Katzbalger found at excavation and restored.

I thought I had seen something similar:

McNab, C. (Editor) (2010). Swords: A Visual History. London, Dorling Kindersley Limited.

Horrid book if you're looking for information, but not a bad place to find examples. Pages 150-154 are useful to you. I'll upload reduced images on here per forum rules, and imgur link to the full res versions of the scans. Apologies for doing it in parts; my scanner isn't large enough to do the entire two page spreads.

Both are German, dated 1662. A bit late for your date range, but the associated toolkit looks very, very similar. Perhaps an earlier occurrence of the same purpose?

Imgur links (should be sufficiently high-res to read what text there is):
