Product Information

Full details

The Deflow Surf Pocket Knife 7.5-inch fin is designed for intermediate to advanced surfers looking to balance stability with high-performance maneuverability on boards ranging from 6 feet to mid-7 feet. It serves as a versatile choice for both dedicated single-fin setups and 2+1 configurations, providing a stiff flex pattern that ensures predictable responses during vertical turns; however, riders accustomed to highly flexible or pivot-heavy traditional longboard fins may find the stiffer construction requires more deliberate engagement.

FAQs

Can I use this fin on a 9-foot longboard?

While it can technically fit, it is specifically optimized for boards between 6 feet and mid-7 feet; it may lack the surface area needed for optimal hold on a larger traditional longboard.

Is this fin better for single fin or 2+1 setups?

It is designed to be highly effective in both configurations, offering a balance of drive and release regardless of the setup.

Does it come with a screw and plate?

Standard Deflow fins usually require a standard fin screw and plate, which are typically sold separately or included with your surfboard's fin box hardware.

What material is this fin made of?

The Pocket Knife is part of the Core Collection, utilizing high-quality materials designed for a stiff, performance-oriented flex.

How should I position the fin in the box?

Start with the fin in the center of the box for a balanced feel. Move it forward for a looser, more pivot-oriented feel or backward for more hold and drive.

Troubleshooting

Fin feels loose in the fin box

Ensure the screw is fully tightened and the brass plate is properly seated against the underside of the box lip.

Fin base is difficult to insert

Check the fin box for sand or dried salt and clear it using a small brush or fresh water.
