TK-Tweak - 4mm Precision screwdriver

Sold Out


Product Details

"I need some good marketing words for right here, catchy tag line, etc"

The TK-Tweak provides storage for 2 extra bits under the end cap, so at any given time you can have 3 bits with you. That said, there are no bits included. Charging you for bits you won't use doesn't make sense to me. Too many different types of bits (I suggest Wiha), and everyone will be using this for different tasks I'm sure. Maybe you got this for cell phone repair, working on an RC car, or changing your blade in TUKK ;)

Details: Currently you can only select Copper or Brass accents

Weight: ~ 0.6 oz

Size: ~ 3-3/16" long

Material: Titanium shaft with Brass or Copper 'Grip and End cap', and a Bearing

*NEW UPDATE* New batch of TK-Tweak now fits cheap china bits (They are undersized), also now fits "socket" bits.  I still highly recommend Wiha Bits

**Actual product finish/appearance varies from batch to batch.

Always Tweakin

I use my Tweak everyday, it is always in my go bag and my edc kit!! This is my favorite go to tool for all my electronics projects! The quality is top notch!! Liked it so much I got 3!!!


Great little tweak tool, as a professional electronic engineer this sits in my grab tool bag as an emergency driver.
It's well machined and really fit for purpose.
The only small thing to consider is depth, the bottom grip means it does struggle with some sunken fastener holes, and the only reason I keep it as a backup. I'd love to have it as a replacement as I just love the feel and quality of it.

Tweak away!

This is a great little tool. I wanted to replace my swisskey for a long time but couldn't find a small screwdriver that would work for small to extra small screws. Even the swisskey couldn't do eye glasses screws but could manage the screws to my Evolve skateboard remote. In comes Tweak! I can customize the bits I need for the day with the two storage and one in driver availability but usually just carry two incognito. The build quality is top-notch and even just holding it in the hand is a joy. Great work!

Top Notch

Going to be a returning customer with this type of quality and usefulness, I need a pen bit to go with it and would make a fine writing tool also.
Thanks for making cool stuff !-)


This is a great little screwdriver. I already had a set of Wiha bits and they fit perfectly. This is a nice piece of kit that stays out on my desk for any disassembly or assembly task. The end cap has a bearing with fluid motion and doesn’t wobble. Solid construction and great size.
