Your right a gladius doesn't have a blood gutter and neither does this sword. It has a fuller.
http://science.howstuffworks.com/sword-making1.htm “Fuller - Often called the blood groove or gutter, the fuller is a narrow groove that runs most of the length of many swords. Most people believe that it is there to allow the blade to be easily removed by blood escaping through the channel, thereby reducing suction. Contrary to popular belief, the fuller is not a channel for blood to run along. The actual reason for the fuller is to decrease the weight of the blade without diminishing the strength. Use of a fuller allows a blade smith to use less material to comprise the blade, making it lighter without sacrificing too much structural integrity. This is similar to the use of an I-beam when building a skyscraper. “
The design is Viking in design. You see it in the pommel.It would be nice to find it is an Uthbert original design.
