Great product, I got the 24'. I was expecting to 'get what I paid for', and hoped for the best. Was beyond my expectations. Like everyone says, the chain does rattle when inside, stealth this is not. The end the chain goes in is a small hole, on it is a disk that prevents the swivel from coming out. I tried to catch the swivel in the lip of the hole, but it pops into place every time, so you can expect the chain length to be the same every time. It would be difficult, at best to put anything down inside to quite it, if you did get it in there, it probably won't come back out. The chuck itself is well constructed, if you held a mag lite(w/o batteries) it almost feels the same. These are fast chucks and lighter than wood, but not as fast as speed chucks built for the purpose. The ends are knurled for grip. Make sure to tighten well before using in stick form or it will loosen up after a couple of swings and could possibly damage the threads. It takes about 3 or 4 twist to open, one if you roll wrap your arms around it. It goes together very much like a pool stick. Lastly, would like say karatedepot.com delivered as I expected.   Permalink
