Do not hit the metal fittings hard in one go, but always hit them in 3 or 4 separate hits.
If you hit it hard
in one go, the metal fittings may not be fastened properly or the fastener may not come out of the fittings.
Please use metal fittings that are appropriate for the thickness of the leather.
If a metal fitting designed for 3 mm thick leather is used on 1 mm thick leather, the metal fitting may become deformed or the fastener may become stuck.
When striking, use a
Round Maul or a Wooden Mallet
, not a Metal Hammer.
Using a Metal Hammer can cause the striking tool to deform or rust.
