Gamakatsu Model 02311 — Octopus Hook, Size 1/0, Red Finish
A modern general-purpose bait hook manufactured by Gamakatsu (Japan, made in Japan and packaged in Thailand). The size 1/0 Octopus is defined by its sproat bend, needle point, turned-up tapered eye, and distinctive bright red epoxy finish. Designed for live and prepared bait fishing across freshwater and light saltwater applications.
The 02311 represents late-20th-century mass-market hook production, evidenced by the modern packaging design with thermoplastic clamshell blister card, safety warning statement, and US address (Tacoma, WA). No barcode is visible on the package front, consistent with production in the 1990s-early 2000s era. Gamakatsu’s entry into the North American market in the 1980s-1990s made this hook widely available in retail tackle shops.
Collecting significance is modest — Gamakatsu octopus hooks in all sizes remain common and continue in production. Size 1/0 is particularly abundant due to its versatility. Value is driven primarily by package format and condition rather than scarcity or age.

Gamakatsu 02311 | Size 1/0 | Sproat Bend | Turned-Up Tapered Eye | Needle Point | Red Epoxy Finish | Standard Shank, Standard Wire
The sproat bend provides a rounded hook point with moderate depth — balancing hook-setting strength against wire flexibility. The needle point delivers sharp initial penetration suitable for soft baits (earthworms, shrimp) and live-bait presentations where bait resistance is minimal. The turned-up tapered eye allows consistent line-to-hook-shank angle and provides convenient knot-tying access. Standard wire gauge (approximately 0.055-0.065 inches) balances holding strength with compatibility with light to moderate tackle and bait sizes. The red epoxy coating is functional (corrosion resistance in saltwater and freshwater) and visual (improves bait visibility and hook recognition in tackle boxes).

Gamakatsu Co., Ltd. is a Japanese fishing tackle manufacturer founded in 1955 in Chuo Ward, Chiba Prefecture, Japan. The company is a global producer of fishing hooks, with manufacturing facilities in Japan and distribution throughout North America, Europe, and Asia. Gamakatsu entered the North American market in the 1980s, establishing Gamakatsu USA Inc. with headquarters in Tacoma, Washington. The company is known for high-volume production of modern hook designs at competitive prices, serving both recreational and commercial fishing markets. Gamakatsu’s product range spans freshwater bait hooks, saltwater patterns, fly-tying hooks, and specialized terminal tackle.
The Gamakatsu Octopus (model 02311) is a continuous-production bait hook with no defined historical series — it is a standalone model within Gamakatsu’s general-purpose bait hook line. The octopus-style sproat bend is a classic hook geometry used by numerous manufacturers globally, and Gamakatsu’s version represents a modern iteration aimed at cost-sensitive retail markets. The red epoxy finish is characteristic of Gamakatsu’s mass-market offerings, providing visibility in water and differentiation in retail displays. No documented design changes, discontinuation, or predecessor/successor model variants are known for the 02311.
Modern thermoplastic clamshell packaging typical of 1990s-2000s retail production. Absence of barcode suggests pre-1974 is incorrect for this modern product — no barcode typical of early blister pack era (1970s-1980s). Typography and Tacoma, WA address consistent with Gamakatsu US market entry period (1980s onward). Safety warning statement and manufacturing labeling style typical of 1990s-2000s US retail regulations. Paper stock and offset print quality consistent with modern mass production, not vintage Redditch or pre-1970s manufacturing.
The Octopus hook name derives from the hook's original use in bottom-feeding techniques where the wide gap and short shank mimicked the profile of an octopus or squid — common prey for bottom-feeding species in saltwater and brackish environments. Gamakatsu's red epoxy finish became a signature visual marker of the brand in North American tackle shops, making these hooks instantly recognizable to recreational anglers. The 02311 bulk packaging (25-, 6-, and 100-pack options documented) reflects Gamakatsu's strategy to serve both retail and commercial bait shops with a simple, efficient product.
The octopus/sproat bend geometry predates Gamakatsu by decades, originating in 19th-century Redditch production as a general-purpose hook for bait and live-bait fishing. The modern Gamakatsu 02311 represents the industrialization of this classic design — simplified manufacturing, reduced cost, and mass retail distribution. No documented direct predecessor or successor within the Gamakatsu line; the 02311 has remained in continuous production since the 1990s without major revisions.

