Knives are not toys and treating them as such will cause damage. 

Automatic Switchblade Knives are not designed to open and close repeatedly over and over for no reason at all.

They are meant to open, then to use, and then finally to close. 

It is a tool and abusing them will cause stress on springs and cause them to heat up and break if stressed past their designs. 

If you feel the need to open and close things use a door not a knife.

Knives with springs will end up breaking with such childish behavior. 

It is a problem and is commonly referred to as CLICK THERAPY that you have to open and close things repeatedly till you break things. 

If you suffer from this disorder do not order anything and purchase a buzzer or bell instead. 

The only exception is the Rat Worx MRX models, these you can be as manic as you want with, so if you suffer from this disorder then this is the only product that has ever been made to enable your crazy behavior.

You have determined you have CLICK THERAPY as a problem and you have already damaged your knife:

Well that happens with most with Stilettos, you have probably down this without oiling things, which is another no brain idiot notion that you should have learned in school and from your parents that you don't mistreat things that have moving parts.  You can heat the spring up and it will loose tension and break.  You first should stop the behavioral problem, then oil the knife, and last if it is a SEX PIN model you can remove the spring and bend it and put more tension to the curve to allow faster opening, go on the forum and ask for help if you have no clue, which if you have poorly behaved you most likely are needing an education.

Next, OTF knives, that is the Out The Front models, man, these are such a problem this is the reason why so many knife companies put tamper proof screws on things.  They are such temperamental knives to begin with.  So you have rapid fired your knife while sitting in your arm chair watching MacGyver and thinking you are some sort of special forces guru, well that is the farthest from the truth, you decided to be an idiot and damaged things.  Springs heat up, they stretch and the knife was not designed for such nonsense behavior.  So you, again you need to oil the knife, but with OTF knives that means using ZIPPO lighter fluid or something very mild.  Now if you are the mall ninja regect and are a cheap ass and bought the cheapest shit OTF possible then screw it use WD40, but that is not doing it right for sure.  If you are a dumbass and used oil you should not have then flush the knife with rubbing alcohol.  If this still does not allow the knife to lock open then you need to shorten the spring because you ahve stretched it out so much or sand the base of the blade so it is shorter, you can go on the forum to see how this is done.  The ultimate goal is not to behave this way because it damages things and if your head wasn't so far up your ass and you had some common sense you would have known this, but we don't live in an America like that, this is MERICA damn it and I am always right and I do what I want and bitch and cry to everyone else and blame them for how stupid I am.  Get real, own up to your own ignorance and get educated, better yourself and start acting like an adult for once and take some responsibiltity.

Knives are tools that are indispensable companions in our daily living and they also are investments. These reasons are why they should be cared for properly. Well-maintained knives will perform better, last longer, and provide the owner years and years of satisfaction.  Do not use the cutting blade as a can opener, chisel, pry bar, screwdriver or for any heavy work for which your knife was not designed. Also, don't use the back of your knife as a hammer. It may break the springs, handles or pins.
