Good bit driver
Even though I have a small hand this tucks well into my palm. Bought Wiha micro bits to use with it which work well and are secure. Bought a second as a gift. One has some rough edges and some of the black if missing in a few spots so slight finish issues.

Nice tool, but I still like the brass one better
I got this Big Boy Driver after using the brass version for a while. This one is thicker and made of aluminum, so it feels lighter in the hand. The grip is comfortable and the build quality is good — definitely a solid piece of gear.That said, the spinner on the end doesn’t turn quite as smooth as the brass one. It works fine, just not as silky. Overall, still a really nice driver, just personally I prefer the feel and balance of the brass version.

An absolute bargain
First, I’d like to say that I’ve seen many screwdrivers like this however they’re always much more expensive and usually custom pieces. For the price that CRKT is asking on this I believe it is a phenomenal deal. I use it as my dedicated workbench screwdriver. The ball bearing that it has in the end is buttery smooth. 10/10.
