If you search eBay for 'stainless steel tactical pen' or 'titanium tactical pen', you will find a large number of listings for inexpensive pens machine turned from solid round metal stock in China. I have several of them, in stainless, titanium or brass, albeit I had to search a bit to find plain pens without all the tactical sharp attachments or add-ons that get them confiscated from me at the courthouse or the airport. These are shipped directly via China, and I have discovered that they generally take a couple of weeks to get from the PRC to me in the Seattle area. It is much cheaper to buy them directly from China as opposed to the same pen on Amazon that has been marked up 400%.
