CSE Butter Knife Design

The CSE Butter Knife with its classic outlines, perfect performance longboard rockers and well-thought-out volumes is a winner across the board. Suitable for all abilities, surfers get to ride these as single fins in the smaller conditions and discover its nose riding potential. And when it gets a bit punchier, you can just slip in the side bites and you have a perfect riding board for just about all conditions. As a thruster, a Butter Knife is balanced and predictable. Pop in a quad set up and use a bucketload of speed and increased bite to your advantage.

CSE Butter Knife Fin set up

The CSE Butter Knife comes with a 4+1 fin configuration allowing you to get creative in your setup. Try a quad, thruster, or even a single fin. NSP positioned the Surf 10 fin box slightly further back on purpose, making a realistic thruster setup work out as well.

All Butter Knives come with FTU fin boxes and are compatible with Futures® Fins (fins not included).

    Who’s the CSE Butter Knife for


    Riders looking for a mini-mal with a deeper performance envelope are well-advised to check out the Butter Knife. With its classic outlines, perfect performance longboard rockers and thought-out volumes, the Butter Knife is a shape for riders of all abilities looking for a mid-length that works and performs on smaller days.
