The most convenient design I see is to have enough room to place a PT50B into your impact tester stand under the blade:
- take a baseline sharpness score;
- replace the ATF with the impact bar, placing it straight on the PT50B platform - lower the knife to contact (and for rolling test also apply 500g - 1 kg load);
- return the ATF and take the score.
Such a design makes it salable as an adjunct to your current testers.
Not sure about 65HRC for the impact bar, as I just got half a dozen custom knives from a knifemaker at 63-65HRC to sharpen.
