I have a carhart pouch I use...to carry my smokes, phone, tape measure and writing instruments (pen, pencil, sharpie, crayon, whatever). I rarely put a tool in the "tool pouch".
To carry the tools for day/job I use a bucket...a simple empty bucket w/no "liner" with a million pockets on it. It's simple, easy to see in and grab stuff out of...and I can also sit on it if the job calls for it (like putting in devices...bucket full of devices, wirenuts, pigtails, etc).
Two tools are in my pants pocket 90% of the time...my pliers and a 10-in-1 screwdriver (both Klien).
The "tool belt" is for my "stuff", the bucket is for tools.
