General:
I doubt wood will damage a Talonite blade. It cannot be that weak? Can it?
I have broken a fair share of blades simply chopping wood. I would rate it as one of the toughest things a blade can be asked to do, depending on the swing technique, the power of the user and the type of wood.
As an example, I have used an Ontario machete to dig many holes, chop up sod, cut through a concrete weight (20 lbs, if anyone cares), chop though mild steel rods, etc., all with little or no harm to the blade. Some minor flattening and rolling, but nothing serious. The same blade (two of them actually) broke apart easily limbing out some hardwood trees.
I had a Talonite blade some time ago, currently it is out on loan, things that I could do very easily with steel blades, dig a hole through a 2x4 for example, I had to be very careful with when using the Talonite one as yes it is very weak. Its tensile strength is about 60% for example of Missions A2 which is actually on the soft side at around 56 RC.
I currently have on loan a forged Talonite blade (owned by Will York), and the edge rolls quite readily during chopping. It doesn't suffer gross damage, but this would be very odd indeed because it is so light (300 g) and therefore the impact energies are far too low.
One thing to note is that the Cobalt alloys like Stellite and Talonite have a significant advantage because of their ductility and high wear resistance especially against metals as they have a high resistance to galling. You should include some work of this kind to show the advantages they have over steels.
One other thing is of course the high resistance to corrosion. For example do say a 24 hour soak in salt water and repeat a cutting test to show how the Talonite will be uneffected but the steel alloys will all suffer significant edge loss due to fracture (rust weakining) very quickly. Many stainless blade steels like ATS-34, VG-10 etc., do not handle this well at all.
