Pinching raspberry canes

My black raspberry canes are growing fast. The new canes should be summer-tipped by removing 2-3 inches from the top. That leaves a 3 feet long cane from the ground. I pinch mine off but hand shears or gloves may be recommended. This promotes growth of side branches and stocky plants that are more ridged. It is necessary to tip the ends of new canes several times during the summer.
