Amazing! 04/17/2026

The new spring was significantly lighter than the original and the smoother ceramic ball for the lock has been a game changer!

Significant improvement to the function of the knife!
Easy to install.
Now I have 2 very fidget friendly Manix 2 knives!
I highly recommend this kit.

Good, but not for me 02/09/2026

The spring is too light for me. The blade does not have enough tension in the closed position. I did like how easy it was to operate the ball cage but didn’t like the blade tension when closed. I have the Manix 2 Salt and that already comes with a ceramic ball so I could not use that either. The quality on this is good and if you are looking for a real easy open and a lot easier pull on the ball cage this is perfect for you.

Essential Upgrade 11/30/2025

This kit is excellent. The lighter spring allows for easier flick openings. Disengaging the lock is also much smoother; while I had to grab both sides of the cage before, I can now pull it back with either the thumb or the finger only. Installation is a breeze with a good Torx driver. If you are frustrated by the action of your new Manix2, give this inexpensive kit a try first. It makes a world of difference.

The light spring kit works. My manix 2 & dodo are much easier to deploy now. My thumb and finger pads are thanking me.

Awesome as always 07/16/2025

This is the sixth set I’ve installed, always consistent and smooth. Excellent quality and so far has survived a lot of use and fidgeting.

The spring and bearing worked exactly like I'd hoped it would. My Manix is perfect now.
