Annodized Titanium - Is it Durable?

Have you ever owned an anodized titanium razor?  I am wondering about durability and water spotting.  I live in an area with hard water.  Thinking about a darker blue color.

I’ve never owned an anodized titanium razor but from my experience with many other anodized titanium tools, it does fade with use.

No other opinions?

I had a sky blue anodized titanium razor handle from Triad, and its color gradually faded, although it did not seem to water-spot.

The type of treatment used to anodize Titanium (thermal or electrolysis) is not permanent as it doesn't fair well against friction or scratches however it does well against the elements. In the end all it does is add an oxidation layer on the metal so think of the coloring as an optical illusion. The wear and tear will depend on your handling and exposure. One could preserve or protect the anodizing with some clear nail polish but I doubt it's something you wanna do on your Ti razor.
