Judging the performance of Mad Dog knives by some other knife you happen to have that's also made of O1 will give a wildly wrong impression. MD doesn't temper the edge at all; it's file hard. That's not going to perform at all like a tempered edge even though it happens to be made of the same alloy. Try filing that tempered O1 knife ... or cutting a file with it....
Seems to me if I had been making hundreds of knives every year for years, advertising them as the toughest knives bar none, and only six of them failed I wouldn't balk at replacing all six of them even if I thought five of them had been abused, or refunding a customer's money if he broke two of them. Why should I look for an excuse not to? Would replacing six knives drive me into bankruptcy? That whole issue has been discussed enough anyway IMHO -- at least I've said everything I have to say about it, and I suspect everybody else has too -- not that it's been resolved, but that there's nothing more to say about it and no point in repeating it all.... The information that MD says he's had only six returns (and replaced only one of the six) is new, though.
I think a Mad Dog knife would cut 1" manila 2,000 times and still shave. What we're looking for, though, is a knife that will both hold its edge and be tough. I don't think an INFI Busse will surpass an MDK in edge-holding, but it might surpass it in toughness, especially edge toughness. That will have to be investigated.
Somebody said INFI heat treatment is "pretty straight forward, if you have the right equipment." That is NOT equivalent to saying it's "nothing special." It only means it's not difficult to do if you have the right equipment -- possibly relevant to cost, if that "right equipment" isn't terribly expensive, but not relevant to results.
There seem to be a number of people on these forums who think they can look at a list of ingredients of an alloy and determine from that how it will perform. Nobody can do that. If it were that simple we wouldn't have to spend millions of dollars every year developing new steels -- developing a new steel would be just a matter of looking over a list of properties different ingredients give and writing down what ingredients you want in what proportions and ordering a million dollars worth or however much you need -- no experimentation would be needed and industry would save millions annually in research and development costs. Seriously, if you can do that you should be as rich as Bill Gates -- there is a tremendous demand for your talents.
