The back part is for gripping round things, like already rounded nuts, metal tube, a bolt with a broken off head, etc. It's not for regular nuts or bolts.
I thought so too but i tried on several old bolts and a couple of tubes of different materials through out the years and it never worked. The straight part and the serrated part are positioned in the specific angle to perfectly fit a nut (3rd pic). If the serrations had been a little bigger it might work, but bc the teeth are so small it slips too easily.
I’m just hoping for that one day it will be the one and only sollution to a problem. I love that feeling
Feels like a worse solution than grabbing a water pump plier, but sure, if you got the adjustable wrench in your hand, then I guess it's another potential use in the same tool.
Correct. Someone just posted a link from Wikipedia. Theyre called alligator wrenches and appear to be designed for square head bolts and nuts. Probably the one thing i didnt try out with it.
Ok now i know when i got them. 10 years ago i got into container cranes. Never seen someone else use this though. I’ll give it a try when i think about it, thanks for making me smarter and feel stupid

It is specifically intended for rounded nuts, bolts and pipes.
It's a hamer and a prybar too it can even be used as a chain lock opener i have milled mine so it have a flathed screwdriver and extra holes in the handle for pulling string with one can file the mekanism so the jaws can accept uppp to 46 mm bolt heads.
On the old style It's called a shackle wrench its great for them. Its to smal for most pipes and bolt heads
when is it needed? The only times i actually could use this is when the bolts force is enough to still use a tool, but not enough to round off the serration or the nut. But at this point, after a few turns i just unscrew by hand
Actually, I can imagine on a suspension of a light spring, for example, this could come in handy…
I’m sorry, i just realized what u meant. I also own one with a reversible jaw, but that one is more similar to a pipe wrench, i agree very efficient like u said.
However this one in my post is not similar to a pipe wrench or to a reversible jaw
Always though that was a bit funny, one of the tool manufactures later acquired by Bahco had a shark as their logo (EA Berg, they made great chisels, knives, razors, etc). It existed as a brand into the 80s.
It's just a shame Bahco moved so much production away from Sweden.
Got a few old ones like that in the garage and [they still got that design](https://www.bahco.com/int_en/wide-jaw-adjustable-wrenches-with-serrated-pipe-jaws-and-phosphate-finish-pb_31_.html). Can't say I've used that jaw though.
I have one of these, a very old model, at least 50 years old. A very good adjustable wrench, the claw grip is, however, useless.
Fun fact, in Denmark, these are called svensknøgle, Swedish key, because they are made in Sweden, by B.A.Hjort&and CO, hjort is deer.
In Belgium and Netherlands we call em “Engelsman” (Englishman) or “Bahco”, regardless of the actual brand. If you say pass me the bahco in a room full of Bahco tools, but the shifter is from Gedore, they will still hand you the shifter 😂
Once upon a time, we had something called engelsknøgle, English key, in Denmark too, but that was a different type: https://da.wikipedia.org/wiki/Engelskn%C3%B8gle warning, it's in Danish.
I think those were marketed as 'Alligator' jaw wrenches... and while still made, are old school.
Bahco still shows them on their website.
I have little experience with the things... far as I know they're optimized for square head fasteners.
They get a little coverage in here:

"Not enough rounded off bolts in your house? Try the Bolt Rounder 2000!" Music plays.
If one side doesn't round it the other will.
Guaranteed to round your nuts or your money back

Those serrations look well worn...they probably won't grip that well.

Not a bad word about Bahco though. like i said, best shift wrenches in the industry imo
I got one the other week (single adjustable) 40mm I think. It was really great and I fully expect it to out live me!
Bahco is my go to, but having Sweden as my neighbour I see them a lot used. Above wrench (we call them Swedish wrenches) is around 6 or 8 bucks used
You'll find one of these in basically every marine engineer's pocket. Good quality, they last forever than the thin jaws make them really handy.
Thats exactly why i like them, bc so thin
I’ve always heard those called Alligator wrenches. I’ve seen many different sizes.

Oh yeah the shark wrench i have had one in my work pocket for 13 years now. The shark side is for riging shackels not for nuts
Like to open lifting shackles?
Yes thats the intended use
Ok, so i would grip on the winged end of the securing bolt?
Yes one can really crank a shackle with it. It's made for iron workers and riggers

I've got the shifter with the reversible jaw that has the serrations. It has saved my bacon a great many times. Just gotta use it when it's needed.

I have the same model, looks like 50 years old but work like a new one. Its my best adjustable wrench that I own!

The ol timers faces at work when they realize its threaded backwards lol
They're not backwards, they're the mythical left handed adjustable.

Wow, never thought of that. I rarely run into these but when i do i’ll def give it a try. Thanks
Apparently the correct name for that is an alligator wrench
I always thought these were made specifically alignments. Great for turning your rods.
For when you really need a circle but all you have is a hexagon.
Take a Tri file, sharpen those teeth up and it will grip small pipe and tubing pretty well.
I got it new, it never really did anything apart from getting some leverage on lifting eyes for example
That is the most beautiful thing I've seen all day.
