UPDATE - I got an email from the company saying that the OD of the insert is 0.112 inch. The diameter of the hole in the SERE is 0.089. So I have to decide if I want to take it to a machine shop and permanently alter the knife or keep it the way it is. I looked on eBay and they are in the $200 range.

I do have a drill press, but I have no experience with VG-10 stainless.
