The Barreled Acupuncture Insertion Tube
This is also one of the oversized Acupuncture tubes with a 4.6mm diameter and 70mm length. It has the diameter reduced throughout the center section to about 4.1mm so that only the ends that contact the patients skin and the practitioners oshide maintain the full diameter. This was modeled after some steel tubes that one of my clients particularly liked. His tubes had more of a angular/mechanical and "trumpeted" appearance, with a greater reduction in the midsection. I wanted to maintain a little more softness and roundness to this subtle accent. I also chose to call this effect barreling. This is a term used in archery to describe an arrow that has been tapered and reduced in certain sections to improve its aerodynamics, and penetration. I did not think I would like this shape, but after handling it, I have quite come to like it. The indentation where the diameter swells fits perfectly to the thumb and middle finger when holding the tube or performing one handed reloading. The relative extra mass at the ends makes the tube want to spin in the hand during reload very smoothly. This is very fun and functional. I still have a personal preference for smaller diameter tubes as long as they have ample mass. Fortunately, this feature could be built into my normal diameter tubes as well for the best of both worlds.
