I have a couple of knives (Case & Buck) re-handled in stuff call 'Mica Pearl', which I'm guessing might be same/similar stuff under a different name/trademark. Same colorful, swirly, irredescent character. I do like the fact that each piece is different in color & swirl patterns. Haven't used any of my examples very hard, but I don't think durability will be an issue (real 'abuse' notwithstanding). I think Hen & Rooster has been using something like this for quite a while, and haven't heard of any quality issues there, either.
Nice thing about modern synthetics & plastics, seems like across the board the vast majority are much more stable & durable than those of 20+ years ago. I wouldn't worry too much about this one, especially since Case is building it into their own products, even if it's an SFO. Still covered under their warranty, I'm sure.
