How to change stanley 99E 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

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.

Push the blade out as far as it will go and hold in the button on the side while slideing blade in and out.

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.

The 20-115 uses a quick release lever at the front of the saw. Opening the level by hand with a forward motion will unlock the blade tension allowing you to replace the blade. Pull the level closed to restore tension to the new 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.

Easy-open lever for quick blade change.

There is a SLOT in the end of the knife. Simply insert the strip of new blages in to the slot and you are ready to go.

Good luck. :)
