I made it down to Golden, CO last month to see the Aqua Salts in person. Sal mentioned that they should be available in late September.
They are every bit of what one would expect from Spyderco, plus some. your description of "brilliant" almost sums up the Aqua Salt knives. Can't wait to get my hands on 'em.
Only problem I can see with them is that both my outdoor knives and my kitchen knives will be neglected shortly after their arrival.
