EdRozen,
BK&T stands for Becker Knife and Tool which is a working line of knives that was recently resurrected by Camillus.
I'd say the only reason your TOPs Steel Eagle doesn't meet the current definition of elite "supertough" knives is because it's made of 1095 steel. This is a very fine high carbon steel, the same that KaBar uses I believe, but it's very common, not expensive and has been around for a long time. I think it's safe to say that, when properly heat treated, there are a significant number of other steels that can outperform it in basically all categories. Thus, it's possible to make a very good knife out of 1095 (and I imagine the TOPs is one). But you've clearly stated that you don't want a very good knife, you want the best, and so, if you are searching for the absolute ne plus ultra in terms of performance, you must look elsewhere.
I'll also point out that in your first post you wanted the "strongest", and in your most recent post you're looking for the "toughest". I'm not trying to be a stickler, but it's important to realize that these are not the same thing. In fact, you have to give up one to get the other. Many steels can be made to excel at one or the other, but it's rare to encounter a steel that excels at both. It's for this reason that we've so strongly recommend looking at the INFI blades of the Busse line and the CPM 3V steel that several custom makers now offer. These truly are "elite" steels which employ alternative manufacturing processes allowing them to achieve abnormally high levels of performance in both categories.
Cliff, if you would be so kind to enlighten us again, are there any steel knives currently produced that can match the toughness of an MK&T Beta Ti blade?
