Another important thing, of course, with the plane is having a sharp blade. So, sharpening these blades can be done in a variety of different ways. Some people use sandpaper, like I was using for flattening the sole, working their way up through the different grits until you get into the thousands. Oil stones. Water stones. All, of course, classic methods. Some people also use grinders to get the edge on there to begin with. So, lots of different methods and which one is right for you, it depends on how much you want to invest in equipment and your time and energy and money, how to do the skills. But, you do need to sharpen when you buy these planes or, if you’ve gotten one from a flea market. They’re definitely not going to be sharp enough to use in a shop. They’ll feel sharp, but they’re not going to be sharp enough for really good woodworking.
