NA split 4 (10′/11′): custom profiling & sharpening by mail

NA Split 4 (10′/11′)

The NA Split 4 uses a 10′ front radius and an 11′ rear radius, making it a more neutral, balanced split profile. Compared with NA Split 3, it shifts slightly away from pure quickness and toward a more familiar, stock-like feel with a bit more support and glide.

Like the other split profiles, it uses two different radius shapes on the middle section so the front and rear of the blade can do slightly different jobs. SSM explains that the smaller front radius helps with mobility and acceleration, while the larger rear radius adds support and pressure. That mix makes the profile feel balanced and easy to adapt to, especially for players who want some split-profile benefit without going too far in one direction.

Among your product lineup, NA Split 4 works well as a middle-ground option. It has enough quickness to feel active, but it stays more neutral than NA Split 3 and doesn’t push as hard toward speed/stability as your flatter or longer profiles.

Acceleration 3/5 · Deceleration 3/5 · Agility 3/5 · Speed 3/5 · Stability 3/5
