Hi! I'm Drew Finn here for Expert Village. Now we are going to talk about standard hand tools and how to use them. We are going to show you how to replace the blade in your retractable razor blade. The blades are very inexpensive and when they start to get dull, you'll have to change them, so I will show you how to change them. Most of them have one screw on the side. Different manufacturers they come apart differently. Some have sort of a hook in the back that you have to hook them in But just take them apart, pay attention when you are taking them apart and it won't be a problem. Okay let's take it apart and show you the what the inside looks like and how to change the blade. So we remove the screw, disassemble it. There is a place back here to store the blade. We have the blade itself in the traveler and these blades can just be lifted out or replaced or flipped over because you've got two cutting edges and if you have already gone through one, you can flip it over. When you are putting the blade back in, be sure you get it in the right orientation. This particular one we need to be like this when it comes out so what you do is line it up the way that it was before, making sure the bottom edge is lined up along here and the top edge is usually little notch that catches and the tops of these are little cutouts and that is the notch to orientate it so that it doesn't slide back and forth in the device. So we pop that back in there, put the cover on and set the screw. We tighten it up and see that it works fine.
