Most of the Rosewoods other than Cocobolo are probably better for this purpose. Less brittle on the edges. Still, I think they too are too brittle. If I wanted a good hard wood with self lubricating properties, I would probably pick Verawood, a Lignum Vitae relative. Else I would use Ipe.
But...I would simply use hard Maple. Easily replaceable and inexpensive. But if the qualities of the exotics are what you want, even Bubinga would work very well in addition to the above list.
Take care, Mike
