The Park Tool BSH-4 Bladed Spoke Holder is a specialized workshop tool that makes wheel truing and spoke service easier and more precise by securely holding spokes in place while you tighten or loosen nipples. When adjusting tension on spokes, they can sometimes twist rather than turn the nipple — especially on bladed or aero spokes. The BSH-4 prevents that by gripping the spoke blade safely, giving you confident control and preventing unwanted twist that can lead to uneven tension or spoke damage.

Designed for repeated use in home workshops or professional service bays, the BSH-4 features a durable blade-grip design that fits a range of spoke shapes and sizes. Its ergonomic handle provides leverage and comfort during extended truing sessions, while the secure grip reduces the risk of slippage or knuckle bangs. Whether you’re building wheels from scratch or fine-tuning tension after transport or impact, this tool helps keep your wheels true and tensioned correctly.
