That clean, crisp jerk, on general sale. JetChaser sizes 3.0 and 3.1, shipping late September
Winter tip-run: fewer squid, but bigger. With the development-stage JetChaser 3.1 (24g), Keystone evangelist Azuma lands good fish exactly as pictured. When the bites went quiet he sized down to the 3.1, worked it, and the hits came one after another. “A clean, crisp jerk”, “the start of the movement is even sharper than the DayBreak 3.3”. In late September 2026 that JetChaser gains sizes 3.0 and 3.1.

About sizes 3.0 and 3.1
In late September 2026 the JetChaser gains sizes 3.0 (22g) and 3.1 (24g), and general sale begins. They are the step up that was often asked for: the larger body carries more buoyancy and brings the balance closer to the ideal. Until now the 3.1 was sold in small lots under REVOLT®, its shape settled with the help of the people who used it. On a mid-December 2024 tip-run trip, Keystone evangelist Azuma fished the development-stage 3.1 and landed good fish exactly as pictured. In winter the squid drop into deeper water: fewer, but bigger. Unlike autumn, the jerk is gentle. He started on the DayBreak 3.3 (35g) and 4.0 (39g), then sized down to the 3.1 when small ones were about — “the bites had gone quiet, but when I worked the JetChaser they came.” A few more jerks to get their attention, and a good one on the 3.1 in Laguna Chase.

The sizes, and the REVOLT road
Sizes 3.0 (22g) and 3.1 (24g) add a comfort in handling that 2.5 and 2.6 cannot give. The “clean, crisp jerk” and “sharp start” Azuma describes come from that 24-gram initial speed, and its places are early autumn, and the deep water of winter.
The head shape differs by size: 2.5 and 3.0 have a flat face that deliberately takes the water's resistance, so in shallow water, or when casting from a boat that is not drifting to cover ground, the egi does not come back towards you so quickly and can be worked slowly. 2.6 and 3.1 have a head that cuts the water, for anything from shallow to deep. The 3.1 that day was the latter. Usable from autumn through to early spring.
That day's trip falls partway through one of REVOLT®'s cycles. REVOLT is a private brand that brings the iteration loop of software development into tackle: products at the alpha and beta stage are sold direct in very small batches, and what the people who use them say goes straight back into the specification. Size 3.1 took that road — the prototype was first shown in October 2024, in the 25th-anniversary campaign; this trip followed that December; a limited colour was sold at the KEEPCAST venue in March 2025. And this autumn it reaches general release.
So the line that comes up every time a squid is landed — “and it came on the prototype” — is not just a remark. It is spoken while the REVOLT sequence is turning: put it in people’s hands, and feed the result back into the spec. Daybreak 4.0, fished the same day, was at that point still at the “it should be out in January or February next year” stage, and it reached the market first, as its product page shows.
The Lure's Role
JetChaser (size 3.0 / 3.1)
Size 3.0 is 22g, size 3.1 is 24g. Shipping starts late September 2026. Until then the 3.1 was sold in small lots under REVOLT®, taking shape with feedback from the people who fished it. The body is hard urethane foam, a material that is difficult to mass-produce, and it is that high buoyancy which makes the tension-stay posture possible. The crown hook is KS06. The series is designed to take the mask sinkers sold by various makers, so in deep water or fast current you can add weight to it.A tiny body, a high-buoyancy material, a purpose-designed crown hook. When these three depend on one another, they produce an action and a fall balance you have never experienced.
Azuma describes 3.1 as “the egi weighs 24g, so the clean, crisp feel through the jerk is the appeal” and “sharper off the mark than the Daybreak 3.3”, and names early autumn and deep water in winter as where it belongs. In practice it went on after sizing down when the bites had drifted away, and hits followed one after another from there. The colour is Laguna Chase. A good one came to this lure too.
Daybreak (size 3.3 / 4.0)
These are the sizes fished the same day, and they set the scale against which 3.1 is read. The 3.3 weighs 35g; the 4.0 pairs a 39g fast fall with an extra-heavy stainless KS size 10 hook. It is designed to reach the bottom quickly without the posture collapsing, even in hard current or strong wind, and what the 4.0 has in mind is the big spring squid — the Red Monster.
Late in the session, going up in weight to the 4.0 produced one. When the scene changes, the side that sinks fast and shows the lure on the bottom becomes the answer. Because 24g, 35g and 39g share the characteristics out between them, you can assign them to conditions — that is what carrying the series gives you. The light side gets you noticed through movement; the heavy side sinks fast and shows the lure on the bottom. This day laid both of those out inside one day.
From the Workshop in Arita
The egi used in this video are genuine made-in-Japan products, crafted at KEYSTONE's own factory in Arita, Saga Prefecture — the town of Arita porcelain. We put our soul into each and every egi.
REVOLT’s very-small-batch selling works because development, production and sales all happen in one place, in Arita. Splitting density and buoyancy across the rigid urethane foam moulding, and changing the umbrella hook for each size, happen in that same factory.
MADE TODAY IN ARITA
The fishing above is what this video records: a mid-December 2024 tip-run trip, eight minutes and twenty-seven seconds. Azuma lands good fish on the development-stage 3.1, saying “and it came on the prototype” each time. The “clean, crisp jerk” and the sharpness off the mark can, for now, only be checked in this footage.
