That's why Eagle Grip died. Vice grips, particularly used in welding, one of it's primary purposes, turns Vice Grips into spatter covered trash rather quickly. Why Eagle Grip figured it could charge $60 a pair for something most of us consider to be disposable is a mystery to me.
^ It is possible they mistakenly assumed that welders would use some other kind of clamping device.
For years after Newell-Rubbermaid bought the Vise-Grip brand, people who used locking pliers regularly were lamenting the decline in quality.
According to posts on GJ, from people who supposedly lived in the town with the original Vise-Grip factory, the first thing Newell did after buying Vise-Grip was to change the specs on the steel to a lower quality, cheaper steel.
There are various purchasers for locking pliers, and one of those groups is welders, who simply use the pliers to clamp pieces together quickly for welding or braising.
The pliers used for welding get gunked and trashed quickly, so lower cost is important, although better steel alloys will last longer in these applications as well.
The other major group of people who useVise-Grips, need a plier that will lock on like a rabid pit bull, and hold onto whatever part needs to be torqued due to rust, or permanent Loctite, and then have the locking pliers hammered on or torqued with a 6’ cheater bar.
This second group of users basically need locking pliers made to the original Vise-Grip specs, or the Malco specs.
Most users aren’t going to differentiate between the licking pliers though, and don’t want to spend the Malco/Snap-On prices which cost more than a pair of Knipex chrome plated pliers (the regular ones, not the locking ones) for a tool they will weld with.
Because of this, there wasn’t a large enough market for the higher priced locking pliers, to sustain production in a facility that only made locking pliers.
The Facom pliers that open ridiculously wide give more versatile use than the older Petersen design, which is the reason Facom can keep these in production, as well as the fact that the producer who makes the pliers for Facom/Stanley also manufactures other items.
