This page was created from the following thread . This is a common issue for new starters and this will hopefully help anyone trying a 3 pieces DE razor for the first time. This page is part of the Interactive Guide to DE Razor Shaving.
Why incorrect assembly?
When using a new tool, a safety razor can be tricky because it's new. When the base plate is inverted, up-side down, incorrectly placed or assembled, a user can still try and shave with the DE razor. The issue will be that the razor will barely shave or not at all.
Incorrect vs. Correct
Following are a few pictures of the incorrect and correct way to place the base plate while assembling the safety razor.
Installation of the Blade
Now that we saw the correct and incorrect ways to install the base plate, here are the correct way to install a DE blade in a 3 pieces razor.
Picking up the Blade by the edges to avoid any cuts
Placing the blade in the cap
Putting the base plate over the blade
The cap is curving up and the base plate is also curving up
Now that the plate is correctly placed with a blade, let's finish the assembly of the DE razor
Securing the blade by tightening the handle

Make sure that you double check the blade exposure if it's even before using the razor.
