Mezz Wavy joint system has a longer shoulder to help locate the pin into the center of the hole for more accurate installation and the unique double threads shape of the wavy pin will join solidly into the wood of the shaft precisely.
This Miki’s original metal-to-wood joint construction (the flat-faced, wood to wood joint) gives you the solid Mezz feel while delivering the power of the stroke and transmitting feedback to the hand firmly.
If you like the flat-faced wood-to-wood joint, precise alignment and an extremely solid feel, no other metal-to-wood joints come close to competing with the Mezz Wavy joint system.
