Nope. The whole knife kinda "flexes", always did. When I first got it, I was using a Sebenza, which is solid as a bank vault, so I thought "this Spyderco is a POS". It hasn't gotten loose though. Still same as ever. Really made me like VG-10 too, as a favorite steel. Maybe it's just this knife. I re-profiled it to sub-30, and just maintain it with the sharpmaker at 30. If my wife asks for a sharp knife, and I give her anything but this, she says "No, the sharp one". Funny thing is, the sharpest knife is an Opinel. I push-cut spray foam with the thin-bladed Opinel.
