I learned to use a combination square in high school shop class which can make both 90-degree lines and 45-degree lines which are useful in creating joints.<\/p>\n\n\n\n I received this combination square from Gmarket which included a free mechanical pencil that works well as a carpenter pencil.<\/p>\n\n\n\n However, when I checked this combination square with another framing square, then I discovered it was not in alignment. It shows a lot of \u201cdaylight\u201d when held against another square and straight-edge. This is a significant amount of misalignment and this could mess up every project for a boy if he uses a faulty combination square like this.<\/p>\n\n\n\n I also tried a second straight edge to confirm that the combination square was out of alignment so there was two different tools used to confirm it was not \u201csquare\u201d as it should be. (The image above moved a bit as I took the image but when it was held carefully in place against this straight edge, it does show this combination square is not \u201csquare\u201d just as the other framing square also revealed. Therefore, I returned this faulty combination square which was also chipped on one edge. It was of much lower-quality than the combination squares I used in my youth in shop class.<\/p>\n\n\n\n This is called a \u201cRafter Square\u201d or it could also be called a small \u201cFraming Square\u201d because carpenters use these when building houses to determine the pitch of the roof they are making. But in our case we just want a simple straight-edge for boys to mark a straight 90-degree line or a 45-degree line if they need to cut material to create a joint. The cost of this \u201crafter-square\u201d is only 6,200 KRW but is a better price than the combination square that costs 14,700 KRW (plus shipping). This \u201crafter-square\u201d is one solid metal-cast piece so there is nothing that can become lose or become misaligned. It is for this reason that it is a good choice for boy-projects since it is inexpensive and solid and accurate and will last a lifetime.<\/p>\n\n\n\n This \u201crafter-square\u201d is small sized and easy to carry and store but can make straight lines on material for 90-degree and 45-degree markings. When buying tools it is sometimes better to get something solid metal-cast like this which has a better price and is more accurate than the adjustable combination square.<\/p>\n\n\n\n As with most tools these can usually last a lifetime if they are taken-care of well and are not abused or destroyed by neglect. This is especially true with durable \u201cmetal-cast\u201d items like this simple \u201crafter-square\u201d which has no moving parts and is sturdy and not easy to bend by accident.<\/p>\n\n\n\n See the link “Stewardship of Assets<\/a>” for more details.<\/p>\n\n\n\n![\"\"](\"https:\/\/kmi2.kr\/wp-content\/uploads\/2022\/08\/20220824_162803-768x1024.jpg\")
