In February I acquired a blue handled mini-griptillian with a thumb-hole opener (model 555-BLU). Although it's a great knife, I find the thumb-hole to be a bit harder to open than I would like and am looking for a mini-grip with a thumb stud. My knife has hardly ever been used (I've opened a few boxes with it) and has recently had a touch-up sharpening just to make sure its in top shape. If anyone has a mini-grip with a thumb stud and would like to get a practically brand-new-with-box replacement please let me know!
