Benefit #9: It lets you go really fast.
With practice, the one-handed turn becomes an automatic movement you make with your needling hand, allowing your palpating hand the luxury of locating the point, determining the direction and type of vector you want to treat, and understand through palpation which needle technique will have the best results at the point. The movements of the needling and palpating hand occur simultaneously, so that as you have finished your palpation of the point, the needle is loaded and ready to insert.
Seirin needles work very well with the one-handed turn, because you can free them from their tubes by twisting the handle with your needling hand, and then use the turn to load them into the tube you are already holding. If you have a package of needles open in front of you, your palpating hand is free to roam over the entire treatment area to find the live points without having to stop and take part in readying the needle. Treatment of multiple points in an area proceeds very quickly in this way.
