## **Introduction**
For fly fishing enthusiasts, the **Pflueger Supreme 578** reel is a classic piece of gear that has stood the test of time. While newer models have entered the market, many anglers still prefer the **New Old Stock (NOS) Pflueger Supreme 578** for its durability, smooth drag system, and vintage appeal. One of the most critical components of this reel is the **drag knob**, which plays a vital role in controlling line tension during a fight with a fish.
