Question for anyone with Gatco Tri-Seps or Lansky Crock Stick dog bone sharpeners.

Does anyone know the width of the sharpening surface on either of these? I have a Buck Paklite Guthook, to supplement my hunting knife. It occurs to me that normal sharpening stones and systems won't fit in the rectangular "hook". For what it's worth, the hook gap measures about 9mm wide. Thanks,

 
You could also use wet/dry sandpaper, wrapped around the edge of a piece of wood, cut/sized/shaped to match the width of the hook in that knife. Nice thing is, you'd have a wide range of grits to choose from, and could use a longer abrasive surface (up to the length of a sheet of wet/dry, around 11" or so).

That's how I'd do it. :)
 
To expand what OWE said, another alternative is to create sandpaper "files" in various grits using pressure sensitive adhesive (PSA, self-stick sandpaper) on a piece of wood. You could cut/plane a piece of wood to 9mm, then adhere some PSA to that edge and trim it with a utility knife to remove whatever sandpaper is sticking out past the edge of the wood.

If you can't find PSA locally, you can make your substitute with regular sandpaper glued to the wood with spray adhesive (3M #77 spray adhesive perhaps).

Because only one wood surface has abrasive on it, you can sharpen right into the corners without damaging the adjacent face of the hook's square notch.
 
My Lansky crock stick doesn't fit into my Kershaw gut - hook , which looks very similar to your Buck. The Gatco tri-seps I have is even wider . I used a tapered diamond rod.
