The concave geometry creates a fine, razor-sharp tip that flares rapidly toward the barb, concentrating penetration force without creating an oversized entry wound that might tear free during the fight. For trout and grayling, this geometry is ideal because these soft-mouthed species require a touch-and-hold approach rather than a violent set.\r\n\r\nThe forged shank dramatically increases structural rigidity and tensile strength relative to unforged wire of the same gauge. Cold-forging flattens the cross-section along the lateral axis, creating an oval or slightly flat profile. This increases resistance to bending and straightening under load without adding significant material mass. For a 4X-long shank like the 9513, forging is essential \u2014 the extended length would otherwise flex excessively during casting or when landing larger fish.\r\n\r\nThe tapered eye reduces frontal weight and streamlines the profile at the head of the fly. This is particularly important for streamer patterns, which must achieve a balanced, horizontal float or controlled sink rate. A full ball eye (standard on economy hooks) adds unwanted bulk that causes the fly to dip nose-first or rotate erratically. The tapered eye allows the tie materials (fur, feather, tinsel) to balance the mass of the hook itself, resulting in a more lifelike, hydrodynamic presentation.\r\n\r\nThe Viking bend geometry is a carefully engineered hybrid \u2014 not quite as angular as a Limerick (which locks jaw position in the lowest, strongest point of the bend) and not as fully round as an Aberdeen (which distributes load more evenly but offers less mechanical advantage during the fight). The Viking's moderate curvature distributes stress across the bend while maintaining sufficient depth to resist straightening. This balance made it the preferred choice for streamer tying, where durability and casting comfort were equally important.","hook_ply":false,"barbless":false,"measurements_available":true,"measurement_method":"physical_caliper","size_measured":"10","overall_length":"~0.71\"-0.75\" (~18.0-19.0 mm) (P)","shank_length":"~0.58\"-0.64\" (~14.7-16.3 mm)","gap_width":"~0.19\"-0.23\" (~4.8-5.8 mm) (P)","bend_depth":"~0.32\"-0.38\" (~8.1-9.7 mm)","wire_diameter_measured":"","shank_gap_ratio":"~2.8-3.0 : 1","weight":"","measurement_notes":"Overall length: 7.2 small squares = ~0.72\".

Mustad &amp; S\u00f8n was founded in 1832 in Gj\u00f8vik, Norway, initially as 'Brusveen Spiger- og Staltradfabrikk,' producing nails and steel wire. The company was taken over by Hans Schikkelstad's son-in-law, Ole Hovelsen Mustad, and his son Hans Mustad, who rebranded it as O. Mustad &amp; S\u00f8n. The pivotal moment came in 1877 when Mathias Topp, a visionary engineer within the company, invented the first fully automated hook-making machine \u2014 a watershed innovation that allowed continuous production of cut, bent, barbed, and pointed hooks at unprecedented speed and volume. Rather than filing for patents (which would have required public disclosure of mechanical schematics), the Mustad family relied on strict corporate secrecy and restricted factory access to protect their proprietary technology. This strategy proved devastatingly effective against rival hook-making centers in Redditch, England, and competing manufacturers in Japan and the United States.\r\n\r\nBy the early twentieth century, Mustad had established itself as the world's dominant hook manufacturer. The company expanded aggressively into international markets, establishing sales offices and export operations across Europe, North America, and beyond. During the mid-twentieth century, the Norwegian capital's relocation from Christiania to Oslo (January 1, 1925) is reflected in Mustad's packaging nomenclature \u2014 labels shifted from 'CHRISTIANIA - NORWAY' to 'OSLO - NORWAY,' providing archivists with a precise chronological marker. By the 1950s, Mustad had secured approximately 50% of global hook production, making the word 'Mustad' virtually synonymous with the fishing hook itself. The company maintained manufacturing facilities in Norway and expanded production capacity to meet booming post-war demand from both commercial fishing fleets and the rapidly growing recreational fly-tying market.