I have SS, Brass, Delrin & Wood. All of mine are one piece. I tried the Brass but it's not my favorite. I use the SS at matches and at home, have "T" handle on one, ball on a couple, both are fine. I cut the Delrin to length of Rifle to use during Woodswalk matches,(Leaving the wooden Rod at home) lite weight and no worries about breaking and splintering with possibly getting stabbed in the wrist or hand. The Wooden ones are built with Brass tips from TOW with worm on one end, 10-32 for cleaning jag or other tools as needed on the other end and I will leave them in the rifle for more period correct times such as Rondy and hunting. For me, its about Safety First, and having FUN. Accidents happen and that takes most of the FUN away. Just my TCW. Thanks for several good tips on here!
