We have started shipping Hapstone V6 Revision 2 this week to both US and international customers. All pre-orders will be shipped before May 1st. Unfortunately there is some delay with diamond bundles. Customers who make pre-order of V6 with diamond set will receive 2 parcels: the sharpener with basic stones and the diamond bundle 1 week later.
