Spray paint on a knife blade?

[51Jake51]

I really don’t care for shiny knives and I want to put some sort of coating on my blade. I’ve seen a lot of things that work but I was curious about spray paint. Would spray painting my blade be a bad thing? And how would it wear?

Your best best would be acid etching, it looks good, but you will have to sharpen it again, check out youtube for vids

I’d imagine it would wear pretty quickly/easily. If it were me I’d save up and get the blade cerakoted (sp) or something similar. The only spray paint I’ve ever seen on blades starts wearing off almost immediately upon any type of use.

Spray paint would probably not look good, or stay on your blade during even light use. You could look into Cerakote or similar products used for coating firearms. They're ceramic based and need to be baked on after you spray them on, but they're much more durable

Make sure you use green spray paint. Makes it cut better.

Never would spray paint a blade. It would look horrible in a short time from any use. Like said in other posts there are other options.

Maybe a satin or flat clear spray varnish?

A non-stainless you can force patina or just let it develop naturally . But nothing good DIY for stainless .

I never like even most commercial coatings until DLC . Most looked like with any use .

I'd just make sure to get a decent DLC blade , like from Cold Steel , on your next purchase .

Not spray paint. Poor adhesion, easily damaged.

If you don't want stainless steel "shiny", you could use some fine sandpaper to roughen the surface.
If you actually want stainless steel dark, then I would recommend something like this:

Paint won't wear well on a knife blade - it'll quickly be scratched or scraped off with use. And paint can make a clogged mess of a sharpening stone - anyone who's sharpened a painted yard tool or lawnmower blade could likely attest to that.

Sometimes, just a coarser sanding of a brightly-polished stainless blade can be enough to knock the glare down, by diffusing the reflected light. Something in the 150-320 grit range could do that.

If it’s carbon steel. Force or let a patina develop, embrace the patina.

If its stainless steel . You can scuff it up so it isn’t like a mirror. But it will never be anything but bright.

You need to know what you want before you buy.

Spray paint will look great…….for about 12 seconds.
