The Toughest PM Stainless

Awesome! Thanks for that video. I’m sure I speak for all of us when I say we all appreciate this.

If there is one constructive criticism I have it’s that it seemed the number of whacks against the hotel pan as well as the hardness of the whacks was not the same for all the knives.

I counted 15 whacks for the cpm154 and elmax, but 19 whacks for the s35vn.

I can’t be certain about how hard you hit them but for some reason I felt that the elmax wasn’t hit as hard.

I appreciate the criticism.
Especially if it's constructive.

Thank you.

Yea, I want this to be an interactive experience for us here on BF.
Should be fun.

We can redo that test in a more controlled manner.

I'm open.

I was just exhausted from work and all the talking and wanted to just get it done.

I originally was biased about CPM154 just being tougher just because but let's go into this together without expectations and just observe what happens.

If anyone has requests within reason. Let us know.

Let explore together.

What would you need? Just a slab of 20cv in some thickness from US Knife Supply? And then you'd hack it into the same form as your other test mule blades and rerun the tests (this time, with Elmax at the 61 sweet spot, just for me :-))? I'd be glad to chip in and help fund a 20cv or M390 test, as well as for another chunk of Elmax assuming you need a fresh blade to do the HT.

Dood. You're getting into the steel testing business. You and that Pete guy (from https://www.everydaycommentary.com/) should collaborate and design awesome tests around common questions that the BF community has, ping the rest of us for funding for your time and materials, and publish the results. I would gladly chip in one-off funding, or even be a regular 'subscriber', to something like that which would run systematic, unbiased tests with no commercial interest driving it.

Maybe you could build something like an arm on a pivot at the side of a wood block. You put the knife at the end of the arm and pull the arm back to say 90 degrees. (Perpendicular to the ground) then when you release the arm the knife drops from gravity.

The pivot could be as simple as a greased nail driven through the arm and into the side of the wood block.

Yes, I've got something even simpler to try then we can go from there.

But I really want to do some more destructive testing with these blades so we'll move on afterwards.
 
Not sure what was used to make the pan. It looks like some kind of plastic. If so, and you say you're getting deformation instead of chipping, then this was more a test of hardness than toughness. The harder steel would have an advantage. As the impacts get more energetic, toughness will be more and more important.

I believe the pan was metal.

Its metal, it's in all my sharpening videos so it's nothing new.
Don't worry my friend, these blades will be destroyed
There purpose is to be broken.

Like I said, we will RAMP up to it so we can learn. If we just out right break them then we don't learn Sh#@
 
It didn't sound metal, but it is full of water and stuff, and on a YouTube video. Regardless, a deformed edge is an indication of insufficient strength/hardness keeping in mind this is only the first stage.

If you pay for the lab testing, I'll have the pan analyzed for you :p:D

JK, I appreciate the observation

I'll just sell ya the whole thing for a good price:p

I'll buy a new one.

I'm tired of cleaning the rust at the bottom.

And these cut marks are an eye sore.

Yea, let's start fresh, I want a new one.

I charge you a bit more then new cause of the added character and what not.

I'll even ship the water too.

:D

Haha
 
Joking aside I appreciate observations and I'm open to constructive criticism.

Thanks boys, we'll get this done after some other projects.

The video wouldn't play on my Samsung-Error.Will a summary of test be available in print? My interest in this is just to make a bomb-proof stainless survival knife with a brute force simple handle.Like the successor to the old 60's Len mail-order carbon folder with steel handle.KISS.
