Butter Knife Design

The Nature Flex Butter Knife with its classic outlines, perfect performance longboard rockers, and well-thought-out volumes is suitable for all abilities. Surfers get to ride these as single fins in the smaller conditions and discover their 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 setup and use a bucketload of speed and increased bite to your advantage.


Butter Knife Fin setup

The Butter Knife comes in three sizes and a 4+1 fin configuration enabling you to be creative in your setup as a quad or thruster. NSP positioned the Surf 10 fin box slightly further back to make it available for a thruster set-up

Available with FTU fin boxes and are compatible with Futures Fins (fins not included).
