A small surface with a precise job
The tip and bevel are where the pick transfers the movement of the hand to the string. A clean edge helps that contact feel predictable.
Handedness
Some Wegen models can be prepared for right- or left-handed playing. That matters when the working edges are shaped for a particular direction of travel. Check the product page or ask Michel when a handed option is not listed.
Custom tips
Custom work can begin with a standard Wegen model and change the tip, bevel, thickness or dimensions. A clear description of your instrument and playing style is more useful than marketing language.
