It will be interesting to see what this turns out to be. I like it.

The work on the blade seems real and period to me. Not the usual overdone stuff that fakers seem to love. No flaming swastikas or SS runes or Nazi banners or similar. Certainly not done professionally by a jeweler or master engraver, but then, this is a teenager's knife, not a serious presentation piece. Maybe his father or uncle was a metalworker or something similar. The 'crossgrain" is really just scratches ... but that seems over the artwork so maybe a later cleanup by an uninformed amateur.
