How to install the blade of a manual shaver

Preparation and precautions before installation:
Before we start, we have to prepare a new blade and a clean and tidy working environment. Remember, be careful when installing and removing the blade. Don't touch the front of the blade directly. It is very sharp and you may accidentally hurt yourself.
Installation steps of retro butterfly structure:
This razor is quite simple to install. First, turn the knob at the bottom and the blade will open automatically. Pinch the two sides of the blade from the side, and be careful to avoid the sharp edge! Then, align the positioning column of the blade holder and gently put the blade on. Turn the knob back and the blade will close! Isn't it very simple?
Installation of three-piece structure razor:

Next, flip the top cover and lay it flat with the positioning column facing up, then pinch the two ends of the blade from the side, align the positioning column of the top cover, and gently put it down. Cover the bottom plate, screw on the handle, and you're done!
General installation tips and inspection:
No matter what kind of razor you use, make sure that the blade and the razor interface fit tightly together when installing, leaving no gaps. After installation, gently shake the blade to check if it is firm and not loose. This way you can use it with more confidence!

Also, remember to clean the outer shell and the inside of the razor every time you use it, and it is also necessary to replace the blade head regularly. This way your razor can always stay clean and sharp!
