How do you load a new blade?

You unscrew the screw closest to the blade

Slide the blade holder all the way out, press on the tab as shown in picture. Pull on blade with other hand. Blade slides right out.

HI!Kindly pull the button on the end of the knife and then after you remove that you can now put the blade of your knife.

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.

there is a little black button on the end where the blade comes out. With the blade in the out position,push in the button and pull out the blade. With button pushed insert new blade or turn the old one around to use the other end.let go of the button and you are ready to go.

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

This knife is ****. To load... you have to push the slide all the way forward. Make sure the switch is set to unlock. PINCH THE BLADE WITH YOUR FINGERS AND WIGGLE IT INTO PLACE. Then you have to use every ounce of thumb power to relock the switch.

Once you are done, the blade will still come out in 9.9 / 10 times you cut something.

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.
