Need more testing ideas for a little necker (Pic Heavy)

I just heat treated a batch of neckers and didn't like the grind on one so I decided to test it to destruction.

Blade steel is 3/32 O1 heat treated in my oven, quenched in peanut oil, and tempered three times at 400

Here is the test knife. I had put a swedge on it but didn't like the way it came out and now that I've tested it, I really don't like it as it cuts into your thumb when you use it for leverage on push cuts. It has a quick pine handle with screws. I didn't want to spend too much time on the handle since it would be destroyed anyways

After sharpening, I decided to cut corrugated cardboard. I was able to get 50 cuts at a time before it needed light stropping. But after stropping it would easily shave again. This is after 200 cuts and would still shave after stropping.

My next test was to push cut this piece of seasoned pine. It handled fine, even when I would pry the blade sideways to pop the new cut off. I expected it to fail here but it performed great. My hand gave out after a while. It would still shave without stropping

So now I decided to batton through the piece with this mesquite stump

And as you can see it is still shaving sharp after going through it - no stropping

Now I decided to carve some antler. This is a skull a buddy gave me that he found on his ranch down here in West Central Texas

It carved quite nicely and needed no stropping after cutting to shave

I also decided to hack at the antler and got some very fine micro chipping but didn't take pictures of it as my camera couldn't zoom that close. It was barely noticable.

Finally I decided to stab the same piece of pine and dig out the wood to see if there would be any tip damage. I expected it to snap here but was surprised when it didn't.

Although there was no tip damage, I did notice that the blade bent slightly, which wasn't a total shock due to the massive swedge I ground in the already thin blade. Here you can see that the tip slightly bends toward the left.

I'm not really worried about this bend as a knife, especially a thin necker, shouldn't be used to pry anyways and wouldn't be covered under my warrenty.

I'm looking for more test ideas before I snap the blade to look at the grain. Any suggestions? What do you think so far?
 
You might get much more useful feedback in the "Shop Talk" forum.

I was hoping to get some ideas and suggestions from knife users rather than just makers but the mods can shut it down if they don't think it fits in here.
 
Hi Jason,

You might try cuts through cow hide, I have butchered a few steers for our families use and the hide seems to dull the best of knives quickly. I love the design and am very impressed with your results so far!

Thanks Sean, I hadn't thought about that. Now I'll be on the lookout for dead cows around here. I honestly might find a few.
 
If you want to be hard on it you might try skateboard tape, sandpaper or something else gritty like that. (I pick those 2 because I've actually had to cut both recently)
 
Not a destruction test, but how about scraping a firesteel, with both the spine and then the edge? Some batoning in the field? Then there's always the bend test, putting the blade in a vice and seeing how far you can bend it?

Looks like fine work and it's holding up very well, hope you're pleased with it!

Old carpet! seriously #1 thing I found that tests edge retention. Having remodeled a few houses I can attest to its ability to dull anything and everything.
 
That's a great looking blade! I know this isn't a hard use test, but since it would be an EDC knife, you could do some food prep just to see how it performs at that.

When will you have more neck knives available?
+1!! :thumbup:
 
Grinder1 - I do not have one of Jasons knives yet. I was hoping to get one in the future. I have had to skin the animals and in doing so had to cut through the hide with hair on. Cow hide can be 3/8 inch thick and it seems to dull knives unbelievably quick.
 
For those who might be interested, look at my signature to see the link to these knives for sale.
