What a bad, bad day.

What in the world happened? Did you accidentally bend the blade side to side?
 
I know from heavy chef's knife use, sometimes a bone hit or a prying or side to side force can create structural cracks on the micro edge. Later in use the metal edge breaks when just the right force takes place.
 
Could always drop the point a little, bring the cutting edge up, kinda in the fashion of an Arete... could be a super cool bushcrafting tool!
 
That'll steel right out, won't it? :p Seriously, sorry it broke. You could grind the blade into a shorter configuration and save the knife.

I just put the tip in the piece of wood (thats in the photo) and then bumped it on the block so I could split it and it didnt split.
 
Dude, sorry to hear that happened -- I would recommend contacting Andy offline to see if he can help you out on this. From reading previous posts, he's pretty good at triaging failed blades to identify potential modes of failure (ie. stress risers, bad HT, etc.). Hang in there.

Thanks. I sent him an email earlier today
 
My Hunter and I feel your pain. Mine is 3/16" and pretty stout so I'm not going to baby her :D I trust Andy will be his normal nice self if anything weird happens during use
 
Actually based on the pics, you might have lost .5-.75, which would make it a perfect bushfinger!
 
Bummer man, I feel for you.

Looks like it had a good life. Sometimes knives have been used for their useful life, but it certainly doesn't look like yours is in that category.

Just out of curiosity, what are those horizontal scratches from on the blade? How do you sharpen it? Was the edge damaged at all?

Bleh... I hate to see that. I dropped a knife that I've been making, point first, into the concrete garage floor the other day. Fortunately it was before heat treat so it rolled up instead of breaking.
 
I'm trying to figure out what happened here. I've never seen a person try to split wood by penetrating the tip into the wood like that. Just so you know, in my opinion, this is going to be the cause of this damage. Drilling with the tip, I get. To penetrate the tip into the wood first is something new to me. I've never once driven the tip of my knife into wood. These knives are designed for light batonning. Why wouldn't this kind of cut be used in this scenario?

Send it home. Both pieces please. I can look at the pieces and may be able to determine whether this was an exsisting stress crack, or whether you just broke the tip off of your knife. If it is an exsisting stress crack, then I will replace the knife. If you broke your knife driving it into wood, then I can fix it by making it shorter and re-grinding the bevels. No charge either way.

This is the third time a knife has snapped on me in over 4000 knives. Each time it has been during lateral pressure maneuvers. I believe that is exactly what happened here. You can see the blade was driven into the wood cross grain. So when you 'bumped' it, the grain structure of the wood caused lateral pressure.
 
Thats it in a nutshell ^^^^^
Looking closley at the blade scratches it appears it wasnt the first time it was driven tip first
