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.

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

Awesome variety of different pets pretty cool the container that they come in as nice. It’s a great holder very lightweight useful for my small screwdrivers.

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.

Excellent little razor knife.

✓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!)

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

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.

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.