| Hook | Match Quality | Notes |
|---|---|---|
| Gamakatsu 02311 (current production) | Excellent | This model remains in continuous production with no design changes. Modern 02311 packages are functionally identical to the specimen documented. |
| Mustad 92247 Big Red Octopus | Very Good | Nearly identical sproat bend, needle point, similar size/wire gauge profile. Red finish comparable. Alternative from major competitor. |
| Owner 5109 Octopus | Good | Octopus geometry with similar applications, slightly finer wire. Japanese manufacturer equivalent. |
Rated 2.0/10 — Gamakatsu octopus hooks remain in active production and are abundant in the secondary market. Size 1/0 is the most common size due to its versatility. Collector demand is negligible; these are functional bait hooks picked up opportunistically rather than actively sought by specialists.
Positive factors: Complete 100-pack sealed or near-sealed in original packaging is visually appealing and represents excellent bulk value to bait anglers and tyers. Red finish is visually distinctive. Gamakatsu brand has recognition among modern tackle collectors.
Limiting factors: Gamakatsu octopus hooks in all sizes remain in continuous production and are stocked by major retailers (Amazon, Cabela’s, Bass Pro Shops, eBay) at low prices. No rarity — thousands of specimens exist in unopened packages. No historical significance or vintage character; modern production (1990s-2000s onward). Size 1/0 is the most versatile and therefore most common size produced. Packaging is modern generic clamshell format with no distinctive printing or construction merit. Individual loose hooks have minimal specimen value given the high production volume and ready availability.
Desirable variants: Sealed original 100-packs command a modest premium over loose hooks or opened packs. Packaging condition (printing clarity, blister integrity) affects value. Alternate sizes (particularly size 10 or larger specialty finishes, if produced) might carry marginal premium, but no documented size variants of note exist.
Condition factors: Hooks showing no corrosion or discoloration are standard expectation; any rust or patina reduces value. Card/packaging showing heavy creasing, printing fade, or damage reduces appeal. Missing hooks (common in second-hand packs) reduce value proportionally.

Store the sealed clamshell blister pack in a cool, dry environment away from direct sunlight and humidity. The red epoxy finish provides excellent corrosion resistance, but prolonged humidity exposure may cause minor surface oxidation (bloom) on the steel beneath the coating. Keep original packaging intact — do not remove hooks unless planning to use them for fishing. If the pack is opened, store remaining hooks in the original blister or transfer to a resealable plastic bag with a desiccant packet (silica gel) to prevent moisture accumulation. Avoid contact with other metal tackle (lead sinkers, brass swivels) to prevent galvanic corrosion. Opened packs should be stored away from saltwater environments (garage, shed near coast) where salt spray accelerates oxidation. For long-term specimen preservation, maintain constant temperature (65-75°F) and relative humidity (30-40%) to prevent condensation and corrosion cycles.

Manufacturer Attribution: The printed header states ‘Gamakatsu’ with registered trademark (®) symbol and script logo. The lower text block identifies ‘GAMAKATSU U.S.A. INC.’ with address ‘P.O. BOX 1797 TACOMA, WA 98401’ — establishing the US distributor office.
Manufacturing and Origin Claims: The package explicitly states ‘HOOKS MADE IN JAPAN’ and ‘PACKAGED IN THAILAND’ — a two-stage production model typical of modern Asian fishing tackle. The hooks are forged and finished in Japan (Chiba Prefecture, Gamakatsu’s main facility), then packaged and distributed from Thailand. This split-source approach reflects cost optimization for the North American retail market.
Safety and Regulatory Compliance: The card includes a blue-printed WARNING statement: ‘HANDLE WITH CARE. EXTREMELY SHARP. KEEP OUT OF REACH OF SMALL CHILDREN.’ This warning label format is consistent with US Consumer Product Safety Commission (CPSC) requirements and FDA labeling standards for fishing tackle, typical of late-1990s-2000s product certification. The prominent placement and all-caps treatment indicate compliance with regulatory guidelines enforced during this era.
Quantity and Stock Identification: The 100-pack format with model code 02311-100 is specifically designed for bulk retail distribution and professional/charter boat supply chains. The ‘100’ suffix in the stock code identifies this as the largest package option (vs. 02311-6 or 02311-25).
