That's a plug piped.
Slice a flake from it across the grain/layers. Thickness is entirely up to you of course!
From there prepare the flake as you prefer, rubbed out or further cut into cubes. When I go for the cube cut I shoot for pieces somewhere in the area of 1/8".
This one smokes best for me after it's dried a good bit.
Not a bad blend all in all but the plug is not as densely compressed as say, Petersons 3P's so it makes it hard, for me at any rate, to produce an actual flake from the thing.
