Is My Stick Bent or Broken?

Distinguishing between a bent stick shaft — a permanent deformation that alters the stick's geometry — and a broken stick with visible structural failure is sometimes straightforward and sometimes surprisingly difficult. Knowing which situation you're dealing with determines the right response.

What You Need to Know

A bent shaft is a permanent deformation of the composite structure without visible failure. It typically results from sustained loading at elevated temperatures — storage in a hot vehicle, leaning against a warm surface, or being trapped under weight. The shaft appears visually straight from most angles but reveals a subtle curve when sighted end-on. Bent shafts alter the stick's lie geometry subtly and can affect how the blade sits on the ice in the player's natural skating posture. They cannot be straightened — the thermoplastic components that deformed will not return to their original geometry under normal conditions.

A broken shaft shows structural failure that may be visible as a crack, a flat spot in cross-section, a delamination of the outer carbon layers, or a complete separation. Intermediate failure states — a ghost crack where the resin matrix has failed internally but no external damage is visible — are detected through physical flex testing: a compromised shaft produces a soft spot or creak under hand loading that a healthy shaft doesn't exhibit. Any shaft showing visible structural failure should be removed from game use immediately. Any shaft that feels soft or produces unusual sound under hand flex testing should be treated as failed and retired from game use regardless of visual appearance.

Key Takeaways:

• Bent shafts result from sustained loading at elevated temperatures — they cannot be straightened and alter blade lie geometry
• A bent shaft reveals its deformation when sighted end-on even when it appears straight from most other angles
• Broken shafts show visible structural failure — cracks, delaminations, cross-section distortion, or complete separation
• Ghost cracks are detected through flex testing — a soft spot or creak under hand loading indicates internal failure

Bent and broken are both reasons to retire a shaft from game use — the difference is whether the issue is geometric distortion or structural failure, and physical testing is the most reliable diagnostic for either.
