Tools - The Essentials, The Hobby Knife Alternative, Part 4 Changing The Blade

I realize most would know how to change out one of these knives.
But for those who haven't used one before -

On the left is a dull blade tip. Notice the diagonal break-off scored lines.

On the right is the back end of the knife. Press the ribbed button and slide off the end clip.

Only extend the blade "one click" outside of the wrapped metal end. You only want to break off one segment of the blade, down the score line.

The end clip piece has a slot molded into the back end. Slide this over the end of the blade. Press down on the clip and the blade should break off down the score.

When you've broken off all the available tips, the blade is replaced.
Remove the end clip again. Slide the black center hold piece out the rear.

There is a single round pin that goes into the hole on the blade strip end. Remove the old blade. Install a new, long blade over the round pin.
Slide the blade strip back into the center of the of the knife. Click the yellow rear clip in place.

You're ready to go!

The inset picture shows the back of the rear clip. the yellow overhang can be clipped on your shirt pocket.
