A thick sweater wrapped around the front hand/forearm can be used as a shield to block knife swings/stabs, as can shoes on the hand

Nunchucks are deadly and fast, but if you grabs a trash can, hold it horizontally a hand on both ends, you can use that as a simultaneous shield and battter-style weapon
It's "sloppy" but it works, nunchucks weren't designed to handle that.
