Key Takeaways
- If you want to move the sliced parts, you need to use the Selection tool to select the parts.
- The Knife tool can only slice vectors, not images.
How to Use the Knife Tool in Adobe Illustrator
Before we embark on this artistic journey, let’s familiarize ourselves with the Knife Tool. So where’s the Knife tool in Adobe Illustrator?
Located in the Illustrator Toolbar, the Knife Tool is represented by an icon resembling a small scalpel. When selected, this tool lets you cut through paths, shapes, or groups, dividing them into separate objects.
Note: There’s no keyboard shortcut for the Knife tool.
Found it? Let’s make some cuts.
Step 1: Before making any cuts, you need to select the object or group you wish to slice. Click on the desired element with the Selection Tool (V) to highlight it. Alternatively, you can select multiple objects or a group by holding down the Shift key while clicking each item.
Step 2: Choose the Knife tool from the toolbar. Position the cursor where you want to start the cut and click once to set the starting point. Then, drag the cursor to the endpoint of the cut, forming a straight line.
Don’t worry about precision at this stage; you can adjust the cut later.
If you want to make precise cuts, hold down the Alt (Option on Mac) key while using the Knife Tool. This enables the “Smart Guides” feature, which helps you align the cut accurately along edges, anchor points, or guides. Smart Guides act as your virtual assistants, ensuring your cuts are pixel-perfect.
Apart from making cuts through objects, the Knife Tool can also split shapes and paths. By selecting a single anchor point with the Direct Selection Tool (A) and then using the Knife Tool to slice through it, you can split the shape into two distinct parts.
Once you’ve made your cuts, you can use the Selection tool to move and separate the individual parts.
Tips for Precision
Smart Guides: If you want to be extra precise with your cuts, make sure to turn on Smart Guides (View > Smart Guides or use the shortcut Ctrl + U/Command + U). These nifty guides will help you align the Knife Tool accurately.
Snapping: Take advantage of snapping options (View > Snap to Point or use the shortcut Shift + Ctrl + ’ or Shift + Command + ’) to snap the Knife Tool to anchor points and paths, ensuring clean and accurate cuts.
Undo and Edit: Don’t worry if you make a mistake! Illustrator’s undo function (Ctrl + Z/Command + Z) is your safety net.
Advanced Techniques
As you become more comfortable with the Knife Tool, you can explore advanced techniques:
- Divide Objects Below: By holding down the Alt/Option key while cutting, you’ll activate the “Divide Objects Below” option. This will cut all objects below the topmost object intersected by your cut.
- Cut at Selected Anchor Points: If you only want to cut at specific anchor points, hold down the Alt/Option key and click on those anchor points with the Knife Tool.
- Cut Across Multiple Shapes: To cut through multiple shapes at once, group them together first. Then, apply the Knife Tool to the grouped objects.
Final Thoughts
Now that you have mastered the art of using the Knife Tool, it’s time to unleash your creativity. Experiment with different shapes, paths, and group combinations. Combine the Knife Tool with other Illustrator features, such as gradients and brushes, to create mesmerizing artwork that pushes the boundaries of your imagination.
