| If your not going to be using an auto for some time does it make a difference whether it's stored open or closed? thanks |

What kind of knife is it? Sharp and Pointy one.  
I was just asking because your advice is probably wrong!   heh..your funny. Q- How do you recommend storing the automatic knives, opened or closed?
A- When storing the autos for an extended period of time you can keep it in the closed position. Storing it closed will not harm it, however it may weaken the coil spring over time. Please note: The coil spring on the auto’s is covered under our warranty and if it does weaken or break we will replace it at no charge. http://www.onestopknifeshop.com/store/benchmade-faqs.html#a29

| From an engineering perspective, springs are not weakened or worn out by being under load. It is the compression and release cycles that take them to their useful life limit. The only thing you can really do to damage a properly made spring is to compress it shorter than it's minimum design length. In the case of a torsion spring, that would be rotating it more degrees than it's design point. |

Two things:
1. Same as keeping mags loaded. Springs are worn out by cycling, not static compression. Obviously a different type of spring in question here, but same principles apply. 2. If it is an auto, then the spring is going to be under load in both the open and closed position. Store them however you want to. |

This is what I always thought. I've been confused by the recommendations to store open (not just in this thread). I've stored mine closed for almost 10 years now with no issues or any perceivable loss in opening speed/energy (not that I could actually measure it). |
