OVERVIEW

The A-PEN 90 packs everything a pencil bait needs into a compact 90 mm body. It walks with ease, gliding from side to side at the lightest touch of the rod, while a large rattle weight in the rear of the body knocks out a loud, cracking sound that calls hungry predators from a distance.

The same weight gives it astonishing casting distance, so you can make precise casts to active fish far away. A bullet-shaped body with a rounded-triangle cross-section balances long casts with a crisp, responsive action, and its realistic face doubles as a natural bite marker.

“A walking stickbait built for trophy peacock bass.”

Long casts, a tail-down resting angle for an instant start and a low-frequency one-knock sound: the A-PEN began as a request from the Amazon.

PERFORMANCE

ACTION & DESIGN

A one-knock sound that carries

A large rattle weight in the rear of the body knocks hard on every movement, producing a sharp, cracking one-knock sound that travels across the water and draws fish-eaters from a wide area.

Inside, a tungsten weight-transfer ball strikes a fixed steel tail ballast. Bone ABS colours give a louder knock, while clear ABS colours give a more muted thud for wary fish.

Astonishing casting distance

The weight placement that creates the sound also makes the A-PEN 90 fly. It reaches far-off feeding fish with precise, accurate casts, so you can work water that other topwater baits can't reach.

Effortless walk-the-dog

The body is shaped so that the head swings at the slightest input, making walk-the-dog easy even for beginners. Designed for big Amazon peacock bass, it keeps walking even when tied to an 80 lb fluorocarbon leader.

Bullet shape, rounded-triangle cross-section

A bullet-shaped body with a rounded-triangle (onigiri) cross-section balances long casts with quick action response. The realistic face, modelled on small carp and shiners, gives predators a clear point to aim their strike at.

Built for the Amazon

An ABS shell reinforced with internal truss bulkheads stands up to powerful fish, and the buoyancy is set so the A-PEN 90 rests tail-down, ready to start instantly, even with heavy saltwater trebles fitted.

DEVELOPMENT

BORN ON THE AMAZON

From a hand-carved pencil to a world-standard one-knocker

The A-PEN began with a request from Hiro-san, president of ADUSTA's Brazilian distributor Marine Sports, for a walking stickbait for trophy peacock bass: long casts, a tail-down resting angle for an instant start and a low-frequency one-knock sound. Lure designer R. Nakanishi went back to a 120 mm basswood pencil bait he had hand-carved and refined as a student, with a rounded-triangle cross-section and a slightly tail-heavy balance, and remade it in ABS at 90 mm.

In summer 2017, early prototypes were tested for four days on the Teles Pires River, an Amazon tributary, where sound proved to be the single most important factor. Dozens of internal layouts later, the balanced final design combines an ABS shell with truss bulkheads, a tungsten weight-transfer ball that strikes a steel tail ballast, and a rattle chamber in the nose.
