Which screwdriver has a similar tip shape to the Frearson screwdriver?

The Phillips screwdriver is the correct choice because its tip is designed with a cross shape, which allows for better engagement with the screws it is meant to turn. This design provides increased grip compared to a flathead screwdriver. The Frearson screwdriver also shares a similar cross design but features a pointed tip for a tighter fit in the screw slot, enabling greater torque and less slipping.

The Phillips design was created to allow for self-centering and minimizing the risk of cam-out, which is when the screwdriver slips out of the screw head during turning. This is beneficial when working in automotive technology where precise fastening is important. The pointed tip of the Phillips allows it to have a similar functional advantage to the Frearson, making it easier to drive screws efficiently in various applications.

While other options like the flathead, Torx, and Allen have unique designs suited for specific screw types, they do not share the cross-shaped tip characteristic with the Frearson screwdriver. Flathead screwdrivers have a single flat blade, Torx features a star pattern, and Allen screwdrivers have a hexagonal shape, each intended for their respective screw styles. Thus, the Phillips screwdriver is the closest match in terms of tip shape and operational function.
