Did you read my post at all?
I found hollow grinds did have a tendency to roll, but even then it can be held in check.
Broad flat grind blades
never roll, even with a round handle.
Hollow handles transfer quite a bit more force than other handles, since they are wider: Unlike form-fitting handles, they strain the stretchable web of skin you have between your thumb and forefinger, which makes for heavier strikes: I did not do a side by side specifically to demonstrate this, but here you can see two knives with identical blades and the same number of hits, and the difference is obvious... They are my Model 14 and a Model 18: One has a form-fitting micarta handle, the other a tube handle: Despite near identical blades, you can see that for the same number of hits the difference in performance is quite noticeable: In reality, I can tell you from handling them it was not even close, the full tang micarta handle being absolutely horrible, with the worst chopping performance of any knife I have ever owned...:
I think I have
daggers that chop better than the Model 14 did... And it was beautifully sharp... The handle fitted my hand perfectly, and that made me realize such things are an illusion under hard use...
As for high end hollow handles being structurally compromised, I have long ago challenged anyone to produce a picture posted anywhere showing a broken tang among any of the high end models, and so far no one has posted a pic of even
one... I found one Aitor, and one old article by Bill Bagwell about an early Buckmaster, which knife model subsequently got an annealed tang, as most of the custom ones have... Martin Knives state outright they have never had a failure, and so can most top makers.
