Jan, are you implying we do not center blades in knife jigs before grinding? - we always do.
BTW, the Tormek knife jig SVM-45 centers a 2.1 mm blade, not 2.5 mm as you think.
Anyway, the blade thickness behind the edge matters for accurate calculation, even if using a self-centering jig.
Our software update is not only for the sake of the edge angle accuracy, but for better matching the grinding and honing angles to get a sharper edge.
As you guys can see at the http://knifegrinders.com.au/software_testing.htm the BESS Sharpness Tester PT50 showed 60-80 BES for the 12° and 16° edge honed with the Tormek honing paste at the ground angle. This is an improvement over what we observed in the past for the knife steels used in this testing.
