Koah 19/64 (7.5mm) Hawaiian Shaft

All KOAH Shafts a constructed from the highest grade centerless ground 17-4 stainless steel which is machined and heat-treated in-house. Since our steel is centerless ground that means the selected size of the raw shaft material is actually ground down from a larger diameter. This means that the final diameter of the shaft is extremely accurate and larger diameter imperfections and steel stress points have been removed.
