You can always count on wisdom to significantly reduce the amount of complication in-experienced determination often teaches us craftsmen. Thanks for posting this Doc.
I have used leather on my kydex to make them ambidextrous and for mounting for quite a while now.
The knife on the left is a dagger style kydex with an ambi belt loop. Pretty simple. The complicated knife on the right is the same sheath with a high ride kydex ambi belt loop that can also be worn veritical if so desired. A simple square piece of leather would have accomplished the same thing. With your blessing, you will probably see me pirate your wisdom in the future.
