Buck 110 auto

If you are having problems with your knife, don't try and fix it yourself send it back to Buck and let them fix it. It is most likely a coiled torsion spring. I did not see a flat spring on mine.

Actually i am wanting to to install a faster spring
 
no idear, but once ya knock the pins out and take it apart you'll be able to measure it.
 
Blade4ever--- you just don't go to a hardware store and buy a spring like this. A torsion spring has a free position, a loaded position and afterload position. The tension is also determined by the wire size. I would leave things be. I'd hate to see you drop a bunch of cash on a nice auto and then take it apart and not be able to put it back together. This was all calculated out before the knife was made, they want it to swing out at a speed that it won't flip out of your hand.

If you are really determined locate a spring factory and go there and speak to a supervisor. Ask if they will make a spring .002 bigger wire and coil it to the same position as what you will bring after they tell you they will do it. Then go home and begin to take the knife apart and be sure to capture the spring because it is in a loaded position after getting the spring put it in a baggie and go back to the spring mfg. and give it to the person who ok'd making a new one 2 thousandths bigger wire. put your name and phone number in the baggie and turn it over to the supervisor. This way you have an authorized person to see the the project is followed through. Good Luck!! If you have not guessed I was a tool and diemaker in a spring company for 28 years. I know of what I speak. I did favors of making springs for people that happened to walk in the employee entrance, but that is taking a chance, I was honest and did it for free.

Oh yes one more thing if things screw up you can send it to Buck but they cannot send it back to you some legal reason. Unless that has changed.
 
I’m thinking just give it some time and cycles. Mine wasn’t very fast at first and sometimes didn’t go full open lock. I first washed it with warm soapy water cycling it while submerged. Then rinsed with warm water. Blew it dry with air in a can. Oiled it and after several cycles it now flicks open in a flash every time and locks. Also if you don’t have a firm grip it can dissipate the spring power like a recoil pad on a gun so don’t let it just jump in hand. Hold it firm steadfast.
 
Personally i never alter a knife. Just not my nature. For instance I rarely alter a motorcycle. Some pay a high price for a Harley then spend a ton of coin on performance and bling components. I did that once then realized if i wanted a performance bike i bought one that had it stock.
I enjoy my 112 auto as is bone stock. Wouldn’t change a thing.
I do find those with the ingenuity and know how to do these modifications and upgrades some pretty amazing individuals though.
I do believe in the saying, to each his own.

Have you tried flushing out the pivot? The speed on mine was fine from the factory but slowed down after one specific chore I was doing. I flushed it out with warm water and put a drop of triflo in the pivot and it worked as new.

I can say that they most likely ordered one type of spring to fulfill the order.
One wire size, depending on the type of machine the springs were made on,the diameter and position of the torsional legs can vary in position making the blade swing out a little faster or a little slower. There is always tension on the spring. The heat treat of the spring depending on whether it is music wire or stainless steel, can over time make the spring take a set and become weaker if the heat treat of the parts did not stay in the oven long enough. I was thinking even adding .002 on the wire size will make the spring bind there is only so much room that the spring has to work. The only other thing would be to alter the original spring position by backing off the free position 1/4 of a turn, that is where the spring in the knife come into effect. Not knowing the wire size and how many coils the spring is, the free position is relevant along with the amount of coils. If it has 5 coils the backing off 1/4 should not harm. If the spring has 2 coils, backing off 1/4 would put the spring under too much tension and may distort or break.
