I tested the joints in the Snap-on cutters and needlenose vs. the Knipex. The Knipex joints are good but the Snap-on joints are perfect. Zero side play. They have no side play but they open easy enough and close easy enough. I have used the SO linemans as well. Other than linemans when doing electrical twisting I really do not want pliers that "fall open". I consider that a sign of a cheap worn out plier. The Snap-on solid feel is what I consider ideal.
Do your Snap-On cutters / pliers free up over time?
Some guys stated that they have used Kroil/etc to try and weep into the joint to not make them so stiff and loosen them up.
Good contrast is Klein and Knipex linemans that I have. I have two pair of Knipex and two Kliens. (Difference sizes) Kleins are super stiff out of the box - it takes considerable force to open them. I do expect them to loosen over time. Knipex linemans on the other hand 'fall open' brand new...I'll have to double check if any of my other Knipex 'fall open' but I do know both of my Knipex linemans do...I'm pretty sure I have some Knipex need nose that fall open.
