Ok, this may be a silly question, but is there anyone that offers any type of high performance blade coating? I know this is a silly question to some, but I think it would be kind of cool to have a knife or two with a custom coating/paint job. I love the damascus offerings and enjoy the mirror polishes, but being able to have a blade with a camo finish, or diamond plate, whatever you can come up with would be kinda cool. Guess I like things flashy sometimes. Any thoughts or am I totally out in left field all alone on this one?

Kuhn Rikon makes knives in tons of colors and patterns, and they are razors out the of the box. Kinda joking about the quality. They are pretty low quality knives, but they some how make them in every color and pattern, so it can be done. Maybe look into electrostatic painting. I know that's how people paint stainless steel appliances.

Well you have a couple of options, the first being hydrodip painting. Basically a stencil is placed over a water based solution and the product is dropped over the floating stencil which glues itself to the outside. Very tough finish but can flake if flexed (similar to spraypaint) However you can get any pattern you can draw.

The next is anodizing, where an electrical current is passed through a metallic based paint and then is attracted to the negatively charged knife. This is a very even coating but is expensive. You have the option of doing splash and acid washes but no real distinct pictures.

One thing you might be interested in is anodizing and then laser engraving. This basically removes and bleaches a thin layer of anodized paint which can be done in a specific pattern.

This would be hydro dipped: http://cdn2.cheaperthandirt.com/blog/wp ... ger_10.jpg

I had thought about the hydro printing, just not sure how it would effect the performance of a high end blade.

In terms of it being non-stick, it would be similar to a kurouchi finish I think. You wouldn't be able to have it over the edge for obvious reasons.

This is why people pay a lot of money for crazy looking Damascus like in the bloodroot blades.

I might be concerned about the composition of the coating. I know powder coats and the like are extremely durable, but with things like chemical off-gassing and leaching I would be unlikely to coat a knife in a kitchen setting. But then I tend to worry about such things :)

Definitely a possibility, but once cured, most of those coatings are inert unless heated. Appreciate the thoughts on this. Was a hair brained idea this morning.

I don't think it is hair brained at all. I think the look of some of the coated knives is pretty cool...when it's not too kitschy. Mel has talked in other threads about his Teflon coated pettys and says they work very well.

I just tend to err on this tree-huggy side of that street :)

im pretty sure the teflon coating is not for aesthetics and mainly for non stick qualities.

Sure, but all coatings have a functional purpose, even if they are not applied for that reason. Non-stick, corrosion resistance, increased durability, decreased sticksion (sticktion, sp? :)). I understand that in this case, the likely reason is aesthetic. For me though, to consider it, I would need to see specific functional advantages.
