Wood with an exceptionally high Janka hardness, like the Allocasuarina luehmannii, can be very difficult to cut and chop with standard tools. Some key points:

It would require a very sharp axe and a lot of force/effort to chop through this wood with an axe. A dull axe would likely just bounce off or get stuck.
It can dull chainsaw blades quickly and may require a more powerful chainsaw.
It can be hard on power tools in general and shorten the lifespan of cutting discs, blades, etc.
It may require pre-drilling and screwing/bolting instead of nailing due to how hard it is.

So while you can cut it with the right tools and blades, it does present more challenges than typical softer woods. The extreme hardness is what makes it durable for uses like flooring or construction, but that same hardness makes it much more difficult to work with manually or with standard tools.
