Hello, Go to this youtube website too see video on changing the blade.

How do I change the blade on the quick change/instant change knife? Warning: Blades are sharp and can cause serious injury. Be extremely careful when handling blades. Wear eye protection and dispose of used blades properly, such as wrapping in duct tape.


FULLY EXTEND THE BLADE.
Press down and forward again on the slide button until the button is in the full front of the top slot (0 through 3 in the below picture).

Note- the blade must be extended beyond the 3rd detent position. This will cause the slide button to remain in a down position, allowing the blade release button to operate.

PRESS AND HOLD THE BLADE RELEASE BUTTON ON THE FRONT SIDE OF THE KNIFE. (Step 4 in the below picture)

Note- if the blade is not fully extended beyond position 3) , the blade release button will not work.

Remove the old blade carefully.
Insert new blade.

NOW, RELEASE THE BLADE RELEASE BUTTON.
ENSURE THE BLADE IS LOCKED IN PLACE. If the blade does not retract, try carefully giving a slight tug on the blade to reseat.

Hi.

See here the Stanley knife disassembly. If you have a 99E there may be an additional plastic part that is not shown in the diagram. The plastic tab is located at the back of the blade.

Hi, W/D here.

The blade changing is accomplished by pushing the yellow button and pulling the old blade out. It is reversible. If there is no blade at the ready, there may be more in the body of the knife, which are located behind a swing out panel on the handle. You'll need to push in the yellow button when installing the blade, and once the blade is in, release the button, and moge the blade until it clicks in place.

--W/D--

some stanley knifes require stanley blades only, or make sure the clip blade is in is seated in the grove completely.

On the pivot end of the bladed knife is a black plug that says pull. They actually mean "Push". push it away from the knife body and rotate the handle half it's mounted in, down. The body will rotate in half , revealing the utility blade and more blades in the rear storage.Also note the blade depth adjustment has a locking detent. You have to push it to the right to unlock the utility blade.and push it to the right when retracting to fully retract and lock the utility blade.

Some models has 2 screws on the knife case.unscrew them and you can access to the blade.

Google: how to change blade in Stanley 10-379 utility knife. Stanley website shows how knife & blade look on the outside. Put it together so it looks like that. Sorry, but ain't don't know how to send the picture to you.

If you use the wrong brand of blades, they won't let the knife shut all the way. The notch is cut slightly differently. The same is true for the Kobalt knife I just bought at Lowes. Get the Stanley blades that are right next to the knives - they are the only ones that work.

Sorry.

If you bought the Stanley blades, then I don't know what the problem is. Sorry for that too.
