I have several Case Delrin Sodbuster Jr, I like to touch them, there is some sensuality, the same for my Quee 70. I have also a Sparxx jigged delrin Trapper and Baby Butterbean. The feeling of the trapper is not as comfy as smooth delrin.
I did not use it for month in fact, just because jigged bone is way more agreable to touch. The butterbean is a bit different as much smaller. But If I had to do again, I would not buy these two knives with jigged delrin, rather get smooth or bone.
