Show me purpleheart wood years later... what´s the best way to protect color?

Perhaps these two might be of assistance.



The real take home lesson for many beautiful woods is that the color change is inevitable. You may be able to slow it down by using many coats of varnish with UV inhibitor, but that only delays color change, it does not prevent it. I know that is not the answer that you want, but that is reality.
really helpful. thank you. it pays to do your homework prior to starting a project. thanks for your help.
 
really beautiful workmanship. how old are they? I found a website that states purpleheart keeps its color about 10-15 yrs.
Thank you!
the wood itself I got around 2012 or so. I made the knives 2 years ago.

To the Original Poster here, you did ask a pretty darn tough and hypothetical question... and your snapping at people and passive aggressive responses ("I hope this clarifies what it means to be helpful" for instance) are not going to make people want to help you with this...
You will get more flies with honey than vinegar as the saying goes.

As to what you can do for these hypothetical knives and grandkids, I have no clue. I have seen purpleheart used in some bows, and it is pretty but I dont know what kind of finish you would use on it. Try calling up a maker of traditional bows, like Bear Archery or Black Widow bows, and ask them what they use with Purpleheart. They would be the experts to talk to. Truthfully, any natural material will age and change, and that is part of the beauty of them. Good luck, and I hope your knives and your future progeny turn out wonderful! :thumbsup::)

nothing hypothetical about my questions, only thing hypothetical is the brains of the people who answer in this forum without knowing.
 
Check out GluBoost. It's a very slow drying CA glue. Wood turners use it to preserve color on high-end pens (and other turned objects). Guitar builders and repairman use it, too.
I've used it, it's a good product. I'd advise wearing disposable gloves when using.
