Medieval European Daggers and short Swords

[Swordfish]

The shape of the mark is similar to the mark on No. 382 on the scan from Hugo Schneider's book, but rotated 45 degrees. It is brobably inlaid in copper to highlighten it,this is rarely seen but not unusual. I know other medieval items, also South German or Swiss with marks inlaid in latten. One such item I will show later in a chapter about short swords.
It is clearly a cutler's mark and I have no indication that it was added later.

Please note that the book scans are from the chapter 'Dolche und Dolchmesser des Hochmittelalters', not from the chapter 'Schweizerdolche':
