Sword Components - availabillity ??

[katana]

Could anyone recommend or know of traders that may have sword parts for sale, or actually specialise in this field. I have several regulation swords that require a few parts ....lost due to damage/or otherwise. I appreciate that some believe a sword should be left 'as is' ....I agree if the sword has 'historic provenance' ....but I feel some swords deserve to be made 'whole' again. I would rather fit the genuine article...than have parts made. I personally feel that this is 'acceptable'....after all swords would be often repaired / had replacement parts during their working life.

I wondered what others thought about this ....and thoughts on sourcing parts.

Kind Regards David
