Hi Friends, i have only just registered to Kendo-world yesterday and i am really interested in the world of swords....currently i own a Tai Chi collapsible sword and i was hoping you guys can teach me about maintenance of a sword. i was told that i should use Wd-40 to oild my sword. Does anyone else have any good advise or tips to help me out?
One more thing, when i want to retractr my swrod blade back to it handle is there a specific method? cuz it kinda hurts when i push the blade into the handle with my hand.; Well that it for now.

P/S: Anyone out there own a collapsible sword i hope that we can share a great many thinngs about the sword and all.
