Japanese Spade-End & Baitholder Hooks
Thin-gauge, high-carbon steel hooks built to Iseama pattern traditions. The spade-end 2601 and baitholder 9937DB — two designs developed in Japanese freshwater angling, adapted by European carp anglers for their light weight and secure bait presentation.
Default coating: 24K Gold — 250h ASTM B117. All five coating technologies available on request.
High-carbon steel, 78-88HRC
#12 – 3/0

Where Iseama Patterns Come From
The Iseama pattern originates in Japanese freshwater fishing — specifically targeting hera (Japanese crucian carp) in still-water venues where subtlety of presentation determines success. The defining characteristics of the Japanese hook tradition — thin-gauge, high-carbon steel wire and compact proportions — developed because hera have small, soft mouths and will reject a bait if they feel the weight of the hook.
European match and carp anglers adopted the Iseama pattern for the same reasons. The thin wire penetrates with less resistance, the compact shank keeps the hook weight low, and the spade end allows a direct line-to-shank connection that transmits bites instantly. Today, Iseama models are common in European competition tackle boxes alongside traditional European patterns.
Japanese Hook Design Principles
- 01 Thin-gauge wire — less mass to move on penetration, lower visibility in clear water
- 02 Compact proportions — shorter shank, smaller overall footprint than equivalent European sizes
- 03 High-carbon steel — hardness compensates for thinner wire; resists straightening despite smaller diameter
- 04 Micro barb as standard — Japanese tradition favors controlled barb size for secure hold without excessive tissue damage
Spadeend 2601 & Baitholder 9937DB
Spade End — Direct Line Connection
A spade-end hook has no eye. Instead, the shank end is flattened into a paddle shape. The line is whipped directly to this flattened shank using a spade-end knot — the whipping creates a straight, inline connection that transmits every twitch and bump through the line. There is no metal ring to add weight or create a pivot point. European match anglers prefer this for shy-biting fish in clear, still water.
- ▸ No eye weight — the hook sinks at the bait's natural rate
- ▸ Inline line-to-shank connection — direct bite transmission
- ▸ Model 2601, sizes #12 to #4, micro barb
Baitholder — Barbed Shank for Soft Baits
The 9937DB baitholder has small barbs cut into the shank itself — not just the main hook point. These shank barbs grip soft baits (maggots, casters, paste, pellets) and stop them sliding down toward the bend during the cast or in current. The Chinu Ring eye — a small ring welded to the shank — lets you swap pre-tied rigs without re-tying. This model is widely used in European feeder and method feeder fishing where bait security between casts matters.
- ▸ Barbed shank locks soft bait — less re-baiting between casts
- ▸ Chinu Ring eye — fast rig changes without cutting line
- ▸ Model 9937DB, sizes #10 to #2, medium-long shank
Thin Wire That Holds
The Iseama pattern uses high-carbon steel hardened to 78–88HRC. This lets us draw wire thinner than equivalent European gauge hooks while maintaining tensile strength. A thinner wire penetrates faster with less resistance from the fish's mouth — important for species like carp that can detect and eject a hook in a fraction of a second. Batch tensile testing is done per production run: sample hooks are pulled to failure and recorded.
- ▸ 78–88HRC high-carbon steel — hardness offsets thinner gauge
- ▸ Batch-tested tensile and point sharpness per production run
- ▸ All five coating technologies available; default is 24K Gold at 250h salt spray
