When I learned to use the nunchaku back in about 1967, we had to make our own chuks and we trained hard and learned one of the important lessons of nunchakujutsu. You have to keep an eye on that weapon at all times in the beginning until you domesticate the weapon, otherwise it will sneak up on you and bite you.
“Nunchaku is like a snake - mistreat it & it will bite” - Soke Hausel
I still have fond memories of training with nunchaku at the University of Utah and later at the University of Wyoming and listening to my students periodically imprint a lifelong memory when swinging the nunchaku and accidentally hitting themselves in the shin, knee, elbow, or other not so friendly spot. There was a distinct sound of wood hitting bone (we did not have foam rubber in those days), followed by "ouch" and a few choice words only an engineer would understand. Why would any karate ka want to miss out on such wonderful memories - we all went through the same lessons.
In closing, leave the boxing gloves at home.
