I have just made a pattern for a piggyback sheath that will have the big game hunter in the main sheath with a field scalpel in the piggy back. It will have a set of chicago screws to fix a strap that will go through the belt loop of the field scalpel sheath and round the main sheath so that it can be taken off and used as a single sheath in its own right. I will get one put together together with the two knives next week to show here. This will be a first of this concept for me and I want to offer one that is not as bulky as some I have seen
