Something I have found - while spreading toast with a thick but smooth paste such as cream cheese or chocolate spread, is that a serrated knife can leave elegant ridges. I find myself attempting to create uniform patterns across the slice.

I propose the zen knife, with a design which optimises for this effect. The main blade of the knife is straight and flat, to allow application of an even base coating. The reverse side of the knife is a secondary edge, with a shorter section holding a suitable wavy edge. Neither side is very sharp, and the tip is rounded to a large radius, ensuring that this item would be unsuitable as a weapon.

With this knife, one may create highly emotive zen toast, with ripples surrounding features such as olives, raisins, smarties or other small food items.

I'd change that part though.

A knife with no handle and no blade

How is this functionally different from a partially serrated blade, with a few inches serrated near the handle?

The substrate application blade, being straight and unbroken is easier to use.
The styling edge is both at a more convenient angle (raising the handle away from the surface) and has the optimum form to lay down elegant ridges.

Can you incorporate water features and boulders at that scale? Oh yes.

Surely spreading Samurai strudel could rival bonsai eventually.

But never over pay, as they are wont to snarkily infer that change comes only from within.
