Help requested with identifying some 14th century heraldry

[Lee]

Thank you gentlemen!

cornelistromp - I can confirm that the blade is exactly of the form you have predicted based upon the inscription.

Reichsritter - The beast (and I personally have also interpreted it as a lion) appears to have a pair of cat ears on a bare head (short and pointy ears with an intervening line for the scalp - so five short lines).

I do apologize for the photo quality - I will see what I can do about getting some decent overall and detail photographs.
