Rikudou's stick is probably similar to the stick that belongs to the equipment of Japanese Buddhist monks.

There are different types of these sticks:

But, since I believe that Rikudou was something like a sohei (fighting monk) we may also say that his stick is Kanbo.

Or maybe, inspiration for Rikudou's stick is found in both Kanabo and the stick that Japanese Buddhist monks use.
Somewhere I found information that Kanabo is used in by oni ( Japanese demon) since they were reputedly extremely strong. But I'm not sure about that information.
The difference between Furido's stick and Rikudou's is obvious. While Furido's stick is very similar to Japanese Buddhist monk's stick Rikudou's stick is combination of that stick and Kanbo.
