A test for *any* decent cutter is piano wire. Properly hardened jaws

You are an idiot, and a troll.

Piano wire is cut with a heavy shear, not a nip cutter. There are no
nip style cutters made meant for steel with the exception of bolt cutters
and they are a completely different animal. That is why a block shear
cutter is used.

Try learning something about tools. It's a standard test to check the
quality of side cutter jaws. There is no difference in principle between
cutting any sort of wire.

You're an idiot. There is a HUGE difference between pincer type
cutting and shear cutting and both are used in the industry, dingledorf.

If your favourite brand fails this go get a decent one.

Wrong. It is the standard "destructive" analysis. There are other
methods for testing the hardness without damaging the cutting face.

Also, they are not all tested that way. There are softer materials used
for lighter duty work media, and they get tested differently.

As far as "what any cutter can do..." goes, the construction of the
cutter determines its correct usage limits. regardless of any cutting
edge hardness tests that may or may not have been specified or performed.
Not only do the edges have to have specific hardness ratings, but the
meat of the cutter jaws have to be designed heavy enough to be able to
withstand the forces a given size and type of wire proposed to be cut by
it, as well as the shock wave that traverses through the jaws at the
moment the wire snaps and the cutting edge 'mating faces' close together.

THAT is for pincer type "cutters". Shear type is a different test
standard. Not that you would know about such things.

I know more about tools than you ever will.

The FEA analysis on your skull comes back with a reading of "Hollow
structure found... Analysis halted" Even the phrenologist nearly
vomited.
