Question 1

What I meant is that this statement doesn't seem to make sense: Product description Use this screwdriver without the inserts as a propeller driver?

Accepted Answer

You are correct, the statement does not make sense. Security Engineering has submitted a description for this product but Amazon has not accepted it: Pittsburgh 4 in 1 Screwdriver Set with four tip sizes: #1, #2 Phillips and 3/16", 1/4" slotted blade. Bits are constructed of precision machined, heat-treated and hardened chrome vanadium steel. The shank is constructed of bright chrome-plated steel. The handle is constructed of blue plastic with grey trim. Bits fit into shank at each end and shank slides into handle for storage of three not in use. Shank has a flange for torsion torque and a ball bearing retainer to hold shank inside handle.

Or this: This versatile screwdriver has double-ended bits in four sizes. This 4-in-1 screwdriver has a soft-grip TPR handle for comfort and control.

Question 2

What is the length of the blade not including the handle?

Accepted Answer

The handle is 4", the shank is 4 1/2" one bit is 1 1/2" and the other is 3 1/2"

Question 3

How do you keep the steel Shank from just falling out?

Accepted Answer

There are what looks like 2 small ball bearings that spring back and forth so when you push the steel piece into place the bearings put pressure in the unit that keeps it from falling out.

Question 4

Are the bits 1/4 '' ?

Accepted Answer

Yes, there is one flat 1/4" blade.  There are also Phillips #1, Phillips #2 and 3/16" flat blades.  The blades conveniently store in reversible shaft.
