I think that the people who has the riskiest job in the planet belongs to electrical linemen and power line crews. I have observed these people endanger their lives hanging on the ledge or a wire in order to fix it. They’re hanging in a balance in between life and death here. On this type of job you can never fail in your equipment and tools. Every one of these workers should have a reliable electrician tool pouch that won’t fail easily with normal wear and tear. To know about the quality of the bag you can check the manufacturer’s website however, information on them could be one-sided only. The best method I use is entering online forums. Majority of members are helpful to new members and other people who are seeking help. Create a new thread/topic if you can’t find your inquiry and for sure you will have an answer within a day or two.
