Kushiro Tools is a consolidated collection of free modeling and utility addons developed by Kushiro. It packages all of the developer's non-experimental free tools into a single installation, making them accessible through a centralized two-column pop-up submenu.

The bundle includes a wide variety of tools focused on mesh manipulation, topology management, and hard surface modeling. Included operators range from topology correction tools like Even Loop, Ngon Loopcut, and Quad Adder, to structural utilities like Quick Bridge, Quick Fillet, Align Edges, and Flatten Face.
