Over the eight years he spent after the incident with Galactic Online James has done some studying and research and has become more technologically savvy. So of course he would invent a few implements to assist him in combat should the need arise. Currently as of yet, he has only obtained the materials and supplies needed to create the first two implements on the list of technologies he will possess. More will be added as time moves on.
Sword of the Ruby Sun
One of the first implements crafted, this blade is not purely tech but it is not purely m. either but a combination of both. The Ruby Sun Sword is one of the more dangerous weapons in the arsenal of James Star as he forged it out of a unique material that seems to be like normal metal except the blade will never rust, dull, or break or require sharpening of any sort. Also when he wields it, the blade appears to be covered in some sort of Red Energy. The Sword of the Ruby Sun combines what he has learned of science and technology and chemistry over the last eight years with his skills with M. The tech of the blade is that it is laser sharpened.

Just a set of twin swords that are made similar to the sword of the Ruby Sun, but are completely m.based instead of technologically based. They may seem like tech due to the sheer number of properties James has imbued these blades with over the past eight years. They can never rust, dull or decay with the flow of time. Also these blades in his hands are a weapon unlike any other besides the sword of the ruby sun. They are made out of the same material.
