Our classic BUTTERKNIVES models are designed modular. For you to bring out your individual style. Start with the original BUTTERKNIFE shape, and add your choice of base and designs to create the setup that fits your board.
The BUTTERKNIVES thruster models are the first releases of Knives. This fin model earns its name from its shape. The fin has a slightly bolder tip and a wide base. The build of the fin allows for more hold during your turns. The wide base provides a lot of drive and stability. The bolder tip of the BUTTERKNIFE fin allows for extra grip.
All our setups are modular, so you decide the designs you choose. And when you damage or lose a fin, you can simply order a replacement fin. This will save you $$$ and the waste of quality fins.
Inside of the BUTTERKNIFE fin there is a honeycomb construction. This hexagonal foam core mat reduces the resin content, making the fin lighter while maintaining the desired flexibility.
The BUTTERKNIVES fins are positioned in a thruster setup. The tri-fin thruster has been the favorite fin setup of beginners and of many pros. With two fins up front and one rear fin makes the setup very versatile and strong in a wide range of conditions.
