in my current position as security supervisor at an secret airport somewhere in britain, i can tell you that if i came across these items i would allow the first three to travel. i'm unsure what the fourth item actually is, so without seeing it i can't say....
knitting needles have been allowed for some time as have other previously 'banned' items as DoT have updated their list...... although it must be said that no specific list is set in stone, and therefore could easily be reversed!! but at the end of the day, it could even go down to the individual that opens your bag!!
hope this is of help!!
