Therefore, destructive testing, while having some possible academic, theoretical value, are not of much value to the average knife user. Cliff has accumulated a large amount of statistics that are relevant maybe in a science lab, but don't mean that much to the guy taking his knife out on the trail. A proper choice of tools is much more important.
I guess I have a different perspective on destructive testing. One that allows me to draw some conclusions, and ergo some achieve some learning.
Destructive testing is about finding limits. Finding limits with knives made of various materials, at various hardnesses, with various blade grinds, etc, can help one choose materials and dimensions for a high performance blade. And, in case you haven't caught all of Cliff's reviews, aggressive testing can flesh out hype and puffery sometimes... and lord knows there is a lot of that chaff to sort out here on these forums.
How do you suppose aerospace engineers optimize the selection of various materials and components used to build an airliner? More relevantly, how do you suppose a materials engineer optimizes the selection of, say, extruder blades used to cut pellets from a polymer billet in the manufacture of polymer pellets (that end up being used in a huge variety of materials in daily use, e.g., automobile interior materials, PVC pipe, plastic cups and mugs, etc). Do you suppose a Charpy tester would be useful in the design of the spec for materials that will see sudden impact forces/stresses/loading? Suspended walkways? Suspension bridges?
While I'll agree that the average person might only have and/or need a couple of very high performance knives, and plenty of the rest of the knives are typically used within reasonable boundaries, there is some value in understanding appropriate materials, hardnesses, grind profiles/angles/thicknesses to be used in the custom mfg of a high performance knife.
I have learned enough from Cliff and others that I could collaborate with a good custom maker to make a high performance knife that would exceed the performance of others that I currently own, albeit maybe in small ways like handle ergos for my particular hands and preferences (e.g. flared handle butt), but in some big ways like steel, hardness, blade profile. To me that is where the value is in Cliff's testing... I learn, I challenge my previously held ideas, I learn some more, and I end up ahead for my effort, which is pretty light... some reading, and later some field testing.
Tests that subject a knife to reasonable bounds, considering it's design, yield very useful results. I then see no problem with aggressive testing, and/or moderately or completely destructive testing (how many people are willing to do this with their money?) once the basics are covered.
YRMV.
My collection is shrinking in quantity, by design. There are plenty of daily carry knives that see light to moderate use. I'll ultimately boil my collection down to a select few knives that mean something to me and have their places in my own world. That will include a select few hard use knives... some big choppers, some hard abrasion resistant slicers, and others.
