Designed in collaboration with Pat Ehlers, these tools ensure consistent compression and clean, professional-looking bullet heads every time. Machined from high-quality materials with an ergonomic design, the Nullethead Tool Set provides comfort, precision, and long-lasting durability for fly tiers at all skill levels.
