SO I ordered these as i love the look they give when i daily carry my sabers. I discovered however that adding one to the top of the tsuba and then sliding the retention screw on looks incredible! What a fun piece to customize the look of the saber. On another note adding 2 of them together to protect the threads when i fight one handed is great. i lowers the weight slightly and removes the protrusion of the tsuba so i do not have to worry as much about accidentally hitting someone with the tsuba itself. Definitely a must have if you own the threaded emitter saber line.
