An unique barrel that features both characteristics of straight and torpedo.
Macau's TRiNiDAD player, Lourenco Sun Model.
At the back end of the barrel, ring cuts are applied to prevent any grip misalignment. Although sharp shark cuts were placed afterwards, ring cuts are placed in between the shark cut to tone down the edginess.
One can grip the straight section of the barrel near the back or can choose to grip at the center area and utilize the torpedo section near the front as well.
It may be hard to imagine from its unique shape, it is a barrel that boasts high controllability.
