The Saxworks is a CNC copy of Sanborn's favorite D8 Dukoff. It is somewhat different than a standard production Dukoff: a good facing, the chamber has no lump or wart at the end and the tip rail is nicely recessed from the baffle.
Sanborn endorsed these pieces when they were produced, though it is my understanding (and most everybody else's I've talked to) that he does not play one currently. Saxworks pieces play with a lot of stability and are not quite as piercing/cutting as the familiar/typical Dukoff sound that people associate with Sanborn. His sound is also heavily processed. His skill is for real!
