I am an imprisoned writing instrument addict.
I wanted to share my version of combining a nice stainless steel pen barrel with the fantastic space pen refill ink cartridge.
Even-though this is not my invention - it is a new idea to me, which I had to create.
The everyday carry world aka EDC - which I am also addicted to – reveal the ideas of maximizing usefulness of what we carry.
The Tactical Space Pen is an item that fits my bill for a EDC pen.
The marbles pictured are from my childhood - another passion.

Step 1: Items Needed and Tools
Items to combine into one
Zebra F-701 Ball point pen, fine point 0.7mm
Heavy-duty stainless steel barrel
Easy to hold knurled grip
Retractable cartridge – not going to be used
Fisher space pen cartridge – Medium point black ink
It can write in all conditions
Curved dental pick - other sharp objects could be used
Step 2: Open Barrel and Remove Internal Items
Open Barrel and remove internal items
I twisted (unthreaded) the tip of the barrel.
I took out the retractable cartridge (put it in the drawer for possible future use)
I saved the spring to reuse for this project.
Using the dental pick, I pulled the plastic plug out of the tip.
Please note: It does not take a great deal of force to pull the plastic plug out. I suggest that you reach as far down in to the tip with the pick.
Also note: I believe other styles of picks could work. I used what I had available.
Step 3: Replace Components
Using the existing spring, I reversed the dis-assembly process - but using the space pen ink cartridge.
Side note: the space pen has a plastic spacer in the packaging. This plastic spacer is not needed for this application.
Step 4: Finished Tactical Space Pen
This was a great little project.
I have several requests for additional pens.
