Hi Paul. The Clutchlocks sold quite well when we had them. G.Sakai decided to disco them. We never heard the reason, but my guess was that they were cost prohibitive to make and this was discovered during the mfg process.
Because we had commitments and because G.Sakai is an honorable company, they honored our commitments and made a few extras for us.
They are not back in production and what we have is very limited. When they're gone, they're gone.
