I think I see where you're coming from, Cliff. A longer, very thin blade. I have trouble imagining anything I would do to my Caly 3.5 that would risk bending or breaking it (aside from the tip if I dropped it on tile ) but thinking of my Roselli Minnow, I suppose it's conceivable... Still feels more like abuse than use but I'm starting to see.Cliff Stamp wrote:The last is one of the common arguments for differential hardening which achieves the same thing in a different manner. Draw the spine and the blade will be much harder to break but easier to damage.
As an example I commonly get fillet knives to sharpen and they almost always have bent/warped blades. One of the main reasons for this is that the steels are very soft 3-5Cr13 class steels with a less than ideal HT which leaves them soft, and gummy (retained austenite and likely ferrite).
If those blades were instead solid S90V at 95% martensite (or similar class steels) then there would be less of them bent but some of them would be broken. In general the ones from the skilled guys would be fine the less skilled guys could break them from sloppy technique.
Thanks brother!
