The making of the Maketikus utility knife

First probing sketches.

With the help of foam models we pinpoint most actively used areas of the handle.

Clay models assist in our search for the right flow of the lines.

Keeping the foam modeling rolling as well.

Trying some cutting edge extremes in cardboard.

Sketching a handle with contrasting surfaces. Mixing up smooth planes with straight-cut basic shapes, pushing it as far as 3-D frames and grids.

Cutting back to initial multi-faceted concept and carving out fine details and elements.

3-D printing a series of models guided by the main concept and agreed-upon size and shape, while modifying and perfecting each new outcome on the fly.

Mapping the textures.

Test renderings.

Selecting a color.
