ok I'll admit it, I'm a snippy hoarder, I've got a couple of pair of the mid 1970's chrome Sears, they don't dull but the can break the lower part of the shear, and I managed to bend one and break my finger doing it. I was told time and time again I would F.U. my hand cause I used 2 fingers. Well I could cut the side of a furnace or a 6" opening in a duct before you could plug in your electric shear. Also have bench snips. I had 2 sets in the van and at least 2 sets in the shop. Along with the sears I've got wiss, rigid, klenks, and??? they don't all fit in one drawer.
The worst snip I've every own is one my Father-in-law bought me a early offset, I only used it to cut rust out with. Last year I did some work on my whitney punch dies, one set is in a old worn out tool, I bought for 3$. I called it sloppy! So I pulled those and use the Rocklinizer to enbed tungsten carbide on the cutting edges. WOW it works like new! So excite how well it worked I did my lennox hole saws and the old rusty cutter. Double WOW! Itisn't just me my son used the snip and came down to the other end of the building to ask what I did to the snip because it cuts rust real good! I told him try "sloppy" was he shocked!
I haven't done every tool but man does it work! I'm still using a worn 14" power hacksaw blade in the Keller, it' has cut a whole bunch of 4140, cuts like new. But it isn't as good as a new blade on aluminum.
