These kits were used throughout the medieval period by cordwainers, leather workers and in some cases. Unfortunately, these were more mundane/utilitarian items that came in all shapes, sizes, and configurations and as such there was no standard.
A basic kit would include:
An awl
Boar Bristles
Bee's Wax
Coad (a mixture of bee's wax and pitch)
A sharp knife
Un-waxed linen thread
Leather
Oil (neets foot)
hide glue (home made)
The contents of the kit listed above.
A mallet
A home-made gauge for making the incised lines
A commercially produced Stamp appropriate to the medieval period.
Parts were cut out of leather with a sharp knife. The parts include:
Outer Tube
Inner Tube
Top cap
Bottom cap
The inner tube was stitched using a flesh edge stitch. The bottom cap was stitched to the inner tube. The outer tube was stitched with a flesh edge stitch and top cap was sewn to the outer tube. The inner tube was placed into the outer tube with hide glue. The outer tube was then cut to create a cap.
A mandrel was placed into the outer tube and the incising was completed in a diamond pattern. A mallet and stamp were used to create the fleur-de-lis shapes within each diamond.
The entire project was coated in neets foot oil and the project was placed in the sun to tan naturally.
