Can i take crochet hooks through Heathrow airport?

ok next week i'm going on a long hall flight to borneo from Heathrow airport, it's 24 hour flight and i don't want to die of boredom. i was wondering if anyone knew if i can take crochet hooks cuz i know knitting needles aren't aloud but crochet hook aren't pointed so i thought it was possible. it says nothing on the website about them. i was wondering if i'd be ok with plastic or wooden. i'm flying by royal brunei airlines, not sure what they would say either. can anyone help?
