Go for it Timmy, I have never started a fire with Cylinder Block, but I am open to new ideas

i am no expert but i know what certain steels can handle, 1095 can take a beating but it will chip badly on a equal or semi equal harden surface like a cinderblock, other high carbons will act similar

I think maybe I will try this at some point
Above you did say MOST knives.

I can say with personal experience that a Condor Kumunga using 1075 took as much damage from chopping off a few Wood Grouse heads and some Raccoon feet, as my TGLB did striking into a Solid Paver block....This indicates to me that 1075 is certainly not a hard use material...

yes most knives are not subject to the same heat treat as busse, good steel is only as good as the heat treatment

Not sure what this proves??? It proves that the steel is exceptionally tough. The edge is 25 dps. I will repeat myself......try that with any other knife. Lets see how the edge holds up. Does that bother you that I push my steel to see just how durable it will be in a situation i hope I will never be in???
Doesn't bother me at all. Didn't mean for you to get
densive, just was wondering if I missed something. Agreed, it is tough.

For me, the key points are how infi takes damage, compared to other steels, followed by how repairable it is.
I've had other premium and supposedly hard-use knife steels chip when, for instance, hitting a bit of grit embedded in driftwood, or chopping through a surprise knot, or being dropped onto a rock (or concrete). Sometimes this has happened shockingly easily. And I do mean chip: where the stress has broken off a small piece of metal from the edge leaving behind (usually) a sharp angle in the chip. This itself is now a serious weak-point liable to further damage as it concentrates forces in the angle of the chip further into the steel. Repair requires the blade to be reground to above the level of the chips, and hope that there isn't invisible damage within the grain structure that's left, waiting to crack.
Infi doesn't chip. It's been said a thousand times or more that it plastically deforms when under the same stresses that chip other steels, or at worst it tears. This means no sharp chip angles to continue the damage. Also, due to the very same properties, a lot of this type of damage can be steeled out, restoring much of the steel to where it was and without needing a full regrind. Infi responds brilliantly to this, compared to other steels at a useful hardness.
I once accidentally tried to hammer the thinned-out (15-ish dps) edge of my HHFSH through a big hard sandstone rock. I was half drunk, it was dark, and I was splitting a log leaning against the rock. As the knife stopped moving, I just hit it harder (and harder!) with the batton until bits of flying sandstone caught my attention.
The blade was damaged for about half an inch along the belly, crushed inwards by perhaps 1/16th of an inch at most and slightly torn along the very edge. There was not a single chip though. That did need some regrinding after steeling back what I could, but I pretty much guarantee (from personal experience) that any other non-infi knife I have owned would have suffered considerably more lasting damage, and most would have been outright ruined.
So yeah, chopping a cinder block might in itself not prove much between infi and some other hard-use steels, but in the extreme, infi will still be serviceable afterwards while the others... not so much.
The bottom line: I can abuse infi and know it will carry on kicking; experience has shown me that I can't feel as secure with other steels.
ETA: Oh yeah, and it can do all of this and still be practically stainless (essential for my alien-acid sweat) and looking as cool as anything

Here's a few pics of my B11 after I was chopping camphor laurel and vine roots out of the ground. The sweep of the blade continually hit rock as I chopped. They were full blooded swings and the blade would have come in contact with the rock at least 2 dozen times. Minimal damage. I would expect any other non Busse knife I own would have failed after a few hits, at the very least large chunks would be missing.
