FUBUKI™ continues to be our proving ground for disruptive, category changing ideas. The FUBUKI™ V-Series features Power "Ninja" Core (P.N.C.) Stainless Steel Mesh Technology, in addition to our newest innovation – Impact Stabilization Technology (I.S.T.). I.S.T. utilizes variable material stiffness in the lower third of the shaft to minimize unwanted “lag” and “rebound”, to deliver more control and efficient power transfer through impact.
