Nothing a little super glue and duct tape won't fix!!!!. . . :eek:

Holy Oinkin' Yowza!!!!!. . . :eek:

Many of the custom tips are left fairly thin for slicing as most will never see heavy abuse. . . . Oooops!!! :eek:

The bend/set of the tip is actually very impressive, as any other steel at this rockwell hardness would have snapped long before it took that set. I can assure you that the heat treat is okay and falls within the 58-60 Rc spec. INFI is the only steel that I have encountered that will maintain this level of plasticity at such a high hardness. It would've been much easier to say that the heat-treat was messed up, but the bottom line is that it's a geometry issue and not a heat-treat issue.

In the end it doesn't really matter what caused the problem because the Busse warranty is there to keep you covered.

Send that bad boy in. . . We'll drink to its demise. . . and get another one off to you!!!

Let's drink!!!! :thumbup:

...And that's why I buy Busse knives! :D:thumbup:
 
I would have to think there either was a heat treat mistake, or invisible flaw in the steel. When you see how far AK's flex, just a fluke.

I have seen other threads here with broken infi, usually thinner stuff, where prying was involved.

A lot of people don't think that stabbing puts much stress on a blade, but it is very difficult to do a stabbing motion into any medium with a perfectly straight motion. Most times, you end up pushing to either side, It is a lot of stress on a blade if you tweak it to either side. I think I have seen one or two broken OJ wardens (one was used to pry, took a set, and broke when the guy tried to take the set out by pounding it with a hammer), a broken skelly key (that the guy pounded into concrete, then kicked to break off the tip). With thinner infi it is going to be easier to get it to take a set, but when compared to any other steel in that same thickness it is still strong stuff. I would hesitate to use my bad to pry unless it was essential to survival. I would just expect to loose some tip in the harder, thinner blade.

That tip looked like it had a decent distal taper, and got thinner. Not a good tip for prying at all.

Just great to know that Jerry is good for it.

Super glue and duct tape will fix anything.
 
wow. the tips on the flat ground SFNO sure are thin. probably another reason to get a saber ground SFNO instead.
 
Nothing a hammer and some epoxy resin couldn't solve. Wadya mean ya weren't talkin' to me? When you're in a room full of hammers every problem looks like a nail...
 
Here is a pic of the tips of a fatty sabregrind SFNO (black coating) and a flatgrind SFNO.

The flatgrind SFNO's tip is thin. However I've thrown this baby around and stabbed it many times in some hard wood without any problems. I must admit that because of the thin tip I was a bit more carefull at first but when I realized it could take it all, I used her like all my other (thicker) blades, also the prying part.

So I don't understand fully what Jerry is saying about the knife geometry being the issue:confused:

Maybe I got lucky and I should be more carefull in the future with the flatgrind SFNO?? Or has my knife proven to be stronger and can I continue to use her this heavily?

I know about and appreciate the cool warranty but because I'm overseas I hope I never have to deal with it because of all the hassle (customs, int.shipping, the waiting game etc.)

Holy chit !!!

At least you have the best warranty in the world on your side..

I feel like breaking my .15" green linen Active Duty now...:)
 
Crafft,

That one is so fat I had to take out my SGSFNO and check it against the flat grind I have. And it is a huge difference :eek:... I would have never thought the SG was so much thicker.

Nonsense in my opinion.

There is not a maker on the planet that would tell you his knives, custom or not, are for the safe only.

I pay more for a custom and it performs less than a CG....never...:thumbdn:...not acceptable..

Knives are tools to be used.


Jerry will make this right.

I am in 100% agreement ...

Quoted for the record... Remember that it's unintentional damage that's covered! :p :D
 
That looks like a thin tip for such a long knife. Maybe 1 mm to 2 mm at most? No wonder if it takes a set, especially when you've got a lot of leverage on it due to the long blade and handle. I wouldn't pry with that thin a tip. Perhaps it could be a heat treat issue, but more likely, I think, is that it's just due to the thin tip geometry. I've seen other knives that took a set like that with relatively little lateral pressure - the longer they are, the easier it happens.

Jerry will make it right. :thumbup:
 
fantastic warranty, and what's even more special is the no bullshit way in which it's executed, by the man himself. if only it were contagious, pervasive even...

I think what Jerry meant was that the recent Custom Shop SFNOs were ground thinner than normal for better slicing ability. That particular one seems to have a thinner tip than the CGSFNO and other flat ground satin SFNOs.

That makes sense. I thought the cg(flatgrind)SFNO's and the recent custom shop SFNO's would have the same thin tips:o

Thanks for clearing that up Ban:thumbup:
 
Yeah, yeah. "I broke my SFNO, blah blah blah..."

What a weenie.

Break a Dogfather, then come talk to me.

:D:D:D
 
My custom shop sfno has a super fine tip. I would never pry with it but it is definitely the best slicer of all my busses
 
Just out of curiosity, I wonder if Jerry could enlighten us a little bit about the inspection Busses get to ensure the heat treat is right and stuff like that? I seem to recall Scrapyard doing some kind of liquid penetrant inspection, but I know nothing of how Busse tests blades coming off the grinder to see that they're up to the task. I'm sure there's some kind of protocal, because we've all seen the photos of piles of unfinished blades discarded due to some issue by Jerry. Would be interesting. :thumbup:

LOL The World's Strongest Man competition was just in Charleston WV...we should've taken some infi over and let them try their hand at it:D If infi can stand up to Phil Phister then nothing can touch it:thumbup:
