Q. What items are prohibited beyond the passenger screening checkpoint?
A. The FAA prohibits airlines from allowing dangerous or deadly items through the passenger screening checkpoint. Because of the subjective description of dangerous or deadly items, it is the airline's responsibility to determine what they will allow. Most airlines will prohibit items such as scissors, trade tools, and items resembling firearms.
The following are prohibited from being carried beyond the checkpoint:
Knives of any length, composition or description
Cutting instruments of any composition or description, including carpet and box cutters, (and spare blades)
Any device with a folding or retractable blade
Ice picks
Straight razors
Metal scissors
Metal nail files
Corkscrews
Baseball bats
Golf clubs
Ski poles
Hockey sticks
Items which may be transported:
Walking canes
Umbrellas
Nail clippers
Safety razors
Syringes (with documentation of medical need)
Tweezers and eye lash curlers.
So you should be OK with what you want to take. However, remember less is more as there are two chances each way that you may have to have your carry on baggage hand searched (going through checkpoint and before boarding the plane).
