It makes small cuts or holes in things. This helps make weak lines so you can tear or split things easily. The blade has sharp parts and spaces with no edge. This pattern is called the &#8220;cut and tie&#8221; ratio. You see perforated knives when you open packages or tear notebook paper. They also help remove labels.<\/p><p>The table below lists the main technical details and uses for a perforated knife:<\/p><figure class=\"wp-block-table\"><table><tbody><tr><th>Di\u1ec7n m\u1ea1o<\/th><th>Chi ti\u1ebft<\/th><\/tr><tr><td>Nguy\u00ean v\u1eadt li\u1ec7u<\/td><td><a target=\"_blank\" rel=\"noreferrer noopener\" href=\"https:\/\/maxtormetal.com\/vi\/san-pham\/luoi-dao-duc-lo\/\"><strong><em><u>Th\u00e9p t\u1ed1c \u0111\u1ed9 cao (HSS), Th\u00e9p d\u1ee5ng c\u1ee5, Th\u00e9p kh\u00f4ng g\u1ec9, Cacbua vonfram, B\u1ed9t th\u00e9p Metallurgy<\/u><\/em><\/strong><\/a><\/td><\/tr><tr><td>H\u00ecnh d\u1ea1ng l\u01b0\u1ee1i dao<\/td><td>Straight, Rotary, Toothed, Circular, Custom shapes<\/td><\/tr><tr><td>Nguy\u00ean l\u00fd ho\u1ea1t \u0111\u1ed9ng<\/td><td>Applies pressure to create intermittent cuts; cut and tie ratio controls tearability and strength<\/td><\/tr><tr><td>\u1ee8ng d\u1ee5ng ph\u1ed5 bi\u1ebfn<\/td><td>Packaging, Paper products, Food processing, Textile and leather, Manufacturing, Office supplies, Labels<\/td><\/tr><\/tbody><\/table><\/figure><h3 class=\"wp-block-heading\" id=\"h-key-features-and-benefits\">Key Features and Benefits<\/h3><p>Perforated knives have many good points for cutting jobs.

Most serrated knives have a special angle. This angle helps the knife cut better. If you change the angle, the knife may not work as well.<\/p><h4 class=\"wp-block-heading\" id=\"h-apply-even-pressure-during-sharpening\">Apply Even Pressure During Sharpening<\/h4><p>Push gently and evenly when you sharpen. Too much force can damage the serrated edge. Move the sharpener along each groove. This keeps the knife sharp and safe.<\/p><h4 class=\"wp-block-heading\" id=\"h-inspect-for-chips-or-damage-before-use\">Inspect for Chips or Damage Before Use<\/h4><p>Look at your serrated knife before you use it. Check for chips, cracks, or dull spots. If you see damage, sharpen the knife or replace it. Good knife care means checking your blade often.<\/p><h4 class=\"wp-block-heading\" id=\"h-seek-professional-maintenance-for-industrial-knives\">Seek Professional Maintenance for Industrial Knives<\/h4><p>If you use your serrated knife in a factory or for heavy work, ask a professional to sharpen it. Industrial knives need special care. A professional can properly sharpen a serrated knife and fix any problems.<\/p><blockquote class=\"wp-block-quote is-layout-flow wp-block-quote-is-layout-flow\"><p>Note: You should sharpen a serrated knife only when needed.

Safe storage keeps your knife sharp and protects you from cuts.<\/p><h4 class=\"wp-block-heading\" id=\"h-store-with-a-blade-guard-or-in-a-case\">Store with a Blade Guard or in a Case<\/h4><p>Always put a blade guard on your serrated knife before you store it. You can also use a case. This keeps the edge safe and stops accidents.<\/p><h4 class=\"wp-block-heading\" id=\"h-keep-in-a-dry-cool-environment\">Keep in a Dry, Cool Environment<\/h4><p>Store your knife in a place that is dry and cool. Heat and moisture can damage the serrated edge. A dry spot helps prevent rust.<\/p><h4 class=\"wp-block-heading\" id=\"h-avoid-stacking-or-overlapping-with-other-tools\">Avoid Stacking or Overlapping with Other Tools<\/h4><p>Do not stack your serrated knife with other tools. The edge can get dull or chipped. Give each knife its own space.<\/p><h4 class=\"wp-block-heading\" id=\"h-label-and-organize-for-easy-access\">Label and Organize for Easy Access<\/h4><p>Keep your knives organized. Use labels or a special holder.

You should watch for certain signs that show your knife needs a new blade. If you notice any of these, it is time to act.<\/p><h4 class=\"wp-block-heading\" id=\"h-after-noticeable-decrease-in-cutting-performance\">After Noticeable Decrease in Cutting Performance<\/h4><p>You may see your knife does not cut as well as before. The material might tear instead of slicing smoothly. If you need to push harder or the cut looks rough, your knife blade has lost its sharp edge. This is a clear sign you need to replace it.<\/p><h4 class=\"wp-block-heading\" id=\"h-when-the-blade-shows-visible-damage-or-chips\">When the Blade Shows Visible Damage or Chips<\/h4><p>Look closely at your knife. If you see chips, cracks, or missing pieces on the edge, you should stop using it. Damaged blades can break during use. This puts you and your work at risk.<\/p><h4 class=\"wp-block-heading\" id=\"h-following-manufacturer-s-recommended-replacement-schedule\">Following Manufacturer\u2019s Recommended Replacement Schedule<\/h4><p>Manufacturers often give a schedule for changing your knife blade.

It also helps you avoid sudden problems.<\/p><h4 class=\"wp-block-heading\" id=\"h-if-the-blade-fails-to-cut-cleanly-or-leaves-jagged-edges\">If the Blade Fails to Cut Cleanly or Leaves Jagged Edges<\/h4><p>A good knife makes smooth, straight cuts. If your knife leaves jagged or rough edges, the blade has become dull. You should replace it right away to keep your work neat and safe.<\/p><h4 class=\"wp-block-heading\" id=\"h-when-switching-to-a-new-material-that-requires-a-sharper-edge\">When Switching to a New Material That Requires a Sharper Edge<\/h4><p>Some materials need a sharper edge for a clean cut. If you plan to cut a new type of material, check your knife first. If the edge is not sharp enough, put in a new blade. This helps you get the best results.<\/p><blockquote class=\"wp-block-quote is-layout-flow wp-block-quote-is-layout-flow\"><p>Tip: Always check your knife before starting a new job. A fresh blade saves time and gives you better cuts.<\/p><\/blockquote><h3 class=\"wp-block-heading\" id=\"h-warning-signs-of-wear\">Warning Signs of Wear<\/h3><p>You can spot blade wear by looking and listening.

Replace the blade if you see any damage.<\/p><h4 class=\"wp-block-heading\" id=\"h-inconsistent-or-uneven-cuts\">Inconsistent or Uneven Cuts<\/h4><p>A worn knife blade may leave uneven or wavy cuts.
