Great 5.5mm hex drivers

[EverythingIBM]

I recently bought one of these, and I am phenomenally impressed with it. The handle fits the palm well, and it's made of high quality materials in Germany. Also has a decently long shaft (which is the most important part of a good driver when dealing with IBM equipment of that era where they loved using their 5.5mm hex bolts).

Highly recommended.

Sure it's more than the cheap ones you can buy from china, but quality tools really enhance the experience of repairing/cleaning equipment.
