Heritage Sheath

I’ve recently picked up the Leatherman Heritage Sheath for my Arc. I was wondering if anyone has any recommended mods, or accessories that would work with it? I understand that because it’s leather it will require some maintenance, I have already conditioned it and waterproofed it with mink oil. I’ve seen some people fit their bit extension with their multi tool and clip flashlights on the side, I’m wondering how that lasted or how reliable the retention is?
