With the Japanese weapons they were designed as weapons, surgical tools for dissecting and killing a person in combat
That line in Kill Bill where Hanzo describes the Sword he made, with the English subtitle translation as "something that kills people"
This specifically applies to the KATANA of course
The other weapons Yari, Naginata, Bisento, Kodachi, Tanto, Kusurikama, where all designed the same way
Even the staff weapons, Bo, Jo, Hanbo and Tanbo, were developed not just as a "broken spear" but proper red oak built and measured weapons
This applies of course to the "Samurai" kobodo, starting with the Katana
The NINJA approach, as we discussed, was different as the weapons, starting with the NINJATO sword were viewed as tools, simply made, and disposable
Shuriken were simply made and designed to literally be thrown away
The Shoge and Shuko were climbing tools that doubled as weapons
The Kunai was adapted from a digging tool and used in Onshinjutsu
When we get to the Middle countries
Filipino Kali
Thai with Krabi Krabong
Silat in Malaysia
we see weapons such as the Machete
Swords and short spears
Knives
that are tools adapted as weapons
In Okinawa the KARATE Weapons were developed from farm tool
The BO is just a simple pole
Nunchaku are rice flails
Tonfa was a handle
Kama are farm sickles
Sai was a tool
these are tools adapted to be Weapons when needed
CHINA is a bit different as they have a rich culture of proper developed weapons and systems for using them
our main interest in China is the Wing Chun weapons
the sophisticated BART CHARM DAO, the "butterfly swords"
and the more basic and direct KWANE, the "Dragon pole" , not at complex as the Shaolin pole or spear systems
So for the UNARMED Combat
KARATE flows from the KOBUDO weapons
KENJUTSU and KOBUDO flow into JUJUTSU
NINJA schools take the movement from mainly the SWORD, the BO at distance and the HANBO relates to TAIJUTSU
KRABI is the basis for Unarmed Combat in THAI
KALI in Unarmed range, Panantukan - and relates to KENPO
SILAT weapons into Unarmed
WC can be seen best in the DAO, and the KWANE at the long range
