OKNIFE MBS1 4mm Hex Bit Screwdriver Set, 9 PCS Durable S2 Tool Steel Double-Ended Bit Set with Eternal Pencil, Ideal for Opry, D1, U1 Pro Series and Other 4mm Hex Nut Drivers

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.

This is exactly what I wanted to add to my edc! Quality bits that are easily carried.

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.

Omg!! This little bit set is amazing. And it works with the HOTO mini screwdriver even the pencil. I can decide if I keep the whole sleeve in my EDC or just run that bit set in the HOTO. Again this is very nice. The bits look and feel look great. Good quality at a good price.

A simple, compact set of bits for Oknife box cutter tool with driver. It works as you would expect. I have no complaints.

Great addition to my oknife screw drivers and multitools.

I have limited room iny tool bag. These solved that issue.

If you are a EDC fan this would be a great idea for a carry item for everyone every day, because they fit so many different styles of knives and EDC items. I’m sure there is some other great examples you can use them for but for now I’m drawing a blank.

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.
