I just picked up an 897UH. The knife is in excellent condition except for one thing. The spey and sheepsfoot blades fold incorrectly. The sheepsfoot should fold between the clip and spey, but the spey folds to the center because they aren't correctly bent.

I'd like to bend the blades so that they fold correctly, but I don't want to loosen the pivots due to excessive lateral pressure. What is the best way to go about this, and how much pressure can I safely apply?
 
Thats easy, you just clamp the blade down in a vise, grab the handle and pull very gently until the blade breaks. Then go buy a new knife.
Thanks Rick

Rick, I can only hope that one day, I can offer you the same level of NON ASSISTANCE.
 
Woof! Well, you could just hit it with an oxyacetelyne torch too, but here is how I do it.

I open the misaligned blade (determined by carefully opening and closing all blades in all combinations), then when the blade that needs crinking is selected, and the amount of bend is estimated, I insert the blade into a wooden desk drawer just to the tang, and gently bounce the knife a few degrees down, check the crink, and continue to bend gently until the proper crink is achieved and all the blades park properly without hitting each other or the liners.

It usually doesn't take as much of an adjustment as you might imagine, and this is a good, simple repair technique that all owners of folders should learn. Done slowly and correctly, it doesn't weaken the blade, and the wood prevents scratching up a blade. I have to do this weekly to my EDC 897UH that I use in my construction work, and I am yet to break a blade. Just remember to not try to bend it all at once. Soon, you'll be crinking like a pro. Just don't crink and drive. Or in my case, crink and dive.

It's called cutlering a blade. Second time today I am recommending this book: 'The complete guide to Pocket knife repair' by Ben Kelley, Jr.

I don't have an anvil like the one pictured; I use a section of railroad track.

The tang is annealed to allow it to be crinked. Just make sure the cuttler's hammer is made of a soft material such as brass.
 
I've realigned some blades by gripping the blade near the handle with a pair of vise grips and with another pair slightly bending where the first grips are. I put cardboard between the jaws of both tools so I don't scratch the blade too badly. I think this would be similar to the way described in the picture except you're using visegrips instead of a hammer and vise! Just an idea!
