You are looking at one of my deer hunter pens.  This bolt action pen is in antique pewter, made with a red, silver, and black acrylic.  The pen is sized to a replica 30 caliber casing and bullet. 

Some features of the pen include the tip is shaped like a 30 caliber bullet, the metal part next to the tip has 2 deer heads cut in the metal.  Above the  body of the pen, the upper metal part is shaped like a 30 caliber casing, complete with ejection rings around the casing.  The clip is shaped like a open sight, with a buck deer head on the clip.  The clicker mechanism is shaped like a bolt action of a rifle.  The end of the "casing" has a replica primer in it.

The point is extended by pushing the bolt toward the tip and in to the notch and to retract just reverse that action.  The pen uses a Parker style refill.  When a refill is needed you just unscrew the tip and replace it just make sure you put the spring back on the new refill then just screw the tip back on the pen. You should be able to find these refills at an office supply store near you.

The tip of the pen is a rose/copper color.  The acrylic was sanded to 6000 grit, then finished with several layers of acrylic polish, buffing it to a medium shine.

The pen is about 5.25 inches long retracted.
