Here's my test.

This is a 6.5" thick dried hemlock log which is super hard stuff.
I chopped through it with this Bowie that I mad a few years back and it could still easily shave hair after.
I have chopped down trees a foot thick with my knives, why not.

Here's another knife and another 6" thick log, this one dried fir.
I chopped a dead dry alder down with the same knife minutes before this.
The knife shaved no problem after cutting both logs.

This is my version of the ABS 90% vise bend.
That 52100 is tough stuff. Here's the rope cut video.
It's a free hanging 1.5" thick Manila braid tug boat line, and it's a lot harder to cut through than hemp.
