I'll try to answer everything that I've seen posted. If I didn't respond to your question, I apologize, and please bring it up a second time if you'd like it answered.
First of all, thank you to Peacefuljeffrey for retracting your comment there. I felt it to be a little harsh, and it is a true sign of solid character to remove such a post. I very much appreciate it.
Next, the issue of the Razel-like tip protruding from the handle has come up. This is very much the case, and if I were to grind a Razel tip on it, I'd drop the spine a little most likely with an angular grind. I think for what I use this knife for, the Razel tip would be the most useful configuration for me.
The item used to baton the knife when it failed was a very wooden piece of fence post.
Using the framing hammer the first instance in which the knife was batoned was only due to the fact that it was an enclosed space and a piece of 2x4 or similar wood would not have enough distance to generate the momentum needed to get through the flashing. I did not have the right tool for the job on that day because 1) It was one of my first days working that job, and I had the bare minimum tools. Thus, I did not expect to have to cut through flashing or any other metal material, as that normally isn't part of the job. 2) It was snowing that day, so all the wiser, more well equipped crews had left early.
Sal, thank you very much for taking personal concern into this manner. That just goes on to strengthen the appreciation I have for Spyderco and the commitment that you folks have to your customers. That being said, I think I may modify the grind on it myself. I think the Razel-like tip may work very well for the tasks that I come across during work.
In my opinion, this was not due to the materials in the knife. I would venture to guess that one of the small indentations made by the prior batoning with the hammer acted as a stress riser, creating a weak point at the point of the break.
J85909266, I've definitely considered going the fixed blade route, especially from the company that I'm assuming you're alluding to. I think at some point in time I am going to break down and at least try one out.
I think I'm going to have to get another full flat grind blade, but not for work use. I have enough beaters to choose from that serve me very well at work (CRKT M1, Benchmade 705 in D2, and now this Manix). I've had my eye on something in ZDP for quite some time, and next weekend, I'll be in Calgary, home of Target Knives, so we'll see if they've got anything in ZDP, let alone with a full flat grind. Who knows... I may find something that'll make my Sebbie nervous..
Again, thanks for your posts and your opinions, folks. Feel free to add more if you've got it, although I already know how stupid I was. Reminders are unnecessary.

Heck, gimme a break, I'm only 19 and still learnin'.
