I have a rare talent for finding fault in anything and the pressed-fit thumb studs are my complaint about the Buck Slims. My Slim Select thumb stud came completely off the blade and I refitted it with JB Weld. I carried it for another year and then gave it to my brother, with no problems so far. The stud on my Slim Pro came loose enough that it rotated when I tried to use it to open the knife, sometimes causing my thumb to roll off the stud. I fixed it with Loctite and again, so far, so good. I tried looking for replacement studs from supply houses, but the specifications were too vague for me to be confident of a fit. I considered tossing the studs in the bin and opening my knives one handed the way I did before they put those stud thingies on the blades. Buck makes a nail nick version of the Slims that I wish they sold in The States, just sayin'...
