TEAMWILL Set of 4 Steel 304 Springs for Microtech Ultratech OTF UT Series Knives USA

These springs may be different in color and length, but may be better springs than OEM (not sure about consistency of the product going forward, since no longer available at this time). The original springs from the OEM knife manufacturer may or may not be be way too stiff to be reasonable for practical use. These springs solved all my problems with little install effort. The hooks left at the end of the springs were a bit short, but with careful, minor crimping were sufficient. Stretch springs carefully as needed, but mine required no stretching and that could definitely ruin them in the process, so be very careful and only make very minor incremental adjustments as needed. Very much worth it!

I installed this spring on my OTF and it was a little shorter than the original, not by much. Actually made my knife perform better. Long story short, they work. Use my knife everyday. Same spring probably has 2000 plus open and shuts on it.

There were only 2 in my delivery pack. Not 4.

Three of the springs were the same size and one was even smaller. None could work in an ultratech
