PICS TO COME LATER ON THIS MORNING...


I ground out a blade, CPM154, stick tang fighter bowie shape. got it back from HT a long while ago, and finally picked it up to finish. Was polishing it up at work on the 8000 grit stone, and I noticed it. About two inches long, center height of the blade, running from tip to butt, half on the blade through the plunge and into the ricasso. I do not believe it is from the HT or blade shape cause it did not originate from an edge or grind. It starts in a random spot in the steel. Might have been in the steel along, I dunno. What peeves me is that I find it now. Not before I paid for the HT, not before I dumped a buttload of sandpaper into the effort, and of course not before the hours of elbow grease hand sanding. :mad:

Okay, enough of the whining. Time to grab another piece of steel and start grinding. My bro wants SOME sort of knife, even if it is not originally what he wanted. Who knows. Maybe what I make this time might be more badass than what I was already making.;)
 
I have never seen this before on stainless. I have broken stainless once from driving on a too tight guard with a hammer. That stuff is brittle if hammered on.
Can you get a good picture up of it?
 
When you say, crack, do you mean an actual gap, or just a fine line?
I seem odd that it would not have been noticed before the final polish?
Could it be a line in the steel ( alloy banding ,perhaps), and not an actual crack?
A good closeup photo would help.

I feel your pain! I pounded out a nice section of W2 and started forging it into a 10" blade and screwed it up as a result of how hot I was running my forge!
Forging 1.75X.75 rectangular section of W2 with only some hammers just to screw it up sucks!!!

Or forge out a knife and put it in a quench just to realize you screwed up the steel and make it soooooo brittle that about a half inch of the end of the blade cracks off with a touch of a hammer like it was softer then an egg shell.

It just takes some time, patience, and practice to get right (wish I could skip the time and practice and go strait into making some awsome stuff, patience isn't always my strong suit as you can probably guess).
 
I backed up to 400 with intentions of working back up to 2000 real quick for a photo this morning. While doing so, I ground it out. In hindsight I believe it was a super deep scratch, like I dragged it over the corner of a file or something like that before the HT, and it looked dark cause of the HT discoloration. Weird cause I could drag my nail over it and feel it. Oh well, all is fine now I guess. Just wonder why I did not see it before I mailed it out. I finished it to 800 before going.

So... False alarm.

Stacy, I wish it was alloy banding. That would be cool. Ironically I was looking at I believe pg 396 last night, and found Phil Patton's thread with the O-1 blade with super crazy banding, like W pattern damascus almost. When you have a lot of time and no search function there are THOUSANDS of threads to look over.
