Busse vs Chain

Case hardened chain is HRc 63 or 64. You can tell immediately by trying to hacksaw it - the blade just skips along the surface.

I wish I had a video of me trying to cut hardened chain about 25 years ago with a bolt cutter. Couldn't cut it holding the bolt cutter in the conventional fashion, so I put one handle against my chest, and took both hands and pulled as hard as I could towards my chest. I had a fat lip for a week after the $80 Rigid bolt cutter jaws broke and I punched myself in the face!
 
If those bolt cutter jaws were INFI...
Just razzing, Gents. I know the limits of INFI.
 
OK the chain is most likely not made from case hardened steel but rather just plain steel. Most knives including the higher end designer ones would probably not fair as well.......... ;)

A carbide rope saw would have made short work of it with out the fat lip... ;)

"INFI- For a long time INFI formula was a secret. Apparently due to laziness of the labs :) And another factor is that just the formula doesn't make a great steel. There's more involved and on top of that, heat treatment is proprietary too. Later, somewhere in 2004-2006 one German lab did the analysis and the exact composition they published was as following: C 0.5, Va 0.36, Cr 8.25, Co 0.95, Ni 0.74, Mo 1.3, N 0.11. As you can see besides the usual steel enhancers like Mo, Va, Co INFI contains Nitrogen. It's kindda unusual, but works very well. 8% of Chromium also explains INFI stain resistance. The rest is still a mistery. With pretty much ordinary steel components getting this such a high performance"

and yeah i'd try it if i could buy it with the heat treat formula
 
Damn, I cannot understand why anyone would wreck a perfectly good knife like that.

I would have treasured that knife for years, cut many steaks and turkeys up with it, chopped wood until the cows came home and at the end of the day just wipe it down and put it to bed in my sock drawer, as good as new and ready for the next job.

What a waste....

I raise your wimpy 11 mm hex cross section security chain, to a Almax series 4 rounded square cross section 19 mm quad tempered security chain.
