you found a Yard Hook already? Congrats. The standard SYKCO 6" Cordura sheath will fit it. It fits a lot of 6" to 7" blade knives. On mine, I notched out the liner for the blade catch so it would seat better. They are available at the Scrap Yard store. Or you can have a custom leather or kydex sheath made for it by leatherface, rainwalker, or some of the other sheath makers here on the forum.