\r\n\r\nMustad remained a family-operated concern through much of the twentieth century, though the company's scale and global reach eventually led to diversification and modernization. Today, O. Mustad &amp; S\u00f8n AS continues as the world's largest manufacturer of fish hooks, though much of the production has transitioned from Norway to specialized manufacturing plants in Asia and other regions. The legacy of Mustad's engineering innovation and the iconic 'Key Brand' trademark remain central to the company's identity.","series_history":"The 'Mustad-Perfect' series represents Mustad's flagship quality tier for fly hooks in the mid-twentieth century. The term 'Perfect' was deliberately chosen to signal premium craftsmanship and mechanical precision. The 9513 was introduced as part of this series to serve the growing market for streamer and wet fly tying, particularly in Scandinavia and the UK, where long-bodied patterns were experiencing a surge in popularity following World War II.\r\n\r\nThe Viking bend, specific to the 9513 and closely related models, was engineered as a compromise between the rigid geometry of a Sproat (favored for nymphs and bait hooks) and the full round bend (favored for light-tackle presentations). This hybrid approach allowed tyers to achieve both structural strength and aesthetic balance \u2014 essential for the emerging discipline of streamer fishing, which demanded patterns that could withstand the violent strikes of pike, bass, and large trout while maintaining a lifelike silhouette in the water.\r\n\r\nThe 'Extra Long Shank' designation (4X) was crucial to the 9513's design philosophy. The extended shank accommodated the elaborate wing constructions typical of classic streamers (Muddler Minnow, Mickey Finn, Woolly Worm variants) without requiring the tyer to add bulk at the eye or sacrifice profile balance. The tapered eye (T.D. \u2014 Turned Down) was a marker of the 'Perfect' series' premium positioning, reducing frontal weight and allowing the fly to float or sink more predictably than hooks with heavier ball eyes.\r\n\r\nThe 'Forged' designation indicates that the shank and bend were subjected to cold-forging in a mechanical drop-press, a labor-intensive process that increased tensile strength without adding weight. This was a hallmark of Mustad's 'Perfect' series and contrasted sharply with economy hooks, which used unforged wire.\r\n\r\nThe 'Rustproof' notation on the label refers to the bronzed finish \u2014 a baked-on lacquer process that provided excellent corrosion resistance for freshwater applications. By the 1950s\u20131960s, this finish was becoming standard on premium fly hooks intended for wet-fly and streamer work, where the hook spends significant time submerged and exposed to acidic tannins in stream water.\r\n\r\nThe 9513 remained in production through much of the latter twentieth century, though it faced increasing competition from specialized streamer hooks (such as the 79580 'Viking Streamer') introduced later by Mustad. The transition to the 'Signature Series' around 2001\u20132009 effectively discontinued the 9513 and its arbitrary model number nomenclature, replacing it with more logically constructed alphanumeric codes (e.g., 'R73' for Round bend, 7X strong, 3X long). Original packaging from the 1950s\u20131960s is now recognized by collectors as a definitive artifact of this classic series.","named_collaborator_bio":"","era_dating_reasoning":"Label bears 'OSLO - NORWAY' (Line 3), confirming post-1925 production (Oslo designation adopted January 1, 1925).

