Frysta is an Icelandic word meaning "to freeze", it also means "frozen" in swedish.
This skin appears based upon a Type II Oakeshott, which includes a fuller, oblate pommel, and was designed to be used one-handed. The term "longsword" is generally regarded as ambiguous, however, it can be applied to one handed and two handed swords, so the application of the term in this context is not inappropriate. In fairness, there are some vaguely Roman influences, namely, the generally thick and wide blade, and the angular point being similar to a Legionnaire's gladius, or a cavalry's spatha
This skin is also similar to viking ulfberht swords
