Can you name another manufacturer that makes a thinnly ground integral knife with micarta handles, and a carbon steel convex edge? I can't.
One of your favorite makers, Marbles, is making the sport2001 with a micarta gamegetter handle. The old Sport 99 also would qualify, except that these two knives have brass guards.
The only two makers that I have seen use integral guards are Mcclung and Blade (who worked for Mcclung).
Cliff pointed out that the MEUK was cheaper than the BA3, although the MEUK sold for around $100 in 1095, the market is now almost twice that, if you can find one. Also, the caffery heat treat 52100 steel, etc would add to the price.
The Busse BAIII, with a thin convex edge will outperform many knives including knives with thinner spines. The INFI steel really does allow for a nice thin, yet durable edge. IT excels at wood work. I speak from experience on that statement.
I think Buzz nailed the mark when he wrote that the test of a steel is how it performs on a knife with a thin edge. Having a knife with a superior steel and a thick edge is quite silly. You do not take advantages of strength that a high end steel offers when you grind the edge thick.
If you are selling durability and toughness, I have not seen a steel yet that compares to a simple spring steel like 5160. Jerry once wrote that there was $90 in steel in a BM IIRC, a 5160 knife may have 5 bucks of steel. If you are going to grind thick tough edges, you may as well use the cheaper, tougher steel. If you are not going to utilize the added wear resistance (abbrasion resistance) or strength ( resistance to deformation) than there is no reason to go with a highly alloyed steel.
