MBS1 4mm Hex Bit Screwdriver Set, for Opry, D1, U1 Pro Series | 9 PCS Durable S2 Tool Steel Double-Ended Bit Set with Eternal Pencil, T/PH/SL/H sizes, Compatible with 4mm hex drivers

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.

Perfect bit set, great addition to my stash pocket. Would highly recommend for EDC (comes with a graphite pencil too). Great companion for the utility knife.

This multi tool set is a must have. It works with the otacle and with the oknife u1 pro. Have it on a key ring with a carabiner and it helps with glasses and knives and any small screws. It also comes with a pencil bit which you can buy refill bits from amazon or olight directly. Lightweight super durable bits. Small storage footprint and excellent value.

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.

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.

Nice set of bits, I like the flexible lower side to push the bits out, the pencil is an awesome EDC carry for my folding utility knife with the 4mm bit holder

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

✓Good ✓Fast ✓Cheap! Know what you're getting into, all eternal pencils suck but they're a really neat gimmick. You can technically write with it! Bits are holding up to daily dad-stuff so far. Don't be an idiot and they'll do you just fine. (Also if you're buying this for a Cybertool, toss some 4mm magnets and some super glue in your cart and they'll work great! Otherwise they'll fall out. They will comfortably fit in the knife's bit-holders as well!)

特に鉛筆？ビットは書いた文字も消しゴムで消せるので仕事で書き直しが必要な記入時に重宝しています！

Tolles kleines Gadget zum erweitern des Tools. Sinnvolle Bits.

Excellent all good

価格が高い。品質は期待出来るが、鉛筆？のようなものは書いてもほぼ見えないくらい薄くしか書けません。

Super Set zum immer dabei haben. Die Bits halten auch ein bisschen Drehmoment aus und brechen nicht gleich.
