What are blunt weapons?
A blunt instrument is any
solid object used as a weapon, which damages its target by
applying direct mechanical force, and has no penetrating point or edge. Blunt
instruments may be contrasted with edged weapons, which inflict injury by
cutting or stabbing, or projectile weapons, such
as bullets or shot, are accelerated to a penetrating speed.
What is the difference between traditional and modern Nunchakus?
Traditional Nunchaku was typically made from hard wood, such as oak. The modern Nunchaku can be made from wood, as well as other plastic and fiberglass materials. Also, the rope of the traditional Nunchaku was made of horsehair, while the rope of modern Nunchaku is made of nylon or metal.

How to remove bugle screws from stair treads ?
"Merbau". One of several species also called "Ironwood".
Holy COW - those are amazingly long bugle-head screws for stair tread, unimaginably long for that purpose. There must be some special reason for using such long screws...?
At any rate... you're doing it just as I'd be doing it if I was removing them - try to unscrew them. Some may break - there's nothing to do about that. If they break off badly, leaving part of the threaded shank buried in the tread, you may have to pry up the tread (after removing at least all of the screw heads) as best you can, then you may possibly have to grind off the broken-off screw shanks.
The problem is primarily one of the wood the screws are threaded into, behind the treads. The screws are apparently really hanging onto that wood, so the torque of removing them is not as great as their friction against the wood they're screwed into, but is great enough to break them.
The only suggestion I can offer is... if you can get one to turn at all, turn it slowly and as continuously as possible. Your worst enemy here is a slow squeaking or rattling sound - that's shock waves moving back & forth through the screw, and it increases the likelihood of breaking the screw. Turn as continuously as possible because static friction (the friction of one motionless object against another motionless object) is greater than dynamic friction (the friction of two objects moving against each other), so there's less stress on the screw as long as it's kept moving. Keep it SLOW because the screw will be heating up as you remove it - thanks to friction again. The hotter the screw gets, the more it weakens and the more it expands & binds against the wood it's screwed into.
Slow. Continuous. And... expect to break some.
