You can use various thin metal to get a ping sound, take the inital attack off it, add a swoosh from a brush or broom or whatever to the start, and it gives you a swooshing sound with a inggggg to suggest it's a very sharp sword.
It's a basic way of thinking about it, obviously it would take more than just that to make it sound convincing and good, but you gotta start at some point, and from there you build it up to your own needs!
Recording hoses and other items like wooden baskets being swung/swooshed around is a useful idea too to get heavier, hollow sounds, it helps as part of the layering process to create a different size of sword, usually can be useful for heavier swords.
Hope that was of some use! If not, I apologise for wasting your time
