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: Handy Dandy Bits! - Like all the Bits for my OKNIFE Thay are great with my route 66 razor blade knife. Thay aso work with other Items.

### ⭐⭐⭐⭐ Incredibly portable
*by Z***S on May 5, 2026*

The OKNIFE MBS1 4mm hex bits are excellent and incredibly portable. Unfortunately, they aren't compatible with the Klein Tools 32611P Mini Precision Screwdriver, though that’s on Klein Tools rather than OKNIFE. While the OKNIFE bits are a standard 3.9mm, Klein uses a proprietary 3.6mm size.
