Sara and Jacob Witzling make beautiful and unusual cabins in a rainforest. On their YouTube channel, Cabinland, they demonstrate how they build their wilderness retreats.
Much wood must be cut not only for the lumber, but also for firewood. This means that Jacob swings axes a lot. To make it more efficient and/or absurd, he's welded custom axes. This Instagram video details 8 of them. The triple axe could actually be practical, but the flail axe blade strikes me (or hopefully doesn't) as dangerous to swing around.
Even if these axes aren't always useful for chopping wood, the Witzlings are, to say the least, amply prepared to survive a zombie apocalypse.
