Spare pick for new Quark, Nomic and Ergo. The same tooth configuration as the Astro pick first seen on the Nomic but with a small section machined out to allow fitting of the new adze and hammer accessories. Tough for torquing and hooking up long mixed pitches and sinking in turf.
If you want to use your tools without the hammer or adze then re-fit the spacer as per the original set up (Nomic and Ergo). For Quark users the spacer comes in the little bag with the Allen keys.
