Dig it.

Is this indicative of a hardness differential between surface and core or unrelieved stresses?

When I tapped it near the pivot it just exploded.

Now I feel like a sucker for ordering one.

So what should I do with it when it arrives? Maybe I'll use it in the garden to dig up weeds.
 
Pack them up and I'll see what my old lab can make of them (assuming they want to play with them).
 
Send me a mailing address and I'll mail them when they arrive. They said 3 weeks for delivery so there's maybe 2 more weeks until I get them.
 
I'll probably buy a random one so that we have a broader range to see if the guys are willing to run some metallography on them. If nothing else they should be willing to shoot some good magnification images of the fracture faces and if they're feeling frisky they might slice the face and polish it to get some flat grain sizing.

Looking at Sam's pics blown up is interesting.
 
Sam,

This is what large grain size looks like when a 1095 blade breaks from not being properly tempered. See how even and regular they look? The grain in that thing of yours is enormous by comparison.

That's the thing about knives...the single most important aspect of their performance is completely hidden within the blade's construction. Of all the things I'm willing to cheap out on, knives just aren't one.

As dad said, 'When do you use a cheap knife? When you're wearing your cheap fingers.' :)

I received my 2 knives today. If you guys want them for testing, send me a mailing address.

Also, thanks for all of your testing and reporting. You saved me from possible disaster that could have resulted from using substandard knives.
 
Both of yours might be just fine. Inconsistencies in materials and heat treat may be at play here.
 
I gave both knives a quick test. Did a few tear outs on a 2x4 for each. Nothing major, just some 1/4 inch stabs. No failures.

Then I placed the blades flat on the 2x4 and gave each some taps from the hammer of my trail hawk. I didn't want to hit it too hard in fear of having shards of steel fly in my face, so I tapped the blade, steel-on-steel, about hard enough to shatter a beer bottle. Gave the blades about 6 taps each the length of the blade. No failures.

Good tests.

Find a brass rod and place the cutting edge at an angle and see if the cutting edge flexes a little and returns to shape or chips.
