Welcome Home...THANK YOU FOR BEING A PART OF OUR COMMUNITY

Folks,

 

I must say I am really impressed with the opening speed of the Kershaw Breakout 7000.

 

This thing is lightning fast! It is a top button lock with a coil spring. In my experience I have not been a big fan of top button coil spring openers, because they were not as fast as leaf spring opening automatic knives and they lacked said opening authority.

 

The only thing I didn't like about the Kershaw was the "rough grindy feeling" when I pushed the release button.

 

Ok, so, I had to find out what made this thing so special so I took it apart.

 

I discovered it had a different coil spring than I was used to seeing, it was flat and had 6 windings.

 

While I had it apart, I polished the release button and the blade where the button made contact.

 

After reasembly, there was no more rough grinding feeling on opening, it was smooth as silk and still fast as ever.

Hey Daniel,

You clever devil, you! Now that's what this Group is all about!

Thanks for sharing!

Nice job Dan !!!
.. unique spring.
Thanks guys! here is a closer look at the spring. I wonder where these can be purchased....

I have never seen a spring like that Daniel, but that is a great look inside a Kershaw!

http://www.newcombspring.com/torsionsprings.html .. these guys could do it .. but one off pricing would probably be prohibitive.

I'd just duplicate the existing matl & coil dimensions if you want to twist your own .. here's a quick down & dirty for twisting springs .. http://home.earthlink.net/~bazillion/types.html

I checked McMaster Carr .. no luck .. did a google search for "flat wire torsion spring" & found the above info.  It's an off the shelf for somebody .. I'll keep an eye out !!!

.. these folks are really close but the cross section looks square .. they "advertise" replacements for Kershaw ..

The spring you show .. that cross section wound the way it is .. more torque than round or sq ..


 

Great inside view of the mechanism and spring! Thanks for posting!
