Those "Older" sheaths fit a multitude of knives.

For instance, the long one fits the BWM so it will also fit the Dog Father.

The shorter one will fit the Scrapper 6 (S6) AND the BGASH1 and so it will also fit the TRASH1.

Those are respectively 10.5 and 6.5 inch blades.

Hope that helps. Oh the fit on the ASH and S6 isn't perfect of course, but WILL work.
