The point where the corner of the framing square meets is known as the pivot point. It represents the 90 degree angle to help carpenters in measuring angles. All they need to press the fence against the edge of the board & use their other finger to hold the pivot point. By carefully swinging the tool from that point, they can easily get the desired angle for the crafting. After that, all that’s remaining is to mark that angle for later use.

Being able to mark this angle on any board, makes it much easier on joint corners for window frames, cabinets, & furniture components.   

Use of Line Scriber to Mark Length for Trimming

The 0.64 cm notches located in between the interior of the precision square are often used to mark lengthwise cuts on the board. Not only that but with the help of those notches you can also mark the area which required trimming. To do that, you need to set the fence against the edge of the board to the frame at 90 degrees. Then needs to select the slot you wanted to use. After that, you need to insert the tip of your pencil to draw the line parallel to the board’s edge. This mark that you made will indicate where you need to cut along its length.
