I've read on another site that the "Colors are created by the application of electric currents in different intensities and duration to the titanium oxide."

Is there any truth to this? If so, I would imagine that each knife handle would be unique since one would not be able to get the electricity to flow exactly the same each time it was applied. I've just recently become interested in the Leek and have yet to see a rainbow finish in person, musch less two side by side to compare them.
 
I would think the current being controlled by a computer program would keep things consistent.

I suppose the computer could control the amount of electricity flowing into the metal, wattage and amperage. But how do you control the route that the electricity takes? That would be like trying to control the path of a lightning strike. Sure you could put a lightning rod on top of your house, but you can't control the route that it takes to reach the rod.

To consider that each finish would be a custom job makes the idea of owning one even more appealing.
 
I don't believe electricity is actually used to "charge the parts" in their process.
More like a PVD process. Vacuum chamber, titanium vapor. Reactive ion coating makes a very uniform coating.
I'm not sure why the coloration happens the way it does.

I will contact a member here that works for the coating company.

These are the best photos I've been able to make to show what it looks like without "seeing" it for yourself in person.

I have the leek and chive in VIB, I really like them. They are pretty and I like pretty. I think every coating varies slightly just as anything does but all are "pretty" consistent.
