Cap,

The reason that this configuration can no longer be ordered is because as of 2011, it will have six chargeable options. The #6 Grind on a #4-6", regardless of whether the blade is carbon steel or stainless, is now a chargeable option ($10). It was a non-chargeable option up until now.

Interestingly, the #6 Grind is still a non-chargeable for the #7-4.5" and #7-5" knives.
