I agree Herman, the knife itself looks period, but there have been examples of re-etches, like SA mottos ground off and replaced with SS mottos. Most HJ's with mottos have stamped maker marks. Why? I surmise the motto was too big to stamp. So why not just etch the Makers Marks at the same time as the Blut und Ehre etch? I would guess because a stamped makers mark is more durable, and more precise than an etched one? On the other hand, the etched Rohm inscriptions on SA/SS blades were hard to remove based on some of the grinding I've seen!
