For this hack, we started with a gunmetal 0.5mm Spoke Model 4 Supergroove pencil with Titanium grip. The grip was torched to a Bronze color then brushed to to a semi-shiny appearance on the outer grip, leaving a bronze look in the groove. It's a cool two-tone look.

The Super Groove grip is a large 0.42"/10.5mm diameter cylindrical Titanium grip.  This is not a smooth feeling grip, the large deep grooves give the grip a definite edgy feel.

Pencil Only. Accessories now available separately via add-on.

Powered by the classic Pentel P20# mechanical pencil mechanism, the pencil features a 4mm fixed sleeve tip and eraser under the back cap. The mechanism is easily replaceable in the event of accidental damage.
