Supporting Unreasonable Edge Usage?

[BluntCut MetalWorks]

Can a paper slicing edge cuts stuff against metal backing (anvil face) and afterward edge still slice paper without tearing or skidding?

Please show & tell your edge

BluntCut MetalWorks Thank you for the demonstration. What steel is that knife made of?

You hitted an anvil with top portion of the blade several times
then you cut paper with middle/lower part of the blade

:^D

did ya watch the same video I did? sure seemed he hit anvil with the flat right before the belly of the blade. he then cut the paper about full length of the blade on the second cut, other than the very tip of the knife.

Is there any practical application for this type of test ?

Maybe cutting up your dinner on a steel plate ?

 

[Zulus]

I'm half serrated blades guy
So I may use different parts of the blade for different tasks
As in attached clip
:^)

The HRC difference between the anvil and the blade must be huge.

Well, this -- CPM 10V 66.5rc 13 dps Edge Test Cut Antler and Power Cord -- also consider as 'unreasonable' usage

Seriously , I feel that it's important to push the limits and try new things .

That's how we learn, improve , and progress .

Might as well test cut on a ceramic surface

Result: Lost phonebook paper slicing edge, need a sharpening touchup. *note - lower hardness edge would flattened more

Considering my family has one of those glass cutting boards this would be better lol

This edge would slices/marks onto glass however edge would still be dull, perhaps a little less than ceramic surface.

Thanks for doing and sharing your cut tests man! It's always good to see this type of stuff. People cutting on a ceramic place always makes me cringe the most other than people cutting through the cardboard sleeve around All-Thread and the edge going through the cardboard and grinding against the hard threads on the all thread haha.

Awesome demos!

Ok - weird question also…

I’ve hesitated to make a whole thread out of this, but does anybody use plates of a particular material (wood??) to eat steaks on with sharp knives? I’ve always wanted to do something like this but I’m not sure I could eat meat off a cutting board in front of my wife without a little ribbing from her.

I cut food on my kid's plastic plates a lot. I consider it a plastic cutting board with a lip at this point.

If I remember correctly Cliff Stamp was cutting copper with thin blades for quite some time, and it was part if his regular testing.
Kinda funny to think about it but a copper plate would probably make a good cutting board because it's both hygenic and relatively soft enough to be easy on a knife edge (especially compared to glass or marble).

Personally I've found staples in cardboard to be one of the most dangerous things a knife can ever encounter, you're usually cutting fast and then suddenly the blade stops or glances out of the cardboard, high impact at odd angles.
OLFA blades are still the best thing for cardboard because the 1mm blade stock is so easy to sharpen (and they do run the steel hard so it will hold an edge).

This design promotes tip only contact (by disinclined other part of the edge to contact) with hard surfaces. Also preserving most plain edge functionalities.
