What I am getting at that is if a blade has flex in the foible and not the mezzo or forte, the blade can still be quite a thruster. If the flex is in the mezzo and forte, you have limp noodles.
...........and I'm out.
Believe it or not.

Which is why I imagined the test would involve pushing the point straight into a block of wood and seeing *where* along the blade the displacement off center line occurs. Letting the blade sag under its own weight illustrates the same but without giving a force reading to compare.
More realistic as a representation of thrusting than sticking the tip in a clamp and bending the hilt, too.
Alright, I might as well try to do a test like that next time I review. Others can do the same and hopefully the best method sticks around.

I'll grab that maybe-Deepeeka-cut-and-thrust from my buddy and write a review of it and include the flex number to see where it sits comparative to the others I have.

I think this issue is too complex to apply a single standard metric to. Despite the quality of a given heat treatment, a blade's thickness is going to significantly alter the results of a flex test. There is a limit to how much material can be displaced before taking a set, and that same thickness will also play a role in the heat treatment of a given blade (due to the mass, and the rate at which the temperature can effectively be altered). All else being equal, a thin blade like a lenticular Oakeshott type XIV, will heat and cool at a much quicker and more uniform rate than a particularly thick Oakeshott type XVIIIb with a diamond cross-section.

I really appreciate that this is being discussed, so please forgive the bump if this was on the way to petering out. I really like the ideas perignum Rufus, Adventurer’sBlade, Edelweiss, Zen Maybe along with the scores you envisioned giving, to give an even more thorough accounting of flex that is still not too complex, you could say something like “the blade reaches flex at 12kg (or has a score of 1.2) with max flex exhibited at ‘x’”- and have x be the measurement in cm/inches (going from base towards tip) of where the blade exhibits the height of it’s flex? Height being the mid point between where flex starts and ends, the deepest point of the curve? Or maybe the beginning of it? So the score could be, for example: “Flex Score= 1.2, maxing @ 26 in. of the 34in. blade.” Or somesuch. And I think eventually along with this, people would see that a different set of expectations emerge for different blade types in the flex department. With enough data it would be interesting to see averages for things like Longsword vs Rapier vs. Arming Sword, and even into different subtypes- because of course different flex is warranted between a type XI and a type XV, for instance. I just love the idea of this becoming something we can point to as data, the way distal taper has. It’s definitely a very tricky stat to lock down, but with the amount of educated people in these forums I think we could avoid it becoming too much of a mockery of itself. But like Taper, which is a complex stat that we all still grapple with, despite any misunderstandings about “absolute” expectations, it’s valuable to have that attention on it.
