I have made all the objects and the brushes with DpaintV myself.
To modelise the knife, I just took the first knife that I found in my kitchen as a model and that's it. There is great chance that you have a similar knife in your own kitchen.
The handle of the knife was a Form. It was pretty straightforward to modelise such a simple object in the form editor, with XY cross sections, X symmetry and two or three cross sections to make the profile of the handle similar to my model: 15 minutes total. Basically, this is a similar process explained in the Dare to Imagine tutorial to make a thumb and I won't describe it further. This Form was converted (and Merged, because of the duplicated points) as an object. The extremity was made Subgroup to apply a Chrome texture. Otherwise, the handle's texture is just a blue color with a little bit of specular.
For the blade now:
A simple Dpaint V shape in 2 colors, representing the blade profile, was Converted in an object with Faces. The first half of this blade, along say a segment AB, has small teeth which are not very visible on the picture because of the Depth Of Field. These teeth were not present in the original Converted object and have been added to the blade by copying/pasting the object, deleting in the pasted object all the point not in this segment AB, in order to make another object A'B' equivalent to the segment AB of the blade. The first blade object and this new object were Joined, but A'B' slightly below its AB counterpart. Then, AB and A'B' were Fractured equally to increase the resolution of these segments. Then AB Set Edge, A'B' filled Edge, and then, because this filling process created transversal edges naturally looking like teeth, the A'B' edge line was deleted, releasing the teeth pattern of the blade. The all object was then Extruded with a single section to give a small thickness, otherwise the blade would have been a simple 2D shape, except of course at the level of the teeth and edge of the blade. It was necessary to
Joined and Merged some of these extruded points.
A real blade is a 3D form with some sharp edges and so, the MAKE SHARP and MAKE SOFT EDGES function are very important here, to give a realistic look at the blade.
The boundary edges of the object have been made SHARP while the internal edges have been made SOFT, pretty much like a real blade.
The texture of the blade is a Chrome texture, not very good as you can see.
The apples are originally Forms Objects, as the leaves. I used exactly the process described to make leaves in the CadTech website Tutorial section. The brush map on the apple was a DpaintV 16 colors brush applied spherically. They give a touch of color to the picture.
I used 3 French Window textured light sources and a strong Depth of Field to put the emphasis on the knife.
