I have Boron accumulated on two types of cores: tunsten wire and carbon.

Interestingly, I've found that I need to use two different methods to "cut" them.

The tunsten core type likes to be bent until it snaps. Squeezing it with pliers does nothing. (If you have to get a boron splinter, this is probably the kind you want. It holds together and comes out cleanly. It also always surprises me how long the splinter ends up being - kind of scary)

The carbon core type likes to be crushed with pliers. Bending it until it snaps causes it to shatter in several places, always including somewhere you didn't want it to break. (Maybe this is the kind of Boron splinter people have had trouble with, dunno)
