Hi guys, I just recently received and BM Mini Grip and enjoy it a lot. However, I noticed that the (nubs?) from the axis lock kinda digs into my thumb and hurts a bit after frequent opening and closing. Is this basically just because of the shape of the nub? I also have a SOG Mini X-Ray with arc lock and it seems much more comfortable on my thumb and perhaps even smoother compared to the Mini Grip's axis lock. Anyone else here wanna share their opinions? Maybe my thumbs are just thin skinned?
