Several common segment cutting methods

Author Weibo @morrowind_l1, Segment Cutting Shovel/Wide Shovel + Grooving Device The Segment Cutting Shovel is a wide shovel specially designed for segment cutting. The wide shovel has an edge on one side and can be pushed directly to shovel out a 90-degree angle. You can also use an ordinary wide shovel to dig out the trench and then shovel it, and the effect is almost the same. The width of the wide shovel limits the width of the cut. If you want to cut wider, you need to cut it in sections.

Choose the appropriate thickness Use a plastic card close to the leather to cushion the right end of the wide shovel, and press the leather with a ruler or an acrylic plate to ensure accurate and flat cutting.

The card uses double Surface tape works better when fixed on larger glass panels. In order to prevent the glass plate from reflecting my handsome self, I covered it with a cutting mat... I had to use a piece of iron to press the card, but it would become loose and not easy to use.

Guaranteed to be basically flat Just shovel it straight and then trim it.

The effect is okay .

Groove Controller With the widening shovel, the card can also be used to confirm the depth when digging trenches.

First dig a groove of appropriate depth and then shovel the edge along the groove. I don't have an ordinary wide shovel, so I have to pretend with a sectioned shovel.

The key to operating a wide shovel is Make sure that the trajectory of the blade is parallel to the leather surface, or shovel slightly upwards in sections. If you go downwards, you will overcut, and the leather will basically be scrapped. 2. Grooving + side cutting segments with a thinning knife The knife used for side cutting must be sharp enough, and the back of the blade must be straight.

After digging the groove, place the leather close to the card of appropriate thickness, and cut the thinning knife close to the card. The left hand should move with the blade, and press the leather to prevent The leather material moves up and down, resulting in uneven cutting or even cutting through the leather surface. Use a ruler or an acrylic plate to press harder. You can paste masking paper on the blade as a mark according to the cutting width to prevent cutting too deep when the groove is not dug in place.

This paragraph The difficulty of the cutting method is that you need to be very careful and meticulous if the upper groove is to be perfectly connected with the side cutting. Cutting too deep or digging the groove too deep will reduce the strength of the leather. In addition, the difficulty of side cutting is proportional to the width of the section, so it is not recommended. Use this method to cut overly wide sections. It is actually possible to cut the top directly with a knife without digging a groove, but it is more difficult than digging a groove, so it is not recommended. 3. This method of cutting directly with a thinning knife is actually It is similar to the segment cutting method introduced in "Leather Crafts 19", but the method in the book is too violent, the cutting angle is too large, and the limited sharpness of the leather cutting knife is directly pushed with the shovel. It can be applied to many types of leather. Limited. The inclined edge thinning knife with the blade facing downward during thinning can perform an improved version of violent segment cutting. It can perform larger width segment cutting, and it is also feasible to directly perform overall thinning in segments.

This won't work without a glass plate, so I'll make do with a small one.

From the right Start by cutting the blade diagonally along the marked line. Stop when you reach the approximate cutting depth and prepare to cut forward and to the right. While drawing, press down on the blade until the blade surface is parallel to the leather, stop pressing, and cut smoothly. You can perform multiple tentative cuts on the small section on the right to find the appropriate cutting depth to prevent cutting too thin at one time. It is also possible to place the universal card on the right to confirm the depth. After finding the appropriate depth, you can cut it in sections from right to left. There is no need to cut off the cut off part on the right side. Covering it with the knife will make it easier to find the feel and keep the thickness consistent after the cut. This is cutting in sections from right to left. You can also cut in sections from left to right. Cut off one layer directly from the left end and then cut layer by layer until you reach the appropriate thickness. Each has its own characteristics, it depends on personal preference.

After cutting Use a knife for leveling and trimming. The step difference is an inclined plane due to the insertion of the knife. If necessary, you can use a groove pusher or a section widening shovel to push it out at a right angle. Now that the introduction is complete, let’s conclude.

Sectional cutting in leather craftsmanship It is an important leather edge processing method. The efficiency of manual segmentation is limited. Leather friends who have the conditions should go to 801, which is machine cutting.If the location or details cannot be processed, hand tools can be used. Handicrafts are not just about pursuit of all-handwork. You still have to use machines when necessary. The time saved can be used to improve the design and other details.
