They are smaller than i expected, but seem to be built sturdy. The handles are a tiny bit uncomfortable. They aren't super high quality but they work well.

The handles have the classic screw driver feel and are molded tightly to the shafts. The tips are black anodized and are precision formed so they fit snugly into the tamper-proof torx screws. Non-magnetic but easy to magnetize if needed.

The tip of this screwdriver is just very tiny and not hardened in the slightest. They seem to be made of too soft an alloy. Very cheaply made.

The dimensions of the product say 8x1x4 inches. There are no flutes on the shaft where it is cast into the handle, so there is practically no torque transmitted before the shaft slips. On just the 4th screw the t10 became stripped.
