Bladerunner

Went to visit a neighbour who recently returned from Oman, where we met up for coffee on the odd occasion as one of my pals knew one of her pals and therefore we all became friends.
As it was beautiful and sunny here in Aberdeenshire today, we went to sit out in her garden with our cups of tea. I was most surprised to see these blades leaning up against the wall. Apparently they belong to her son, but are for sale if anyone is interested. They do look a bit different to the ones that Oscar Pistorius wore to run in the Olympics, but these are for an able bodied person. I wasn't brave enough to try them !
