Well then your choice is limited for a French Kate the. By the sound of it that pattern would make a perfect gift.
I understand what you are saying about the Rough Rider as I felt the same. But.....while impatiently waiting for my Case Trapperlock to come back from repair, I bought the Rough Rider version in smooth tobacco bone just to try. I was presently surprised - the only bad part is the back filler has a gap at one end. But for $12 I certainly can't complain.
I see 2 options for you. First is buy the GEC and give it a good cleaning, oil the joint, and give it a coat of wax. I think that would hold it well enough under light use for a few months. Each time you see her you could give it a touch up.
Second - swallow your pride a little like I did and spend the $12 and try a Rough Rider - you just might be pleasantly surprised. Also, I totally understand and agree with you about the country or origin, but the pattern is also what you are buying for that special gift.
