Designed for players who expect stable tuning and long-lasting hardware, this set features six precision-machined titanium blocks.

Premium Titanium Construction for Advanced Durability

What distinguishes these insert blocks is their use of KTS titanium—well-known for its exceptional strength-to-weight ratio and resistance to wear. Over time, titanium blocks offer more consistent locking action thanks to their ability to resist both corrosion and deformation, unlike conventional steel or alloy parts.
