Hi Centurian- Since you mentioned the liner I assume you're talking about the manual version, so I guess my reply won't really help you.
Just for the record though I have owned several of the automatic versions and it was a nice knife, very light and solid lock up. The handle also felt quite nice in the hand, but I have seen pictures of the manual and you're right in that the liner looks paper thin, well in the photo's anyway, but I have never handled the manual version.
Donald.
