surely thats not an adjustable spanner but some sort of pliars?
Its not to obvious from the pic but unlike pliers the jaws have a parallel actions like an AJ rather than the scissoring action of pliers – so they fit the nut like a spanner but grip like pliers. Theres a very high leverage ratio so the grip things very tightly too, but the gripping faces are smooth so you can grip without marking stuff. With a bit of practice with how you hold them you can use them as a sort or ratchet too – good for hard to get at bolts and much faster to work with than an AJ. They’re really light too, mine is usually in my pocket all day.
What’s a chisel knife used for?
Chiselling and knifing 🙂 Basically you can use it like a knife or strike the end of the handle like a chisel or strike the back of the blade like a side-strike chisel or hacking knife.. That point where the two cutting edges meet gives a good stanley-knife like cutting and marking function too
They’ve got a bit more spring to them than a conventional chisel so you can lever and pry with them too without them snapping and they’re thiner than a chisel or a cats paw so good at getting into stuff and prying it apart. Easy to resharpen and dead cheap too so you don’t need to be precious with them.
The first time you use one you’ll cut yourself.
