I don’t believe it’s discontinued, but you might want to ask this on the Spyderco sub-forum, you might get an answer from
Sal Glesser
himself!
I love the Chaparral and have a few different variants and Raffir Noble is my least favorite. It’s very smooth and gets slick when wet and the scales take micro scratches and tend to get a little “cloudy” with use.
I’d suggest the Lightweight, my personal favorite, but the CF or Sun/Moon versions are great too. The stepped titanium is awesome but kind of feels like a different knife due to weight and balance. Those are discontinued and probably only available by resale.
You can’t go wrong with any Chaparral!
