Go to http://www.youtube.com/watch?v=QInszVD9WpE&feature=youtu.be - doesn't tell you everything, but better than the manual Stanley ship with the product, which is just a collection of hard to decipher graphics.

1. Make sure the side lock is unlocked.
2. Push the thumb tab all the way to the front of the blade handle.
3. Insert the blade in the opening, you may notice two notches on the top side of the blade.
4. Press the small blade release button as you slide the blade into the knife. You may have to jiggle up and down to get the two notches on the blade fully into the handle.

If properly inserted, the exposed area of the blade should look very close to an equilateral triangle.

make sure both notches of the blade are inside the handle. They notch into the thumb lever.

good luck
