The modern mind has a strong need to define things and put them into neat boxes. When we try to define something like, "What is a Seax?" we have to remember our ancestors didn't share the same propensity. This can make things like categorization difficult. With that in mind, a "seax" is really defined by a combination of the blades profile and the hilt construction. A Seax would have a single-edged blade, often with a clipped point but not always, with the blades tang inserted into a rather simplistic grip lacking a guard or pommel and secured by some kind of natural epoxy. Sizes could range from very small, eating type knives to long sword like proportions. A longer example might be termed a "langseax", lang meaning "long". In such a case, if we read a period account wherein Snorri chops of Siggurd's hand with a "langseax" we can assume with some degree of certainty that it was a larger sword like example.
