You guys are funny!
The reason for it being the 17th anniversary is actually pretty simple (and a little embarrassing). It was supposed to be the 15th anniversary model, but our engineers decided they wanted to redesign everything and spent 2 more years in the lab! Both the DK-4001 and the 17th anniversary limited edition model were developed around the same time, so it was renamed the 17th anniversary model. It seems a little strange, but we wanted to make sure we honor our supporters with a very special product and give them something that was the best we could make!
Because of the silver finish, it is even harder to make than the DK-4001! We are still waiting for the factory to finish the latest batch of shells before we can inspect, assemble, QC, and ship.
But we are discussing making a new dynamic flagship based on this model, so even if we can't let everyone experience the 17th anniversary limited edition model, the next model will be mass produced!
