Platinum Series

A batch of new Nubatama synthetic waterstones, in limited quantity. Once these are gone, they're gone.

Nubatama Platinum Series waterstones deliver the highest abrasive density in the lineup, built to cut through hard, high-alloy steels—D2, SG2, ZDP-189—that overwhelm standard waterstones. Rather than a separate stone family, Platinum is a high-density formulation found within both the Ume and Bamboo lines, cutting faster and dishing more slowly than their standard counterparts. Ken Schwartz on Platinum's place in the lineup →

This Nubatama collection comes from the acquisition connected to Ken Schwartz's collection (see Provenance).
