A Question on Purple Heart

I used it once several years ago on a knife I gave my mom. It wasn’t stabilized and I wouldn’t worry at all about using it again. It seemed very stable in its natural state.

I've used non-stabilized purple heart several times with no issues.

 

Amaranth - AKA purple heat - is very stable. The color will change in time to a browner shade … or all brown. The intense color after sanding fades away pretty soon. Stabilizing slows this some, but it is just a fact of life with this wood.
It can also stain the hands during sanding, and a little if used wet … especially if wet with alcohol or other solvents. This isn't normally a big issue, as most knives are used dry.

Everyone seems to have a favorite way to finish it. I rarely use it on knives, but on turnings I apply a simple sanding sealer and then sand to a high grit. I then apply a friction polish.
On knives, a final coat of oil finish (any gun finish, Tru-oil, etc.) will make it smooth and shiny, but I don't like a built up finished.

If using an oil finish, rub it in - wipe the excess off after a few minutes - let dry a day or more - sand back to the wood with fine grit paper - repeat a couple times. This will fill the pores but not leave a coat of varnish on the surface. A good buffing with an old T-shirt will give it a nice glow.
