Here are some pics of the new hybrid blasted / tumble polished finish. Its the finish I apply to all my personal pens. Has more of the durability of a blasted finish but the smoothness of a stonewashed finish. Thankyou all who have submitted name suggestions.
I enjoy that the finish provides a very uniform surface look and slightly polishes the hard edges. The crisp lines get a bit of a shine to them while feeling glass smooth in the hand.
Process is delicate enough that all the milling lines for the isogrip pens remain visible. A fantastic finish for this particular Isogrip pen which has a bazillion edges to work with.
Here you can just see a few fine lines of polish on the edges of the cap chamfer. An all around great finish for pens that are intended to be used.
