So the graflex shop blade holder uses 3 holes. These 3 holes are further apart than the MHS discs, not to mention many of the MHS discs only have 2 holes. Why deviate from the 3 hole design? Why have different disc sizes and hole sizes to complicate things when everything can be based on the appropriate sized chassis to use in a graflex, instead of some smaller design to be used in some hilt with a smaller ID?
