G10 & a black light

Ok, this is a little weird. Looking at a few folders under the fluorescent black light in my room, I've noticed that G10 scales occasionally appear to be a bright lime green color. The military, Al Mar SERE 2K, and one of the new Spydie/BobTs do this. I figured it was just something to do with an ingredient of the G10. My Benchmade 710 doesn't do it though. It feels weird anyway, so it might be a different brand or composition of G10.
Ok, here's an interesting part-

my gunting stays black on the clip side and glows green on the dimpled side. Weird, eh? My buddy's gunting stays black under the blacklight. Any ideas as to what's going on? Sal- did you guys run out of one type of G10 in the middle of making my gunting?

Oh yeah BTW the Gunting is a great knife to play with, even if you'll probably never cut something with it. Kinetic openings on pizza boxes, edge of the counter.....

Hmmmm...I just checked my military in the black light and didn't see it glowing...

Maybe you've gotten something on your knife that glows like detergent or something...
 
I believe G-10 is one of the woven composites; because of this, when ground in a certain direction the ends of the composite mesh are exposed, fluorescing under the black light. This is completely out of my a**, but it makes sense to me.
 
Wow, I just tried this with my Gunting. The clip side glows blue but the dimple side stays black. Very weird. I'll upload pics in a couple of minutes. I'd be interested to know the answer to this question and why one slab is different than the other.

Looks like I've got the CRIMPT but that's the same knife!

Also my friend's Al Mar glows green. I don't think it's detergent or anything like that, my gunting's almost NIB and only one side glows green like ThinkOfTheChildren's. Shifthrow - it might be you light, or you might have a Military made out of the same type G10 as the dimple side of the Gunting. It almost makes sense for the side with the dimple machined into it to be different, but my friend's Gunting is all black under the light.

I think you guys have all been staring at your velvet Elvis paintings for too long.

Man, I thought you guys were full of it until I went and tried it in my daughter's room (she's got it set up like a disco!)and damned if the left side (not the right) of my black Gunting doesn't light up pale green!!

So I tried everything else in the house made out of G-10. The only thing that lit up was the live Gunting! The drone didn't and niether did a Laci Szabo neck baby in G-10.

Strange happenings?!/!?

Maybe this intentional and somehow used by Spyderco in the manufacturing process. Maybe to identify which are left and right prior to manufacturing.

This would seem pretty useless. Any given scale can only fit on one side of a knife (unless the knife's butt is symmetrical to its pivot). Plus, my Gunting's side which lights up is different than V. Oller's so there doesn't seem to be a consistency.

Burke's hypothesis of the black light picking up on the woven composite (depending on the grind direction) makes sense. The only problem with this theory is that the edge of the G-10 lights up also, not just the checkered part.
 
You're not gonna believe this, if you place your Gunting under the black light while playing Jimi Hendrix, "Purple Haze" it will...

Sorry had a 60's moment....
 
Just another part of this phenomenon which I noticed (It probably doesn't mean anything but it's cool):

When all of my lights are off except for the black light the g-10 appears as lime green. When a regular light is on in addition to the black light (as in my picture above) the g-10 shows up blue (as in my picture above). Cool effect

So if I buy a Gunting I'm going to have to check it with a black light. I want it to light up blue.

I tried several of my G-10 handled knives and they glow green also. I think that there is some sort of dye added during manufacture.
Sort of like the dye added to the coating applied to some printed circuit boards. Of course your mileage may vary.

I tried this with my Carnie, and both sides were green!!

"What's that?"
"Oh, it was under regular lights and the handles are green....never mind."

I think it has to do with which side is against the body. My buddy Jimmy Clifton came by last night and we tried it with his Gunting.

He's a lefty and carries his in a Skunk Works on his left side, I carry mine on the right. The only side that glows pale green is the side towards our bodies. Some thing in the sweat combining with the G-10, maybe?

V.Oller,

a good theory but I carry mine on the right side and the outside glows so it's not from my sweat. Another reason I don't think it's a foreign agent is because the glowing is so even: it doesn't look like something got on the g-10 and discolored it. I suspect that whatever causes it is a result of manufacturing, not the customer.
 
Ok, now how many of you live near nuclear reactors? Be honest.
