The Mustad 3713 B Carlisle Hook represents a specialized bait pattern from O. Mustad & Son's Oslo factory, packaged in a rigid manufacturer box containing 100 size 5 hooks. The model employs a blind marked shank construction \u2014 a feature almost entirely confined to British and Scandinavian bait-fishing traditions \u2014 combined with a 4X long shank and narrow gap. The blind design eliminated the need for a formed eye, instead relying on lateral ridges cut into the shank to grip leader material, gut loop, or snell attachment.<\/p>
The Carlisle bend itself is a deep, rounded form derived from 19th-century English traditions, producing a closed mouth that resists bite-offs. The hollow point provides a sharp, inwardly-curved tip geometry favored for penetration in soft-mouthed fish species. The kirbed (left-offset) point is consistent with bait hook design of this era.<\/p>
Dating evidence includes the absence of a barcode, letterpress printing in gold on cream stock, the decorative frame-style label layout, and the \"OSLO - NORWAY\" address format characteristic of Mustad's pre-1960s packaging. This model sits at the tail end of the blind-eye era in commercial hook production, as formed-eye alternatives increasingly dominated market offerings by the 1950s.<\/p>
The 3713 B remains uncommon in complete original packaging, particularly in this early box format. Collector appeal derives from the documentation of a specialized construction technique and the ephemeral nature of manufacturer boxes relative to the far more abundant sales card format.<\/p>","spec_bar_items":"Blind Eye\nCarlisle\n4X Long Shank\nHollow Point\nBronzed","flyhooks_url":"","svg_filename":"Mustad_3713_B_Hook_Size_5.svg","filebird_folder_id":720,"flies_tied_on_folder_id":"","eye_type":"blind_marked","eye_orientation":"na","eye_notes":"","wire_gauge":"std","wire_profile":"round","wire_diameter_est":"","shank_length_category":"long_4x","shank_features":["marked_ridged"],"bend_family":"carlisle","bend_notes":"Carlisle bend exhibits deep rounding through the turn, with no angular flattening at the bottom.

The blind marked shank is the defining technical feature. Rather than forming an eye loop at the hook end, Mustad cut lateral ridges or grooves into the shank material itself, creating mechanical grip for snell attachment. This construction method reduced material volume at the critical stress junction and simplified manufacturing \u2014 no secondary eye-forming operation was required. The ridges act as teeth, preventing the snell or gut loop from sliding along the shank during fighting or setting.<\/p>
The 4X long shank classification indicates a shank length approximately four times the gap width \u2014 a ratio optimized for bait presentation and for accommodating larger baits (worms, insects, small fish) without excessive overhang. Narrow gap with long shank forces the point inward relative to the shank plane, creating a bite angle that favors penetration in cartilaginous mouth structures common to bottom feeders and soft-mouthed species.<\/p>
Hollow point geometry produces an inwardly-curved inner face from barb to tip, forming a small concave depression. This knife-edge effect concentrates cutting force at the smallest possible contact area, reducing the force required to penetrate tissue \u2014 a significant advantage in bait fishing where fish may mouth the hook before fully committing. Standard round wire profile distributes stress evenly through the bend, a deliberate engineering choice for durability in rough-ground and weed fishing where hooks encounter abrasion.<\/p>
The bronzed finish was the industry standard for bait hooks of this era. The warm brown tone provided mild corrosion resistance adequate for freshwater use, and the slightly rougher surface compared to nickel offered modest improvement in snell grip and visibility in murky water conditions.<\/p>","hook_ply":"single","barbless":false,"measurements_available":true,"measurement_method":"physical_caliper","size_measured":"5","overall_length":"~1.36\" (~34.4 mm) (P)","shank_length":"~1.22\" (~30.9 mm) (P)","gap_width":"~0.29\" (~7.4 mm) (P)","bend_depth":"","wire_diameter_measured":"~0.03\" (~0.8 mm) (P)","shank_gap_ratio":"","weight":"","measurement_notes":"Overall length: 13.56 sq = 1.356\".

