Hands do not get tired, even after cutting a few hundred rings
Spring loaded
Doesnt get blunt very easy
Cons
Only suitable for extra tiny coils after some modification.
Not the cheapest cutters
No flush cuts
Whenever i have to use bolt cutters for anything, i will use this Knipex pair. It will cut through anything, regardless of the material. Not only in the chainmaille sector, but also at work. ( I have more then one pair )
If you want to cut really tiny coils/rings, you will have to grind down the jaws abit in order to fit them inside the coil. Not a big job at all.
Allthough not the cheapest cutters out there, i highly recommend this pair anytime.
