This is rather long, and I apologize. I tend to get carried away
when researching conquest era hungarian stuff.
My "Ancient Hungarians" book has this to say about sheaths:
The scabbard was generally made of wood and fitted together from two
parts. An iron or bronze chape was fitted to its lower end. On
more ornate weapons, the chape was of silver or gold. Most chapes
were oval. A unique, buitton-terminalled chape can be seen on the
sabre kept in Vienna that had been a princely insignia of rank. The
semicircular suspension loops were riveted to the scabbard by means
of two metal bands or, more rarely, a fairly wide plaque. The upper
suspension loop also acted as the mount of the scabbard entry the
scabbard and the grip were both covered with fine leather.
I've uploaded a photo of the Vienna sabre - aka Attila's or
Charlemagne's sword. (Which it isn't actually. Very obviously a
conquest era sword.)
Description of sword and scabbard from "Ancient Hungarians"
"The hilt curves towards the blade edge. The iron cross-bar is
covered with a gold plaque decorated with an intricate design of
tendrils and leaves around a four-petalled rosette in the centre.
The grip was riveted to the iron tang. It was first covered with
leather, on to which the gold ring and the pear-shaped pommel were
fitted. These plaques are ornamented with an interlace pattern of
looped tendrils and palmettes. The hilt was repaired in the Middle
Ages. The cross-bar was fitted onto the dismantled grip upside-down
and the damaged grip reinforced with three silver gild bands, two of
which are set with stone inlays. [Note from Khalja - If you want I
can scan a black and white photo of the repair job from another
book - "Art of the Migration Era"]
The 86.4 cm long wooden scabbard was first covered with black
leather. It has two semicircular suspension loops, one at the
scabbard entry, the other halfway down the scabbard. A knob
terminalled chape was then attached to the scabbard. The part of
the scabbard between the chape ring and the lower suspension loop
was covered with a plain gold plaque whose edges were riveted to a
silver plaque on the reverse. The front side of the suspension
loops and both sides of the chape are decorated with a pattern of
looped double scrolls and palmettes. The suspension loops are
bordered with a spiralling tendril. The grip and the scabbard are
decorated with a pattern of looped tendrils executed in repousse and
set against a background of tiny punched circles."
Another idea for scabbard decoration if you were interested in
leather carving, is from a conquest era saddle. I've uploaded a
drawing from "Art of the Migration Era" here:
Sabretaches and belt ends can also be sources of design inspiration.
I hope this is helpful. I have photos of several other sabres with
keen metal bits, so let me know if you'd like to see them. Also
lots of stuff on different sabretache plates and belt designs.
