I was thinking, why didn't they just make the Merkur HD as a three piece razor like the Merkur "classic"? They could make it identical like the classic, but do away with the knob that twists at the bottom of the handle and get rid of the riveted head and make it a separate piece. Then they wouldn't have to make that long threaded post that goes halfway down the handle. Just use the same head, top and bottom as the classic, the only difference is, the fatter handle, keep the handle the same, just make it a one piece handle like the classic. I frankly don't see the point of riveting the head onto the handle or having that TTO to release the top razor head assembly. By riveting the bottom head to the handle, just creates another step in manufacturing. Just make it a 3 piece, the HD would use the identical head assembly as the classic, 2 pieces with the same, shorter threaded post the classic uses. The fatter handle would be the same minus the turning knob, with no bottom razor head fixed to the handle.
