Thank you for this, Mr. Jan! I always like to learn more about metallurgy.
I guess I knew most of the benefits of fine grain. Is it possible to approximate grain size by performance of a blade?
For instance, if you had two bars (about 1" wide, and 1/8" thick for instance), is it feasible to to bend them, while measuring the strength and flexibility (with a torque wrench for strength, and the ability to measure the the angle of flex), and make any determination about grain size?
The reason I ask is because I don't see other knives that are as strong for their thickness, and also as flexible (being able to bend as far, as many times) as my knives.
I pull every trick in the book (that I'm aware of) to refine the grain of my blades. I've always done this, and I've always tested my blades to destruction to see how they perform, and to see how they break, and what they look like inside.
I certainly know they have changed a lot over the years, but I've never actually had the grain size measured, since I reckon it would be very expensive.