O. Mustad & Son was founded in Oslo, Norway, in 1832 by Olaf Mustad. The company established itself as a major industrial hook manufacturer through the 19th century, gradually dominating both Scandinavian and British market segments. Unlike the Redditch craft tradition, which relied on artisan workshops and smaller manufacturing runs, Mustad adopted integrated factory production and aggressive global distribution, making quality hooks accessible at volume.<\/p>
By the early 20th century, Mustad's Gj\u00f8vik facility (in addition to Oslo operations) had become the largest single hook manufacturer in Europe. The company maintained direct sales relationships with major British tackle dealers and fishing supply houses, allowing Norwegian-manufactured patterns to compete effectively against Redditch-made hooks. This dual-market positioning \u2014 competing on price and consistency while maintaining design ties to English traditions \u2014 proved strategically effective through the mid-20th century.<\/p>
The blind-eye hook, though primarily associated with British makers like Allcock and Partridge, was manufactured by Mustad for export to UK anglers and dealers who demanded these specialized patterns. The 3713 B Carlisle represents this cross-market production strategy: a pattern with English geometric heritage, manufactured in Norway, and distributed internationally.<\/p>","series_history":"
The Carlisle bend family has roots in 19th-century English river fishing traditions, where the deep rounded mouth was preferred for grayling, dace, and other soft-lipped species. The form appears in tackle catalogs as early as the 1870s from English makers. Mustad's adoption of the Carlisle geometry reflects the company's strategy of offering parallel patterns to established British designs, capturing price-sensitive customers while maintaining design legitimacy through recognized bend families.<\/p>
The blind-marked variant (3713 B) indicates production specifically for snelled-hook markets and gut-loop attachment methods. These specialized bait hooks occupied a distinct segment from the 1920s through the 1950s. Blind-eye construction offered practical advantages: the elimination of a formed eye reduced stress concentration points, and the ridged shank provided mechanical grip superior to smooth shanks in certain applications.<\/p>
By the 1960s, as nylon monofilament and modern formed-eye attachment methods became standard, blind-eye production declined sharply. The 3713 B was eventually displaced by formed-eye Carlisle variants and ultimately discontinued as market demand shifted entirely to modern eye geometries. This model represents a transitional artifact \u2014 a link between 19th-century bait-fishing practices and mid-20th-century modernization.<\/p>","named_collaborator_bio":"","era_dating_reasoning":"Box construction and letterpress printing are consistent with 1930s-1950s manufacture.

Anglers of the 1930s-1950s would have prepared the snell by tying a loop knot in a length of strong gut or early nylon, then threading the loose end through the ridged shank and securing it with thread or waxed silk. The lateral ridges acted as mechanical teeth, preventing slippage during the fight. With the widespread adoption of modern monofilament and mass-produced formed-eye hooks in the 1960s, this entire skill set \u2014 the tying of gut loops, the interpretation of ridge patterns, the judgment of gut diameter for specific shank sizes \u2014 became unnecessary and was largely forgotten.

The Carlisle bend traces its lineage to 19th-century English river-fishing traditions, where the pattern appears in tackle catalogs and angler notebooks from the 1870s onward. English makers \u2014 particularly Allcock and smaller Redditch specialists \u2014 refined the deep-rounded mouth geometry specifically for grayling and dace fishing, species with soft mouths that required a more closed bite profile than the standard Sproat or Round Kendal patterns.<\/p>
Mustad's adoption of Carlisle geometry reflects the company's broader strategy: Norwegian industrial production capacity coupled with English design legitimacy created competitive advantage in export markets. By offering parallel geometries to established British patterns, Mustad could undercut Redditch prices while maintaining design familiarity. The blind-marked variant (3713 B) is specifically Mustad's interpretation of this cross-market strategy \u2014 a pattern derived from English tradition but engineered for Norwegian manufacturing methods.<\/p>
Competing designs from other manufacturers include Allcock's own Carlisle patterns (typically in forged wire and with formed eyes rather than blind shanks) and Partridge of Redditch's sneck and round-bend variants. The British versions maintained stronger attachment to snelled-hook markets and gut-loop construction throughout the 1950s, while Mustad's industrial production approach positioned the 3713 B for volume distribution to tackle dealers serving price-conscious anglers.<\/p>
By the 1960s, the blind-eye category declined sharply as modern nylon monofilament and formed-eye attachment methods became universal. The Carlisle bend itself survived this transition in other formats (notably the Mustad 34007, a more modern long-shank Carlisle with a ball eye), but the blind-marked variant represents an evolutionary dead-end \u2014 a specialized tool made obsolete by broader shifts in fishing tackle standardization.<\/p>","related_models":null,"primary_application":"","secondary_applications":"","fly_patterns":"Named patterns specifically associated with this hook.
