Product overview Precision replacement springs made from piano wire for reliable elasticity and longterm use. Net weight: approximately 4G per spring set, adding minimal weight to the device. Package contents: 3 PCS springs. Key benefits Restores or improves mechanism feel by providing consistent tension and smooth action. Lightweight design avoids adding noticeable weight while maintaining performance. Durable piano wire construction minimizes deformation over repeated use, maintaining function over time. Important attributes Material: piano wire, chosen for elasticity and fatigue resistance. Function: replacement springs for folding or locking mechanisms requiring consistent spring tension. Compatibility: fits Microtech Combat Troodon series models. Weight: net weight of the set is only 4G, keeping the overall balance unchanged. Practical use scenarios Replacement during routine maintenance to restore original action on a compatible folding knife. Upgrading worn or weakened springs to regain crisp deployment and consistent locking. Carrying a spare set for field repairs when a spring shows signs of fatigue. Installation notes and tips Inspect the existing spring and mechanism for wear before installation. springs one at a time and verify correct seating and orientation in the mechanism. If unsure about installation, consult a qualified technician or refer to manufacturer maintenance guidance.
