I offer a 3D model of the Sai blade associated with ninjas!
The bade is made with a clean geometry with quads and triangles only, except the caps of culinders. In the case of the caps, the brim is assigned with sharp edges that allow to subdivide mesh without problems. Whole model is made out of one mesh only, without boolean operation.
There is a simple rig bone, allowing for a 3D manipulation of the blade position. It is exported with .fbx file included.
The lower-poly version has normals baked from a high-poly version. Both models are included as .obj. files.
All the textures are 2K, including: Base Color, Roughness, Metallic, Normal, Height and AO. The images are packed within the blend file but also are attached packed within archive file.
Please, see the quality of the mesh in attached images and the 3D model in a youtube preview.
