Bit braces (the C shaped tools) are also the finest Phillips screwdrivers available, I&#x27;ve found.  The design makes it easy to exert a lot of force to prevent the bit from camming out, and the amount of torque one can generate is astounding.  Braces are measured by the diameter of the rotation; most good ones are in the 8&quot;-10&quot; range, which is probably more appropriate for casual use.  14&quot; and up were generally for driving big augers, and you need every bit of that torque.  I have a 6&quot; one that is cute and small but not actually all that useful due to jaw issues.
