The handle is not very egronomic
This depends on the user, while I thought it would be useless before using it, I would now rate it as one of the best handles I have used, and in some respect (security) flat out the best.
the coating will come off exposing the A2 to the elements and unless you do your maintenance it will rust, quickly.
The coating comes off in about 2000-4000 chops based on what I have seen, depending on the type of wood, force of chopping, strength of twisting etc. . Much better than most powder coats but less than HC, and TiN. It can also be redone by Reeve if needed. And when it comes off, it wears slowly and does not chip/flake.
As well, based on what I have seen, most carbon and tool steels tend to take light surface rusting and not deep pitting like Stainless steels, which resist rust only because of the CrO formed on the surface, once this is penetrated the rate at which the rust goes into the material is usually faster than on nonstainless steels.
I have tested this using salt water soaks on INFI, M-INFI, 1095, D2, VG-10 and ATS-34. The Stainless steels and D2 pitted much more estensively than the tool and carbon steels which took a light coating which easily came off with a light scrubbing such as I would do for example to remove pine sap and other gunk.
Ever pick up a black metal knife that has been lying in the 120 degree sun for about 10 minutes, with your bare hand? Ouch. The same for artic enviroments.
While this is true, I have also compared a full bare metal handle to a partial contact one like a full exposed tang (Battle Mistress). Both knives were impossible to use if very cold or very hot. Of course you are reducing the amount of flesh burnt or frozen, but basically unless you have a full encapsulated tang (Allen Blade) I would be very careful in extreme hot/cold enviroments.
As for who I would chose, it would probably be Ed Schott in 3V or Phil Wilson if he would work on such as blade as it is not his usual fare. R. J. Martin is only excluded because of lack of availability for a personal designed custom ground blade. The new "E" Battle Mistress would be another contender depending on the handle which I havn't used. I realize it is not a "custom" in the sense that Busse does not make it himself, but I would prefer that over a lot of "custom" blades in any case and if someone is looking for a true using blade, they should not be concerned about labels but rather function.
