5* Spur

I currently use the Arc Razor as my all-round weapon, but looking ahead it seems a little daunting not being able to follow the alchemy path up to 5*.
For those who don't know, the Spur family starts at 2* (Spur) and finishes at 4* (Winmillion).
My question is, will Three Rings create the 5* version, or will it be stopped at 4?
As for those who think that I should screw the Spur family and move over to the Cutter one - I don't like it. I find it far too fast/weak for me, plus there are quite a few downsides that I would find hard to deal with. What's wrong with disliking a set?
Oh, and I find Calibur/Troika too slow. Well, aren't I picky!
So, any answers?

There is a 5* spur weapon; however, you will most likely never see it. It has been in gam a long time and is owned by a person on the OOO team it is a unique item and this means they will (most likely) never release it to the general public.
In answer to your question give it up. Move on.

Such a weapon does not exist in spiral spy.
Currently there is no 5*. But there are threads in both Arsenal and Suggestions to make a 5* spur. Look them up.
