Kman,
This knife is a kraton handled version of the 119. Buck offered these knives for a short period in the mid to late 80s. They were discontinued due to soft sales. The knives are not collected by many, though a few of us have them. Most people like the way the knives are tacky to the touch but found them to be rather plain in appearance.
I believe Kraton is a material developed by Shell Oil but I could be wrong on that.
Hope this helps.