American tier Don Gapen's introduction of the Muddler in 1937 spawned countless variations, and the 9513's extra-long forged shank was perfectly suited to these patterns. The hook became so closely associated with classic streamer tying that many vintage fly boxes labeled 'Streamer Assortment' contain predominantly 9513s or direct Mustad equivalents. Interestingly, the 'Reversed' notation on the label has caused confusion among modern collectors \u2014 it does not indicate a reverse-offset point (Beak-style), but rather a subtle twist in the shank axis, a manufacturing detail that helped the pattern sit naturally in the fly without excessive wing rotation.","fun_fact_title":"The Muddler Era and Streamer Revolution","manufactured_size_range":"","hook_sizes":[{"size_label":"10","size_sort_key":10,"size_documented":true,"size_confidence":"P","overall_length_mm":"","overall_length":"~0.71\"-0.75\" (~18.0-19.0 mm) (P)","shank_length":"~0.58\"-0.64\" (~14.7-16.3 mm)","gap_width":"~0.19\"-0.23\" (~4.8-5.8 mm) (P)","bend_depth":"~0.32\"-0.38\" (~8.1-9.7 mm)","wire_diameter":"","weight":"","shank_gap_ratio":"~2.8-3.0 : 1","measurement_method":"physical_caliper","svg_override":""}],"spec_bar_short":"","design_lineage":"The 9513 occupies a position in the evolutionary lineage between early round-bend streamer hooks and the specialized, dedicated streamer hooks that would emerge in the latter twentieth century. Its predecessor in the Mustad line was the earlier Viking-pattern hooks from the pre-war era, which lacked the premium 'Perfect' branding and tapered eye. The 9513 represents a conscious upgrade in manufacturing precision and material specification, responding to the booming post-war demand for quality streamer patterns.\r\n\r\nCompeting designs from other manufacturers included the Partridge of Redditch 'CS10' (Ashton Eye, Sproat-style bend) and the British 'Harrison Bartleet' hooks, which offered similar profiles but with ball eyes or blind eyes depending on the model. The Tiemco 5263, introduced later, shares the extra-long shank and forged construction but features a full round bend rather than the Viking hybrid, making the 9513 geometrically distinct even among its closest modern cousins.\r\n\r\nThe 9513's influence on downstream hook design is evident in Mustad's own later introductions, particularly the 79580 'Viking Streamer' hook, which essentially replaced the 9513 in the product line during the 1970s\u20131980s. The 79580 maintained the extra-long shank and forged wire but featured a modern ball eye and were subjected to Mustad's newer, more aggressive automated production processes. Nevertheless, the 9513's engineering principles \u2014 the balance between strength and weight, the tapered eye concept, and the Viking bend geometry \u2014 remain relevant to contemporary streamer-tying practice.","related_models":[{"model_code_related":"Qual. 9513","description":"Mustad 9513 \u2014 Mustad-Perfect Viking Hooks, Qual. 9513, Hollow Point, Forged, Reversed, Tapered Eye, Rustproof, Extra Long Shank \u2014 this entry","relationship":"this_model","related_model_url":""},{"model_code_related":"Qual. 79580","description":"Mustad 79580 \u2014 Viking Streamer Hook; successor to 9513, modernized with ball eye and updated production; later vintage era","relationship":"later","related_model_url":""},{"model_code_related":"Qual. 3906B","description":"Mustad 3906B \u2014 Wet Fly Hook, Sproat bend, standard shank; contemporary competitor pattern with round bend and ball eye","relationship":"variant","related_model_url":""},{"model_code_related":"Qual. 36890","description":"Mustad 36890 \u2014 Classic Salmon Fly Hook, Limerick bend, looped eye; heavy-duty Atlantic Salmon pattern from same era","relationship":"companion","related_model_url":""}],"primary_application":"The Mustad 9513 is designed primarily for wet flies, classic streamers, and early-season nymphs.

The concave, swept profile of a hollow point ensures rapid initial penetration with minimal applied pressure \u2014 ideal for soft-mouthed species and delicate presentations.\r\n\r\n<strong>Line 6: 'Mustad-Perfect Viking Hooks'<\/strong> \u2014 Pattern name and series identity. The 'Perfect' branding signals premium positioning; the 'Viking' designation refers to the specific bend geometry \u2014 a hybrid rounder curve engineered for the post-war streamer boom.\r\n\r\n<strong>Lines 7\u20138: 'Forged Reversed Tapered Eye Rustproof Extra Long shank'<\/strong> \u2014 Anatomical modifications and metallurgical finishes. 'Forged' indicates cold-pressing to increase tensile strength. 