does translucent g-10 turn yellow after being used for a while? i love the look, but i definitely don't want sweat staining it yellow.
 
It mostly likely will if you don't keep it clean, but if you wipe it off everynow and then it should be good.
 
It all depends on the epoxy binder being used. The yellowing is due to UV degradation of the binder. Some of the resins have incredible radiation-stability properties. This is more true with the higher grades like G11, FR4 and PEEK.
 
Another thing I've noticed working with the jade-green G11 is that it displays something like metameric failure. It will look yellow in one instance and green the next. When laying two G11 chopsticks next to one another, the one closest to a window will look considerably more yellow than the other. Switch them around, and it's still the same.

It's still great stuff, though.

Noticed some of my fishing poles are turning translucent... Is this the same deal; UV degradation? Does it affect strength or is it just a cosmetic issue? I was rebuilding the guides on one of my poles when I noticed the adhesive was epoxy based... Does that mean I should keep my G10 handled knives away from acetone? Asking as that was what I used to soften the adhesive on the old guides.

Yes, it will affect strenghth as the binder degrades so does the strength. \

Don't know about casual exposure to acetone but repeated or prolonged exposure will lead to some sort of degradation.
 
UV degradation greatly affects strength. I've heard of tests of 1" Nylon webbing (4000lb MBS) breaking at body weight from a year of sun exposure. We have to be very careful using unknown-age webbing in our climbing anchors.

I haven't noticed a problem with casually wiping down G10 with acetone. That said, I wouldn't soak my scales in a vat of the stuff.
 
UV degradation is a surface phenomenon. Webbing fails because it is composed of individual filaments that all have surfaces that can absorb the UV. A chunk of epoxy on a knife handle will not really lose much strength unless you leave it outside where it gets direct sunlight for a couple of years.
 
I've never heard of translucent G-10, does anyone have a pic of what it looks like?
 
Not my pic...

I don't know about all of you but I love the translucent G10. If it yellows with age
then so be it that's my opinion. Like a carbon steel, or an old piece of Oak you
know it probably won't ruin it and look pretty fine with age and a little use.

Thanks for the pic!

I does look cool but, isn't exactly see through:p
 
Check out all the Spyderco Leafstorm threads. I've installed a 3mmx23mm trit vial on the inside of my Leafstorm which is able to glow through the translucent G10.
