Key features

Our own CB-6S: the Ø20 mm blade made for Sumitomo's auto-rotating cleavers — FC-6RS, FC-6R+, FC-7R and FC-8R
Tungsten steel edge rated for 78,000 cleaves — the long-life option for the R-series blade system
360° auto-rotating pattern: 24 cutting positions worked through in turn, so the edge wears evenly around the whole disc
Field-replaceable by the user, as the cleavers were designed for — a minutes-long swap, no service center
The standard spare for every R-series case: one fitted, one in reserve is how working fleets run
