I find it interesting that many Busse fans will use the destruction tests on youtube as testament to the Busse knives toughness, yet when a Busse is outperformed by another knife, these tests are no longer valid. When Busse holds up better to abuse than a Strider or Chris Reeve knife the Busse fans won't dismiss the tests as proof of toughness and quality. But here we have a Randall that clearly held up better and there is all sorts of speculation. I have nothing against any particular knife brand, so my comments are not in support of Randall or against Busse, just a neutral observation.
I have scanned through this and can't find a single "Busse fan" saying that the destruction tests aren't valid. I have seen that point of view on this thread, although by people who say the exact same thing every time, Busse or not. But, that said...
This Busse has the "competition cutter" edge geometry on it, which is a very fine edge designed for cutting on soft targets (clean wood with no hidden nails or knots, etc). This is a variation of the standard or "combat" Sarsquatch, and the difference is all in the edge geometry. Busse only started doing this within the last 18 months or so, as many customers had requested a more slice-ready version of some of the knives. My problem with this comparison has a few points:
1) The absolute thinnest possible factory grind on a Busse knife was chosen--a grind that represents less than 5% of Busse products--to compare toughness to another knife
2) No data on how many hits there were with each blade
3) The shot of the Randall's edge is noticeably farther away and less detailed than the shot of the Busse's edge.
Okay, now time for concessions---no, INFI is not magic. It is steel, it grinds like steel, it sharpens like steel. What is exceptional about it is the combination of properties it has--its toughness at very high hardness (a hardness that gives it very good edge holding in abrasive cutting and resistance to blunting-type deformation) combined with its relatively good corrosion resistance, all taken together is fairly unique. Basically, I rate it as a semi-stainless version of 3V, which is another excellent--but not magic--steel. I have chipped INFI, I've chipped 3V, I've chipped L6, and I've seen pictures of chipped S7. The fact that they've chipped doesn't mean that these aren't tough steels. It means that absolutely every steel, rock, bone, piece of glass in the world has a tensile strength based on its properties and the amount of the material present.
It's at this point, again, that I feel the need to bring up that the finest, thinnest (and yes, most fragile) factory edge geometry available was chosen for this comparison of toughness. I'm reminded of a "test" of full size trucks that Car and Driver magazine published two years ago, where one of the three tested had the smallest V8 engine available from the manufacturer, and the other two were their brand powerhouses. The excuse that's always given when this kind of lopsidedness shows up is that, "Well, it's the only one we could get in time for the test." And yet, when the conclusions were drawn at the end of the article, they kept harping on how all of the reviewers felt that Truck A was just very underpowered compared to the competition. Well no shit.
Now, Randall. I think the claims that Randall knives are only for collecting and can't handle rough use are complete BS. Randall makes a damned decent knife. Also, they chose long ago to sacrifice edge holding in activities like skinning in order to gain toughness for field use, both in their steel selections and also in the hardness range they shoot for being in the mid-50s HRC. And yes, I know, somebody whom you'd trust your life to and you
know would never lie to you skinned 700 elephants with his Randall drop point and never sharpened it once. Hasn't been my experience with them. At all. Still, they've gone to war, on safari, and with expeditions for generations now, and their record is proven.
My problem with them is that since W.D. died, the brand largely seems to be resting on its laurels and no longer trying. All of the Randalls I have or have had, have been older ones, and I've never ordered one new. However, of all of my knife knut friends, two have had serious issues with knives they'd ordered in the past five years. The first ordered nickel furniture on his knife and no sawback, and after four years received a knife with brass furniture and with a sawback. No problem--mistakes happen. He contacted them and sent it back, assured that he'd have the correct knife in short order. A couple of weeks go by and he doesn't hear anything, so he calls to verify that they'd received it. Get's a "it's pretty busy here now and you just have to wait your turn" answer. Okay, the tone bugged him a little bit, but he knew the busy claim was accurate so he waited some more. At three months, he called back and asked for an update, and they didn't have record of his knife coming in. So he went down to the post office, got them to print him out a page that showed proof that the box had been signed for, scanned it and emailed it to them, and after about a week received in the mail his replacement knife, which had no sawback but still a brass guard.
