Nice ones! I just scored another Le Grelot from Ebay France today that has a thumb notch like those seen on the MK31's (thumb notch with that little spike thing next to it on the tang next to the shoulder).
I really want to get a TI Le Grelot to compare, but when I know I can get 3-4 vintage LE Grelot's for the price of the new TI one it is hard to justify. Someday though....
