@Sandy: Yes, there appears to be no perceptible wear in SS frets, at least going by what I have read, therefore the increased ease of stringbending is likely to be much longer lasting than it would be with newly polished conventional frets. The other advantage (as I perceive it) is that the SS frets are way taller than the conventional frets installed on your normal factory dreadnought, and I feel there are benefits to be gained by using taller frets (although not everybody would want them on their guitar, granted.)

@Escapee : I have some experience of stainless steel, I have installed SS sheets as wall cladding in a commercial kitchen so I know to use cobalt drills, and also thin angle grinder blades, but that's about it. The received wisdom as far as guitars go is to make sure that the fingerboard is perfect before you install the frets, so that they don't need levelling and crowning thereafter. Whether that is doable, I will find out. Obviously the ends still have to be filed, but with care the surplus metal could be kept to a bare minimum. I am under no illusions, it will be a difficult and time-consuming job.
