There is no direction to the figure but rather splotches of end grain from the figure rising to the surface and shaved off by the planer exposing the curl. Yes sharp tools are essential and much care in finishing to avoid the fuzzing from the exceptionally irregular grain. What this figure reminds me of is a pot of boiling water, frozen, and then shaved off flat to expose the mountains, valleys and side hills of the bubbles. The mountains and valleys remain light in colour and the side hills soak up stain and oxidation. The grain is quite open in this wood, but is more or less parallel over the length of the board. I think it'll make into a spectacular stock.
