When something breaks on a job site, a small tool kit can mean the difference between fixing it, and having to leave the site with equipment not up and running.
Here is the small set of tools that I keep in my workbag ready to go wherever I need them. When working on the job,(in my case IT) these are the pieces I personally find most useful and necessary.

The contents of the pouch includes:
- 1000D Cordura by OwlxWhiskey
- Bit extender
- Bit holder with 9 1/4in Bits
- Precision bits holder with 6 bits
- Wera Bit holder 813
- Punch down tool from Amazon
- Pocket Calipers
- Knipex Cobras 125mm
- Klein Snips
- Bic Lighter
- Gorilla brand Glue Stick

Measuring 5 and 1/2 in by 3 and 3/4 in, made of 1000D Cordura with #8 YKK zippers, this small pouch contains all the tools I need to supplement my everyday carry.
The size of the pouch is actually a very important part of it, and the main reason I felt compelled to make this piece, though there are similar pouches out there. I needed something that would fit perfectly in my back pocket, but have a zipper that remains accessible over the top of the pocket so I can still reach the tools inside. As shown below:

An extra feature included with this pouch is the small, inner flip-out pouch, pictured below. This smaller pouch is sewn into the front of the main pocket and holds 6mm bits for the precision adapter housed in the bit holder. The 6mm bits come in handy when you need to repair electronics such as laptops and smaller components.

In conclusion this is a very valuable addition to my everyday carry items that I take to work, that keeps me from having to lug around a full-size tool bag everywhere I go. Though there are some exclusions, for the majority of jobs this tool kit is enough to get the job done.
