I had a patch knife that fit (somewhat) into the incorporated sheath on my Graybear bag. The problem was that the handle, made from an antler time was too long, and hit on things. I decided on a hammer finished blade, drilled for pin nominated scales. I used dyed bamboo for the scales, but a cursory look at the scales pass for mahogany. As you can see, the knife is a good fit, and a lot handier. Thanks for looking.
