A Sierra pen in walnut, maple, cherry and padauk. There are 52 inlays in the pen. Not an original design, but one I found on vecteezy.com and redrew and adapted to fit a pen body.
I look at this and am reminded of the old Milton Bradley game, "Operation," where you had to carefully move parts with tweezers and not get zapped in the process. This is a magnificent blank.
(And be honest...how many times did you get zapped?)
