Review: Fantastic quality and assortment of sizes. - Best pocket set of precision bits that I can find online. They fit well in the back pocket and complement the OKNIFE to be able to do various small electronics and appliance repairs on the fly. I constantly am fixing small equipment like this and find myself grabbing these bits out of my pocket rather than getting much more expensive and fancy precision screwdriver sets from my desk. Worth every penny. I have had absolutely no issues with bits stripping or shearing screws either; fantastic quality.
Review: Best Range Tool EVER - This thing is absolutely amazing. I use it as a range tool and let me say its by far the best most compact one I have ever come accross. For the price you will not beat this thing! If you need a firearm tool for sights or just a edc tool get this.
