A number of online tool shops are calling these “the ultimate locking pliers” for good reason: they don’t “pop” and jump off your workpiece when released. Instead, you release them by firmly squeezing the top and bottom handles together.
Other cool features:
- The adjusting screw is completely enclosed in the handle, preventing you from gumming it up with crap (or welding splatter).
- The adjusting screw is fine-pitched, offering very accurate adjustment to let you put just the right amount of force on the locking mechanism.
- A fixed upper jaw lets you clamp the lower jaw in a vice if needed.
They’re a little pricey, starting around $30, but it looks like they might be nice to own.
