STH Reels: A Legacy of Innovation and Varied Offerings in Fly Fishing

STH Reels, an Argentinean company, carved a unique niche in the fly fishing world from roughly the 1970s to the mid-2000s. While no longer in operation, STH left an indelible mark through its own branded reels and as a significant manufacturer for other prominent names in the industry. Known for innovative designs, a wide array of models, and a spectrum of quality that ranged from groundbreaking to entry-level, STH reels remain a point of discussion and collectibility among fly angling enthusiasts.

One of STH’s most recognized contributions was the popularization of the cassette fly reel system. This design, innovative for its time (particularly in the early 1990s), utilized interchangeable, inexpensive polycarbonate cassettes instead of traditional, more costly machined spools. This allowed anglers to easily and affordably switch between different fly lines in the field, a feature many found highly practical. The patent for this system reportedly lapsed around 2010, and the concept was subsequently adopted by other manufacturers. Models like the STH Cayuga and various IM series (including the IM-POP and MR Cassette) exemplified this system.  

Beyond the cassette system, STH was also known for its pioneering spirit in drag technology. The Sacconi turbine drag reel stands out as a particularly unique innovation. Named after the company’s founder, this system employed fluid dynamics, where the drag would start with minimal resistance and progressively increase as the spool’s RPMs rose during a fish’s run. The intention was to protect light tippets by providing a smooth, automatically adjusting drag. While perhaps not universally practical for all fishing scenarios, it showcased STH’s willingness to experiment with novel engineering concepts. Some models also incorporated more conventional disc drag systems, with the SLT series noted for its cork disc drag.  

STH’s manufacturing capabilities extended to producing reels for other well-known brands. It’s widely acknowledged that STH was the maker behind certain reel series for companies such as Orvis (including some saltwater CFO models and the Presentation EXR and SSS series), Cabela’s, LL Bean, and Cortland. Reels marked “Made in Argentina” are often indicative of STH’s handiwork. This behind-the-scenes manufacturing role highlights the company’s capacity for producing quality equipment that met the standards of established fly fishing outfitters.  

The range of STH reels was extensive, catering to various fishing applications and price points. Models like the Airweight (some of which were also Orvis-branded as the Presentation series) were known, while other series like the DDR Cassette also formed part of their lineup. They produced reels for various line weights, suitable for freshwater species like trout and bass, and some models were designed for saltwater applications.

However, the reputation of STH reels for quality and performance was somewhat varied depending on the specific model and era. Some reels, particularly those made for other brands or their higher-end offerings like the Gary Borger signature limited edition reels, were well-regarded and are considered valuable by collectors. These often featured good machining and reliable drag systems. On the other hand, some of the more budget-friendly models, especially certain cassette reels, were sometimes perceived as entry-level with occasional issues. Anglers reported concerns such as rough finishes on cast parts that could wear fly lines, inconsistent drag adjustments (going from too little to too much rapidly), lines occasionally pinching between the spool and cage, and in some instances, fragility of materials, particularly in cold conditions.

Despite the company ceasing operations, a legacy remains. For anglers who own STH reels, obtaining parts can still be possible. It has been reported that Bill Archuleta, a reel repair specialist, acquired STH’s remaining parts inventory, and other repair services may also stock components.

In conclusion, STH Reels played a notable role in the evolution of fly reel design during its decades of operation. Their innovations in cassette systems and drag technology, coupled with their extensive manufacturing for other brands, cemented their place in fly fishing history. While the quality across their vast range of models may have varied, STH reels are remembered for their ingenuity and the practical solutions they offered to anglers of their time. Today, they exist as functional pieces for some, collectible items for others, and a reminder of a distinctive chapter in fly fishing tackle development.
