This double sheath is for the person that wants to carry with himself some additions to their favourite leatherman tool. Those additions are variable and you can choose yourself what you want to include. Things you could have in the extra pouch could be, bit kits, flashlight, ratchet driver/bit extender, pencil or whatever you choose. The extra pouch is the same size as the main tool, so you can fit in anything that is the size of the tool. And for another mather, you could switch sides for left and right if you want to. They are hand made by myself in sweden. Message me if you have questions about this sheath. This item is made of leather.
