This is harder than the nose stall but not too much harder. You should know how to nose stall before you do this. (I mean Ollie to nose stall because you can't ride onto a K-Stall). Come up at a fair speed. When you get close enough Ollie. This is just like a nose stall until it comes to landing. In the air twist about 45 degrees. Then put all your weight on your nose. You should land on a crooked nose (grind) stall. To come out you can just twist or learn other ways.
