I should have provided a link to the site where I got those spear pictures.  It's the British Museum's "Compass Index".

A great resource for looking up  objects!  About those spears (from the website):

Broad Spearhead:

Early Anglo-Saxon, 6th century AD
From Grave 51, Great Chesterford, Essex
This spear was found lying close to the right shoulder of a man who was also buried with a knife, probably suspended from the waist belt which was fastened by an iron buckle. A pair of bronze tweezers lay by his right elbow. Spears are the most commonly found weapon in Anglo-Saxon England. They could be used as a thrusting weapon in battle or as a hunting weapon, essential to bring down large game such as red deer or boar.
The spear has an angular blade decorated with ring and dot motifs inlaid in copper-alloy. The spear has a long split socket with a rivet still in position. The open end of the socket is ornamented with a finely executed gilt bronze band. This is decorated with a frieze of four Style I animals, which are distinguished from each other by tiny details: each head differs in the style of the beak as do the design and position of the back leg and foot; one animal has its back leg and body transposed.
Length: 6.4 cm (max.)
Length: 43.4 cm

Skinny Spearhead:

  Iron spearhead with silver and copper decoration
Viking, late 9th-10th century AD
London, England
This large and elegant spearhead was found in the River Thames in 1848. It formed part of the collection of the pioneering Derbyshire archaeologist Thomas Bateman.
All free men in Viking society were entitled to own and carry weapons: spear heads are the most commonly found weapon of the Viking period. Although often discovered in graves, there is much discussion about why so many weapons from this period were lost or deliberately put into rivers, notably the Thames in the London area.
The blade is slender and tapering, with a long socket. The socket is completely covered with rings of twisted silver, and copper wires are inlaid into the iron surface in a herring-bone pattern. This decoration is typical of the craftsmanship of the Viking smiths in Norway. One substantial rivet attached the spear head to a long wooden shaft, making an effective weapon for both hunting and fighting.
Length: 53.5 cm

I enjoyed looking at your website the other day.  Great info and it makes my husband's constant tinkering with building homemade 3-D cameras look reasonable :-)
