This is my favorite screwdriver set. These are made by Chapman MFG (http://www.chapmanmfg.com/), 100% in the USA. They are designed for precision work and are incredibly durable. I purchased this particular set for gunsmithing, but I use it all the time for many other things.
Their design gives you a wide range of positioning and torque-control choices. When working with precision parts, valuable items, or other times when you don't want to strip or bugger a fastener, these are the right tool for the job.
Truly the Cadillac of this sort of tool -- and reasonably-priced. The set in this video currently lists for US$37.00 on Amazon. Check them out.
[NB: I have no relationship with Chapman MFG, their distributors, or affiliates. I just love this kit and want to share my enthusiasm with others. Have fun!]
