These are two very sought after pieces.
The large one is a Solingen Germany Wilcat in the tough to get 13" version with the 9" blade. Had never been sharpened since I had it till the other day I had it professionally sharpened and it's a force to be reckoning with at 14 degrees.
The small one I can't even find another one like it and awesome. Read the markings on the sheath. All are in German. I attached it to the bigger one with sinew as to not damage either sheath. These are for a serious collector since they are not your run of the mill.
Both for $225