'Reversed' refers to subtle shank twist (not a reverse offset). 'Tapered Eye' reduces frontal mass. 'Rustproof' denotes the bronzed lacquer finish. 'Extra Long' (4X) accommodates elaborate wing constructions.\r\n\r\n<strong>Bottom corner: 'No. 10 Made in Norway'<\/strong> \u2014 Size and factory designation. Size No. 10 is a medium fly hook, suitable for nymphs and small to medium streamers. The 'Made in Norway' assertion emphasizes the Gj\u00f8vik factory provenance, a mark of quality in an era when Scandinavian and British manufacturing commanded premium pricing in North American markets."},{"acf_fc_layout":"size_anomaly","title":"Understanding Hook Size No. 10 in Historical Context","content":"Hook sizing conventions have evolved considerably over the past century, and the vintage Mustad 'No. 10' designation reflects a numbering system that differs significantly from modern standardized fly hook sizing (which uses gape measurement in millimeters). The Mustad 'No. 10' from the 1950s\u20131960s is slightly smaller in actual gape width than what might be labeled a modern 'Size 10' by contemporary manufacturers like Tiemco or Orvis.\r\n\r\nThe confirmed gap width of this specimen (0.21 inches \/ 5.33 mm) places it at the boundary between modern 'Size 12' and 'Size 10' gape classifications, depending on the manufacturer's calibration. This historical inconsistency is not an error or anomaly \u2014 it simply reflects the fact that vintage hook sizing was based on regional traditions and manufacturing convention rather than a universal gape-measurement standard.\r\n\r\nFor historical accuracy, collectors and tyers should refer to vintage Mustad 'No. 10' hooks by their original designation and understand that they may correspond to modern 'Size 12' gape in some fly tying contexts. The original numbered size on the package ('No. 10') remains the correct historical reference; do not attempt to 'correct' it to modern equivalents."},{"acf_fc_layout":"custom_section","title":"The 'Reversed' Notation Explained","content":"The word 'Reversed' on the 9513 label has caused confusion among modern collectors unfamiliar with vintage Mustad terminology. It does NOT indicate a 'reverse-offset' point (Beak-style), where the point is deflected outward from the shank axis to the right when viewed from above. Such a hook would be explicitly labeled 'Reversed Kirby' or noted separately in the product line.\r\n\r\nOn the 9513, 'Reversed' refers to a subtle manufacturing detail: the shank wire exhibits a slight twist or rotation along its length, a characteristic engineered into select premium patterns to improve the natural hang and presentation of tied patterns in the water. This twist prevents the shank from lying flat in a simple plane; instead, it creates a gentle helical bias that encourages the fly's materials (fur, feather, tinsel) to sit at a natural angle relative to the hook axis. For streamers and wet flies, this seemingly minor detail significantly improves the three-dimensional profile and makes the pattern appear more lifelike as it swings or drifts through the water column.\r\n\r\nThis feature was particularly valued in Scandinavian fly tying, where materials quality and subtle engineering refinements were viewed as markers of craftsmanship excellence. The 'Reversed' designation on Mustad hooks thus signals a premium attention to detail in the bending and forming process \u2014 not a dramatic geometric alteration like a true reverse offset."}]},"_links":{"self":[{"href":"https:\/\/garrenwood.com\/wp\/wp-json\/wp\/v2\/pages\/10628","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/garrenwood.com\/wp\/wp-json\/wp\/v2\/pages"}],"about":[{"href":"https:\/\/garrenwood.com\/wp\/wp-json\/wp\/v2\/types\/page"}],"author":[{"embeddable":true,"href":"https:\/\/garrenwood.com\/wp\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/garrenwood.com\/wp\/wp-json\/wp\/v2\/comments?post=10628"}],"version-history":[{"count":5,"href":"https:\/\/garrenwood.com\/wp\/wp-json\/wp\/v2\/pages\/10628\/revisions"}],"predecessor-version":[{"id":16788,"href":"https:\/\/garrenwood.com\/wp\/wp-json\/wp\/v2\/pages\/10628\/revisions\/16788"}],"up":[{"embeddable":true,"href":"https:\/\/garrenwood.com\/wp\/wp-json\/wp\/v2\/pages\/7980"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/garrenwood.com\/wp\/wp-json\/wp\/v2\/media\/10626"}],"wp:attachment":[{"href":"https:\/\/garrenwood.com\/wp\/wp-json\/wp\/v2\/media?parent=10628"}],"wp:term":[{"taxonomy":"gw_hook_concept","embeddable":true,"href":"https:\/\/garrenwood.com\/wp\/wp-json\/wp\/v2\/gw_hook_concept?post=10628"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
