The viking sword and Exploration

The Viking sword +ULFBERH+T
 We recently learned about the +ULFBERH+T sword. It is a sword that has crucible steel in it. It is a steel that has very few dots and slags as they call them in it. It is better then other steel of its time. To make it you would have to heat the iron and coal to a very high temperature, and in Europe it seemed that no one could do it. But in the middle east there was swords made with crucible steel. This means that the Vikings must have gone to there and got the Crucible steel. Historians think that they went on the Volga trade route. This is a route from Sweden to Iran it is mostly on water. It goes along the Volga river and lakes. Then it goes to the Caspian sea and past it into modern-day Iran and Iraq. Vikings might have got Crucible steel from here. I think they did and so do others. Then they would have gone back to Scandinavia in small rowboats. There they would shape the steel into the sword. But the inscription of +ULFBERH+T is still a mystery. No one knows who Ulfberht was. Christian Abbots and Popes put a cross in front of their name. Maybe this was a Christian Abbot who had made it. But the Christians were forbidden to Trade with the Pagan Vikings. Maybe a Christan viking had made it. Or maybe just a Viking had made it. Or it was a brand name. But it showed that the sword was made with Crucible steel. Other Ulfberht swords were made but they did not have Crucible steel in them. They were fakes. They had the letters +ULFBERHT+ on them. Someone was trying to copy +ULFBERH+T. If you had a +ULFBERH+T sword you would be highly honored as a great and rich warrior. +ULFBERH+T Swords were like the best kind of weapons. 

Exploration
The Vikings who originated in Scandinavia, explored from North America to Pakistan.
They were great explores on sea. They were not the best on land though. Proof that they had gone to North America and Pakistan is real. A viking ruins was found in North America and Statues of Buddha were found in Viking graves. The Vikings also went to Greenland, Iceland, Newfoundland,  Israel, Constantinople, Italy, Spain, Morocco, Russia, France, England, Ireland,Greece, Iraq and Iran. Like you probably know Vikings did not have horns on their helmets and there are also peaceful and economic vikings.
