Appreciate your taking time to explain - I must have had a slippage of brain cogs yesterday.
The knife edge is to be positioned at the diameter of the semicircle, and since we use the semicircle the scale itself does not require calibration as in case of a straight scale.
CATRA's Hobbigoni laser protractor design limits blade width to 42 mm, while yours can be used to check edge angle on wider blades.
