Have a Stanley Fat MAx utility knife and unable to open it to load the blade

Don't touch the blade by hand use a pair of pliers. There should be a screw in the center of the handle, just remove it and you will see how to remove the blade.https://youtu.be/pFnbiw88Z8c

Hi Mark,

I have several of them. Are you having trouble getting the handle to open up?

I have found that the blade needs to be all the way in to open it. Also, to get the blade holder to sit right.

If this is not the problem, please reply back. Thanks,
Handie Andie

Not sure exactly because I don't own one, but the review seems to indicate you push the blade positioner all the way forward, and push a release to remove the old one out the front, and then push a new own in until it clicks in place. With the blade positioner all the way forward.
But the review said it did not work well.

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.

If it is a 10-816 then Knife swivels open for easy blade change and clean out - no tools required, much like 10-999
If it is a 10-778, you don't really open it. You press little button on left side, behind the blade wiper, and this releases blade. Push red button on rear of knife, to open blade storage
if it is a 10-999 then press the button on rear and rotate the two halves.

At the back end of the knive (the curved end) press the black piece through the yellow rounded part and the yellow front and the black back will part, now slide the yellow part back to reviel the blade folder. Fit new blade then refit the yellow part on top of the black part and slide the yellow part foward to lock it back in.

The gold looking circle on the side of the utility knife. Just unscrew that and it will pop open then you can change the blade. I looked everywhere and am unable to find the instruction or picture. I own one and that is why I am answering this for you. Please rate

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

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.
