Wrench Chromium Vanadium Steel Multi Functional Adjustable Self Locking Ratchet Open End Wrench Manual Repair Tool

The key was tested at work, a rusty 3/4 tap was unscrewed, although it had to be extended with a pipe, the grip is reliable, the edges bite in, there is no slippage, I will try larger ones later

The key is universal, good, massive, solid. I liked it, thanks to everyone.

Looks solid, good quality. The spring works well. Haven't tested it in action.
