Expert Woodworker Demonstrates How to Make a Cake Knife That Cuts Hexagonal Shapes

Expert woodworker and engineer Matthias Wandel demonstrates how to make a hexagon cake knife, an idea that was inspired by his wife who wondered aloud how she should cut a cake.

This project started when Rachel said “Now I have to cut the cake into squares or triangles”. My immediate thought was “why not cut it into circles, or hexagons?”. This got me thinking about a good method of cutting a cake into a hexagon honeycomb pattern. The easiest I figured, was to make a knife that snakes through the honeycomb pattern …Testing the knife by pressing it down on some pine. I had actually shaped the handle to have a slight curve on the bottom of it so that the knife can be rocked back and forth a bit for cases where it needs to slice through some tough cake or pizza bottom. It left a nice indentation in the pine. so I’m confident that it can slice any cake.
