A kunai is an ancient Japanese kind of gardening tool or trowel. In the hands of a martial arts expert, could be used as a multi-functional weapon. You may have seen this weapon a lot in Naruto Anime Series. Today I will show you how to model kunai dagger. Consider this as a warm up before I write Naruto Modeling Tutorial. This Naruto Modeling Tutorial is a complex tutorial. So, you have to wait a little while before I can publish it. Btw, Modeling Kunai Dagger Tutorial is intended to beginner level.

1.Open your 3ds max or reset. Create several primitives in viewport: Torus, Cylinder and Pyramid.

Create Torus in Left viewport. Use Radius 1=24, Radius 2=7, Segments=14, Sides=8.

Create Cylinder in Front viewport. Use Radius=8, Height=124, and Height Segments=5.

Create Pyramid in Front viewport. Use Width=72, Depth=72, Height=228, and Height Segments=2.

When finished move and arrange all three objects position like image below.

2. Now, let's modify Cylinder. Select Cylinder. Right click and choose Convert to>Convert to Editable Poly. In Selection rollout, activate Vertex selection. In Left viewport, select a ring of vertices in the middle and move them to the right.

Change selection to Polygon. Select a ring of polygons. Then use Select and Uniform Scale Tool to enlarge the selection. When finished turn off the Polygon selection.

3. Move on to another object. Select Pyramid. Click Select and Rotate Tool. Enter Y=45 in coordinate input box in the bottom of the screen. This will rotate the pyramid a bit.

4. Next, convert Pyramid into Editable Poly. Activate Vertex selection. In Left viewport select all vertices in the middle.

In Edit Geometry rollout use Constraints=Edge. Then, move selected vertices to the left. Using Constraints you can move vertices without ruining original object shape. When finished, change Constraints to None.

Next, select all vertices at the left side of Pyramid. Using Select and Uniform Scale Tool, scale down until its size fit the left Cylinder. When finished, turn off Vertex selection.

5. Make sure modified Pyramid is still selected. In Edit Geometry, click Attach button and click other two objects in the screen. All three objects is now combined into one.

6. Next step, connecting the gap. In Modify tab, activate Polygon selection. Select all polygons opposite to each other like image below. There are 5 polygons you need to select. To select more than one polygons hold Ctrl while selecting. To reduce selection, hold Alt while clicking.

After that, click Bridge button.

7. Final Detail, change to Vertex selection. Select vertices in the middle of object like image below and move them to the right. Turn offf Vertex selection.
