Possibly 'Ba' or Dian culture ge-halberds . Eastern Zhou period. The upper one is very similar to a Dian culture ge shown in 'Weapons in Ancient China' even down to the detail on the tang.
This style of dagger axe is similar to a Chinese archaic form, more in appearance like the Shang (17th-12th centuries BC) or the Western Zhou 'ge' or 'ko', yet in border areas like Sichuan & Yunnan the shape persisted as late as the 8th-3rd centuries BC.
Like the Shang & West Zhou blades it has a possible connection to the stone battleaxes of the neolithic period and still these pieces cannot be accused of being crude or backward when the fine detaill on them testifies to the skill of regional bronze smiths.

Details on tang, tribal weapons are typically quite decorative compared to weapon produced en-mass for fuedal state armouries in Zhou 'China' of this period.
The weapons of ancient tribal peoples in the modern provinces of Yunnan & Sichuan in particular illustrate the individual & more personalised nature of warriors in tribal societies.
As noted in the thread on Dian culture swords the tribal-periphral 'non-Chinese' peoples had a sense of personal identity in weapons not seen in the mass produced weapons outfitting Zhou fuedal armies. In the Central Kingdom decorated weapons were a feature of rank and status and an exception to the rule whereas in tribal groups certain motifs are almost standard features, i.e cloud motifs on Dian axes.

Large 'tribal' halberd/ge

Anthromorphic figure. (man-animal)
Half man & half beast creatures can be seen on bronze vessels and even decorating coffins in the East Zhou. In some cases the creatures are interpreted as gaurdians for the deceased. Given the shamanistic nature of religions outside the Zhong-guo 'Zhou' cultural area the meaning of this odd human-like figure cannot be said for certain.

Liaoning province style sword.
This is a 'non-Chinese' type which disapears from the region after expansion by the state of Yan. After this time 'Chinese' style halberds are found in graves, and this is similar to the decline and eventual extinction of local cultural weapon types in the south which were later replaced by Han dynasty style weapons.

''Although the origin of the Korean bronze age culture may be traced back to the Liaoning bronze dagger culture, the Korean bronze dagger culture has its own unique features, as demonstrated by the typology and styles of Korean bronze ritual objects, which differ from the Liaoning bronze dagger culture.
.....The Bronze Age in Korea may be divided into the earlier Liaoning bronze dagger culture and the later Korean bronze dagger culture.
The Liaoning bronze dagger culture first appeared in the Liaoning area of the north-eastern China in the beginning of the 10th century B.C. This bronze culture is famous for its unique bronze daggers. The Liaoning culture spread into the northwestern and mid-western areas of Korea from the Liaotung Peninsular through the coastal routes of the Yellow Sea and from there it spread into all of Korea.
Sites of the Liaoning bronze dagger culture typically contain bronze daggers, socketed spearheads, arrowheads, fanshaped axes, chisels and knives, curved jades, tubularjades and round jades, polished stone daggers and arrowheads, etc.
.....Around the 3rd century B.C. Iron culture was introduced to the Korean Peninsular through cultural contacts with the northeastern area of China. The appearance of this culture coincided with the diffusion of knife-shaped currency issued by the state of 'Yon' {i.e Yan state} (Youn; 323 B.C.-222 B.C.), one of the seven Chinese waning states. Iron culture was widespread in southern Korea by about the Ist century B.C.In the early stages of the Iron Age, Chinese iron objects predominated, but iron objects soon began to be manufactured in the Korean Peninsular by the influence of new technology.

''The Liaoning bronze dagger culture is an archeological complex of the late Bronze Age in Northeast Asia. Artifacts from the culture are found primarily in the Liaoning area of Manchuria and in the Korean peninsula. Various other bronze artifacts, including ornaments and weapons, are associated with the culture, but the daggers are viewed as the most characteristic.
Lee (1996) considers that the culture is properly divided into five phases: Phases I and II typified by violin-shaped daggers, Phases IV and V by slender daggers, and Phase III by the transition between the two. Of these, remains from Phases I, II and III can be found in some amounts in both the Korean peninsula and Manchuria, but remains from Phases IV and V are found almost exclusively in Korea.
The early phase consists of an early period of bronze manufacture without daggers, followed by a period of producing violin-shaped daggers. The prime period of production of violin-shaped daggers is dated to the 8th and 7th centuries BCE.
The earliest artifacts from this period are found exclusively in Manchuria, and seem only gradually to have spread to the Korean peninsula. By Lee's (1996) Phase II, however, a distinctive notched form of dagger begins to emerge in southern Korea, suggesting that by this time independent bronze production had begun in that region.
Evidence gained from pottery indicates that the bronze dagger "culture" of this time actually included several distinct cultural groups. One distinct pottery tradition is found in Manchuria and northwestern Korea, another in the Taedong River valley, another in the southwest around the Chungcheong provinces including the Geum River, and yet another throughout the rest of the southern Korean peninsula including Jeju island.
Slender daggers
This later part of the Liaoning is often referred to as the "Korean bronze dagger culture," since it was largely restricted to the Korean peninsula. [1] At this point the Liaoning culture artifacts begin to disappear from the Manchurian area. A new form of dagger begins to turn up on the Korean peninsula, straight and slender.
The greatest concentration of bronze daggers is found in the Geum River valley of South Chungcheong province. Away from this area, the daggers become progressively fewer. This appears to indicate that most daggers were produced in the Geum valley, and the other cultures of the peninsula acquired them primarily by trade. Trade also took place by sea, with artifacts from the Later Phase found in Japanese archeological sites as well.
Lee (1996) divides this phase into two distinct sections: one dating to the 3rd century BCE in which the production of slender bronze daggers predominated, and one dating to the 2nd century BCE in which daggers are often accompanied by bronze mirrors with geometric designs and halberds influenced by the Chinese Qin state . In the first part, a single pottery culture typified by clay-band applique is found throughout the Korean peninsula, but in the second part distinctive pottery types emerge in the northwest and the remainder of the peninsula.
The disappearance of the Liaoning culture from Manchuria appears to coincide with the State of Yan's conquest of that area. Yan brought an Iron Age culture to the region, including its own knife-shaped iron currency, which is also found at scattered locations on the Korean peninsula.''

These weapons are made of two pieces . Hilts are heavy and have in-cast details , binding on blades tang can almost be seen.
It is also possible these 2 parts are not even of the same sword.
