It'd be tight, Don. Best bet would be to send it in and I'll mold a custom liner for it, unless you feel you can tweak it yourself. The stock liner is an ABS plastic pipe, smashed flat. Works great for the Fallknivens and a few others. Not so great for other ones.
I've yet to see a material that would actually be great for a whole variety of knives. It's the holy grail of plastic!
