This article was written in 2007 and so isn't exactly hot-off-the-presses, but I have read similar posts on other sites and wanted to know more about how the topic is viewed. I assume that the Sikhs who are cutting are not Khalsa*, so I guess that would leave them to be Sahajdhari? Can the Sahajdhari pick-and-choose what among the 5-Ks they choose to keep?
* However in a recent episode of Weapons Masters on the chakram they had several people who were suppose to be Sikhs who were clean shaven. (You can see the episode on YouTube.) I do not know that they were in fact Khalsa however.

AMRITSAR,
India — The day Jugraj Singh, at age 14, abandoned his turban and had a lifetime’s growth of hair cut off, he collected the tresses from the barbershop floor and packed them into a plastic bag. Then he threw the bag into a river flowing out of Amritsar, the spiritual home of the Sikhs.
