This is a unique pen made from a genuine, once-fired .50 caliber machine gun shell casing. The pen is just over six inches long and the "bullet" end twists to extend or retract the writing tip. It takes Cross-style refills available at office supply stores. You don't need to worry about that right away, though, as the pen comes with a refill already in it. Sorry, I never thought to take a picture with the ink tip extended. To replace the refill, simply pull the pen apart right above the "bullet", unscrew the empty refill, screw the replacement in, and push the two halves back together. Overall length is between 5 1/4 inches to 6 inches, depending on the length of the "bullet"

The "bullet" ends all were hand-turned on a lathe by me and then polished.

This would be a great pen for a gun enthusiast or military member, or someone who just likes unique pens. Definitely a fun conversation piece!

I left the brass casing natural to show the patina that will build on the casing but a bit of brass polish and they become very bright brass colored.

Please convo us with which pen(s) you want.

Please note that unless otherwise mentioned, the pens listed below and showing in the pictures are the exact pens that are for sale. Also, as these are hand-crafted by me one at a time, unless otherwise stated, I only have the pens shown.

If you don't see what you want, convo me and I'll let you know if I can make it. I have made several sets of pens as groomsman's gifts, both with and without personalizing.

I just updated my pictures so the pens I have available are as follows:

Picture 1 - single pen picture - Bethlehem Olive - this pen is my number 10. All the pens have the same size and shape of the .50 caliber casing so all the other pictures show a close-up of the wood part - since that's the interesting part of the pen anyway. :-)

Picture 2 is left to right - red acrylic, red/white/blue acrylic (sold), multi-colored, blue swirl.

Picture 3 is left to right - Bocote (sold), Chechen, and Elm (sold).

Picture 4 is left to right - yellow acrylic (sold), purple acrylic, red/black acrylic, purple acrylic 2.

Picture 5 is left to right - two Tulipwood pens.

I have more 50 caliber pens with different woods and acrylics. Here is a link to the other pens I have.





I have more kits. If you would like something in particular that you don't see or that is marked sold, convo me and I will tell you whether or not I have the material to make exactly what you want.

Now available! I can personalize your pen, making it even more unique! See my other listing for lasering your message onto the brass of the pen casing!


Photography is NOT my strong point!
