Removing rust

[karatekaBR86]

I have noticed rust stains on my Shureido Sai. Anything I can use to remove them?

In my instructors dojo in okinawa they have small sections of bamboo cut at a joint so as to make a cup about three inches tall,they then stuff a rag in it to a stuffed overful condition they then pour in some oil(light clean mineral or vegetable oil).They use this to oil the sai after each workout,alongside the oil cups they keep a stack of rags for wiping the sai down before working out.Myself I just wipe my Shureido sai with engine oil about once every couple of months,I have found this to be very effective in rust inhibiting,works on my tekko also.Be very careful to thuroughly wipe the oil off before starting your workout to prevent throwing the sai accidently.Also try not to oil the handle wrap it tends to absorb the oil and is difficult to clean.
