I think the mini-Griptillian versions are better. Stock, I like the knife, though I only have RSK versions. A decent small pocket knife for a fair price.
The full-size Grips just don't feel right to me. I do have a couple, RSK versions, and I reserve these for pack carry "extra" knives. They are useable and perform well, but I have so many other knives to choose from to carry on my person.
If investing in some after-market scales, the full-size Griptillians can take on a whole different feel. But at that point, the knives really aren't Griptillians anymore IMO.
