Skiving is a relatively straightforward metal working technique, and it is very similar to the act of hand planning a block of wood except that the 'shavings' are shorter and remain attached. The benefit of a skived heatsink has always been the lack of a thermal joint between the fins and base, since each is formed from the same block of raw material. In this case, the skived fins on this Cooljag heatsink are particularly long (58mm) though.

One of the design elements incorporated into the Cooljag SFO-D(18SC) is a section of the skived fins being swept back. This helps reduce back pressure and promote even airflow through the fins.
