Mr. KG uttered, "Interesting to see that of all only the lower-ish end cheap 420HC steel holds a working edge after 2 series of rolling."
I wish all the knives had been sharpened to the same bevel angle as that would remove one variable that my effect degradation especially in Series 2.
The two Gerber Center Drives 420HC blades that showed the least Series 2 degradation were @ 20° dps., but one of the worst performers was the Gerber Sharkbelly 420HC @ 24° dps. Almost the same bevel angle.
The hardest blades, Hultafors and Morakniv also had the most acute bevel angles @ 10 dps and 13 dps respectively almost half that of some of the others.
Intuitively it would seem that a less acute bevel would perform better in Series 2 as the edge would thicken more quickly.
That said, the EOU tests indicate that for most intents and purposes there is not a significant enough performance variation between HRC 50 and HRC 62 to really worry about. Did the EOU tests test for bevel angle? At the moment I don’t recall.
Mr. Subwoofer, I like the way you presented your data.
