Hello, newbie question here. These tweezers don't open as widely as others I have held from Bergeon, Dumont, Regine, etc... They also require such a light "squeeze" that they slip out of the fingers if not supported from beneath by a 3rd finger. (Bergeon 7421-PM-S5 purchased from a large, well regarded watchmaking/jewelry distributor here in the US)
Is this normal? Do they need adjusting? Or, is it better to ask for an exchange/refund? My personal inclination is to tinker with them and try to adjust them myself, but I wanted to check in with you all first.
Thank you for any help and
