what's that red/white stuff you put you knife in to ?
how do you treat the wood under the ring ?
and ofcorse is there anyway of removing that ring without buying those special pliers ? i have tried to remove that ring with 3 different pliers and the ring is still there...

and uhm.. some guy told me that the ring is made of nikkel, is it ? or is that only on the staninless ones ?
