This is both of the wrench / tools for use on Ekornes Stressless chairs. The large one is used for the side knobs which are often tighter (also known as tilt control knobs) as seen in pics #9-11. The smaller one is used for all other screws that have the star shaped head as seen in pics #6-8. Some of the other items that use the smaller wrench are the star (torx) screws for the older ottomans, the swing table and computer table screws as well as all other accessories that have the star shaped (torx) heads. If it is a hex head screw, those are from the earlier chairs and these wrenches will not work. They are made of hardened chrome oxide steel. 

I have many other Stressless parts, please let me know what you're looking for and I'll let you know if I have it. Pictures are very helpful if possible.
