All of my sheaths are custom fit pouch type. I hand rub Obenauf's Leather Oil into the sheath seven times in a warm place. This will protect the blade from the elements for a good while. Follow-up care will be the customer's responsibility.
I don't like buttons and snaps and do not expect my customers to put up with them either. All my sheaths are form fitting custom pouches. I have been known to demonstrate these sheaths by turning them upside down and shaking the knife (they stay in) and yet they pop in and out easily.
Here is a run of sheaths on the bench in the early stages of completion.
"Side Rider" custom sheaths.
A few of the ones from before my hallmark. These were a great learning experience and are of great interest to the collector. If you ever find one you suspect is mine please let me know because I miss them and would like more photos.