The other issue was just this past year. Now, this is a LONG time customer--Jaimie's in his sixties and ordered his first Randall when he was something like fifteen or sixteen. He carried one in Vietnam and has used them hunting and fishing all over Canada and most of the northern US. His expectations (and high opinion) of them are based on his experiences over those years. So, the most recent one he got was a model 14, and he took it deer hunting/camping with him. When cleaning time came, he used it to split the sternum. Now, we're not talking about chopping bone here. This is a slice against an extremely soft and flexible bone that you just pull right through. I've done it several times with a Buck 110. He heard several popping sounds during the pull-through, and when the blade came out he found several huge chunks missing out of the blade. I don't just mean the very edge, these had gone up into the primary grind. When he called them to talk about it, he received a fairly nasty rebuff saying that if he was dumb enough to "chop bone" with his knife then it was abuse and his own fault. He's more the type to avoid confrontations, but after I heard that and saw for myself what damage the knife had taken, I took pictures and emailed them to Randall to say that even if the use were abusive--which it wasn't--the damage seemed excessive and someone might want to take a look at it. Basically the response I got back can be summed up as, "thank you--we know how to make knives."
I took it down to a local machine/tool shop and asked for a hardness test on the C scale. This had to be done on the flat portions of course, but as the 440B knives are not differentially hardened anyway it told me all I need to know. Testing five points along the blade, the hardness ranged from 50-52 HRC. Pretty much the hardness of a hammer or cheap screwdriver. So I got them to print me out the results and gave them to Jaime (the owner) to send back along with his knife, and fired off a copy to Gary Randall asking him if five to seven points below the stated hardness fell under the heading of 'knowing how to make a knife.' In the end, finally, they sent Jaimie a new one. It took like five or six months but they did it. No acknowledgment of the mistake or the apologies for the attitudes presented, but he did get a knife back.
Here's the original (and the little dots along the blade above the primary grind are the hardness testing points). Keep in mind, this was from slicing--not chopping, batoning or any impact of any kind.
Now, my point--yes, believe it or not I have one.

EVERY company that makes anything, knives or cars or bars of soap, will have duds make it through the process. Just a mathematical certainty. But, the way the problem is dealt with says a lot about the company. Bo Randall would have bent over backwards to make these kind of problems right. It was his responsibility to make each knife with his name on it be as good as it could be, not the customer's. But, of course, he's the one that made the company what it was.
I've had occasion to make use of the Busse warranty. It wasn't actually on a Busse but a Swamp Rat with a bit of a HT problem, but the same thing applies all over all of their brands. I emailed Eric Isaacson, and got a reply both from he and Jerry in the same day. When the knife got to them, I got called, had the problem explained to me, and was holding my new knife within the week.
Also, Bo was an innovator. In WW2, 440B stainless was a new and awesome cutlery steel---a stainless steel that could hold an edge!! Incredible!!! Bo was just about the only knifemaker using it, and spent time working with it to maximize its potential as a cutlery steel. You know what else was new then? The new Goodyear all-nylon corded tires! Up to 2.5 times as strong as traditional tires using Rayon!! Hell yeah, baby!!! Often lasted up to ten or even fifteen thousand miles without a blowout!!! What more do you need?...
So, the comparison I'd make from my own experiences would go something like----------
Randall (under W.D.)---dedicated customer service, made purpose-built knives out of a material they'd put time and work into developing to maximize the type of performance they were building for.
Busse (Under Jerry Busse)---dedicated customer service, makes purpose-built knives out of a material they've put time and work into developing to maximize the type of performance they build for.
Randall (after W.D.)---still utilizing the cutting edge of 1940s materials technology in spite of an explosion of options within the industry, with a customer service attitude that seems to be "there are plenty of people who want 'em so just feel lucky you got one."
Busse (after Jerry)---time will tell.
Randall made its name because of its high quality products, and its willingness to stand behind them, and from that grew a desireability that drove up both the price and the prestige of owning one. Busse has done the same. Right now, Busse is standing behind their products. Randall will if you twist their arm and hold their toes to the fire, all the while spouting derisive comments toward you. So, is a new Randall capable of being your battle buddy? Yep. Can you count on them if something goes wrong? Well, I can only speak for myself...
