Butter Knife HDT Design

When it comes to Carl’s mini-tank designs, the Butter Knife with its classic outlines, perfect performance longboard rockers and thought-out volumes is a winner across the board. Suitable for all abilities, ride them as single fins in the smaller conditions and let its nose riding capabilities surprise you. And when it gets a bit punchier, slip in the side bites and you have a perfect riding board for just about all conditions.


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

The Butter Knife HDT is a Carl Schaper creation and comes with FTU fin boxes, which are compatible with Futures® Fins (fins not included).

HDT Construction

Butter Knife HDT construction diagram

NSP’s High Definition Technology (HDT) construction redefines the boundaries of surfboard manufacturing. It is now possible to have a board that is incredibly tough, lightweight and high-performance at an affordable price.

Created specifically for the Shapers Union range, HDT pairs high-performance designs with precision moulding technology, ensuring accurate reproduction and dynamic flex characteristics. HDT uses a model-specific, fully fused and water-resistant SecureCell EPS Core, military-grade fibreglass and foaming epoxy resin. Moulded in NSP’s high-tech vacuum moulds, this reduces waste and environmental impact of a traditionally produced surfboard by 30%.

HDT also creates an exceptionally durable shell that offers unmatched strength and lightweight performance, with 50% higher breakage strength at a lower weight than similar boards built in PU.

Implemented at the request of some of the world’s best board builders in the Shapers Union, NSP HDT construction provides consistent performance and durability session after session, elevating the surfing experience with premium materials and innovative technology.
