Kick stand for a motor bike perhaps?
Thanks I have tried to find a picture of the piece you are describing but no luck yet :-)
I posted this item as well on another site and someone said it might be part of climbing tools ( climbing telephone poles and trees )
I hope I will get a positive ID for this object :-)
Heres an idea, can some one with the relevant software, download the photo, take the left half and reverse it onto the right, I cant help but think its some sort of spring suspension abit like leaf springs. How srong / large is it?
