Chef, I had smooth bells previously, but the guys running Sovereign Protectors have determined that the bells have a ridge. In fact, according to them no future Shadow Guards will be approved without the ridge. It would help of course if they ever updated the CRL as they have been promising for quite some time.
Crazas, my pike is just an Ultrasaber. I have not been successful in sourcing an accurate pike yet. There are two fellows on Shapeways that offer 3D printed parts to make your own, but it is super costly and has yet to be done in the real world. There is also a fellow in Germany I believe who machines one without electronics for like $500 or so shipped, but that is more than I want to spend as the base for my pike.
