Man, we're an opiniated bunch!!!
So, I'll toss my ought two cents worth in...
I don't really care for GBone for two reasons -
1) It usually looks too gaudy and sorta fake to me;
2) It's cold to the hand, much more so than jigged cowbone.
Now, do I own any to make this observation? Yes, one, a folder I picked up at the OKCA show several years ago. I really liked the knife, it's design and the overall craftsmanship, and the color of the handle is a kind of grey with darker veining, which I felt wasn't too gaudy a look. It's the only one I own with GBone, and through carrying and handling it, I percieve it to be somewhat cold to the hand no matter how much I use it. Now this could be 'cause it's smooth, unlike jigged bone, but I doubt I'll buy another one unless I REALLY like the knife for a lot of other reasons.
But also know this is just my opinion... And as I've stated in other threads, I'm no fan of stag, either... But I do own a few!
So in the end, it depends more on the overall work, but I'd be more hesitant pulling the trigger on another GBone knife due to my own personal observations...
