Wolf Wind Leatherworks has introduced a new adustable multi-tool pouch. As you can see, it’s made from leather and includes a strap and buckle to accommodate different sized tools.
Internal dimension:
Length x Width – 4 x 2 cm (1.57” x 0.78”) with an adjustable height from 8.5 cm (3.35”) minimum to 13.5 cm (5.31”) maximum
However, they’ll build you one to fit your specific tool.
