I've purchased a new knife from Joker Knives.
Joker Knives doesn't stabilize handle scales, although they are very well sanded.
My knife was supposed to be brown canvas micarta.
It's VERY light brown. Barely brown.

Do I need to stabilize the Micarta or treat it?

Wicked Wax will darken your micarta and provide a moisture barrier; I put that shit on everything, carbon steel, leather, wood, micarta, ect... :cool:
 
Oil or wax, like they said above. Freshly sanded micarta is lighter in color than oiled, waxed, or well used micarta.

This was the information I needed. Will 100% Tung Oil work well?
What type of oil would get the best results? Will the handle feel oily
if I used Mineral Oil?

I am still working through a tin of "axe wax". I put it on micarta that I leave rough enough to be fuzzy, 120 or 220 grit, usually.

I personally wouldn't want to use something that's going to dry and "seal" the surface of the micarta like tung or Danish oil. I like the way micarta acts when it gets wet and I like being able to scrub it with dish soap and a brush to clean it up when it gets gross, like dropped in used oil.

I’ve used mineral oil to darken micarta. It’s impregnated with fiberglass, so I’m not sure how much stabilizing oil does. Less is more. Just a few drops should do ya. Personally, I prefer to let the natural oils on your hand to darken it now.
 
That light tan micarta can be dyed to a lot of good colors: any shade of brown, rosewood, yellow highlights. I use an alcohol based dye (not stain) and test on an inconspicuous corner. Then hit it with a couple of coats of fresh shellac to lend a little water- and stain resistance. Much quicker than the evaporating oil finishes.

And where would I get such dye?

Micarta does not need to be treated. It consists of layers of cloth in resin, typically phenolic or epoxy. It does not degrade mechanically, but can change color over time.

Micarta can darken with use. The exposed layers of cloth can absorb skin oils. So you CAN seal it or change the color, but it's not actually necessary aside from a cosmetic viewpoint.

I use the bright, easy to use dye from Stewart MacDonald Guitar Shop Supply, but any higher-end woodworking site should have something useful, maybe a little cheaper. Some of the colors can be spectacular on lighter colored work pieces. Stew Mac also has shellac flakes, which are good to keep around the shop.

I used to be an equipment mechanic. A law of that world is that if something can fall in your drain pan, it will.

Just an example of how Micarta can change -
This Charles May OSK-1 has “natural” Micarta with 2 blue lines. The lighter color was the way it looked when it was delivered to me. The darker color is about a year later.

This is a topic I've been meaning to ask about.

I've been playing with vintage micarta lately and it sucks to shape a handle and have the 'bark"/patina on part and the lighter inside colors both visible and then the material darkens to match the dark color again.

Is there any way to keep the micarta from darkening?
