You Possessed a Weapon
A knife is fairly obvious. However, other objects, such as a screwdriver, may be considered a dirk or dagger, if it was carried on your person and it was substantially concealed. Other factors, such as where you were at the time when the object was discovered may contribute to your guilt.
A screwdriver belongs to category of simple machines.
A screwdriver is made up of steel which consists of iron. Since Iron is a metal, it is hard and durable that suits the purpose of a screwdriver.
Not Allowed in Carry-On Luggage
Tools, such as hammers, wrenches, crow bars, nails, axes, hatchets, screws, saws, screwdrivers, drills, etc. Sharp objects, such as knives, box cutters, razors (both disposable razors and razor tools), scissors, ice picks, swords, etc.

Firearms, ammunition, and fireworks are prohibited, as are all knives and safety razors (including pocket knives and Swiss Army knives). Straight razors and replacement blades for straight razors are also not allowed. Most tools also cannot be packed in carry-on luggage, as they have the potential to cause harm.
Tools longer than 7 inches (measured from end to end when assembled) are prohibited in carry-on baggage; these items must be packed in your checked bags.
Electronics and lithium batteries
Devices with batteries larger than 160 Wh are never allowed.
Hand tools such as hammers, screwdrivers, plyers and alike will need to be packed securely in your checked baggage.
Power tools must be packed in checked bags, including drills and drill bits. Power tools with installed batteries must be packed in checked bags. Batteries installed in devices must be protected from accidental activation.
If it is for a class, like wood working, ask your teacher first. Otherwise, you are asking for trouble. A screwdriver could be used as a weapon. Any school would see it that way.
If packed in carry-on, they must be less than 4 inches from the pivot point. Any sharp objects in checked bags should be sheathed or securely wrapped to prevent injury to baggage handlers and inspectors. For more prohibited items, please go to the 'What Can I Bring?'

Work tools such as screwdrivers, hammers, etc. are prohibited and also must not be carried in cabin baggage. Yes Providing they do not have a sharp or pointed end, these are permitted. However, where they are very long and are not collapsible, you should consider contacting your airline in advance.
For devices with installed batteries, such as power tools, you can bring them in both checked baggage or carry-on luggage. However, when it comes to spare lithium-ion batteries (those not installed in the tool), they must be packed only in carry-on baggage.
You are allowed to bring a quart-sized bag of liquids, aerosols, gels, creams and pastes through the checkpoint. These are limited to 3.4 ounces (100 milliliters) or less per item. This is also known as the 3-1-1 liquids rule.
Prohibited items in Cabin Baggage:
Weapons such as whips, nan-chakus, baton, or stun gun. Electronic devices which cannot be switched off. Aerosols and liquids* Any other items which are deemed security hazards by local law.
Screwdrivers, drills, and axes are also included in this category. Screwdrivers that are components of eyeglass repair kits, however, will be allowed in sterile areas and in the cabin.
A screwdriver is classified by its tip, which is shaped to fit the driving surfaces (slots, grooves, recesses, etc.) on the corresponding screw head. Proper use requires that the screwdriver's tip engage the head of a screw of the same size and type designation as the screwdriver tip.
There are no formal specifications for hand tools such as electrical/pneumatic screwdrivers. There are specifications on isolated conductors. In this case, the tip of the screwdriver is not considered an isolated conductor, based on the the tip to ground resistance, so this requirement is fine.
Most new, high-end screwdrivers are supplied already magnetised, but sometimes they can lose their magnetism. There are a number of ways you can use magnets to remagnetise a screwdriver, or magnetise one that was never magnetised in the first place.
