Koenig Knives PQD-G1 Pen - Titanium / Bronze Anodized Tip & Body / Grey DLC Clip and Pen Cap

The PQD is just the kind of pen you'd expect from Bill Koenig. Its simple click mechanism smoothly pushes the plunger through a ring of bearings, locking it securely into place. To retract, simply push upward on the pocket clip, or pop it back into your pocket, purse, pouch, or bag, and the clipping action automatically retracts the nib. This is an amazing design from one of the best in the business!
