These are a great improvement over the old Peter Lynn handles.  They are made of tubular aluminum and are covered with a veneer of padded foam, providing a smooth, comfy grip.  They are color coded for left and right.  There are stake loops on the bottoms and a loop for a strop attachment on the back of the tops.  The small ones are about 12.5" (32 cm) long and the large ones are 16.5" (42 cm).
