Considering the specs, it isn't much different from what the likes of Masiello recommended for fencing practice. So it checks out for the 1890s, and even before it. The main difference is the lack of curvature. Paul already confirmed he is working on a curved blade. Can't wait for those. They will be brilliant as replacement blades for the Hanwei Pecoraro/Radaelli hilts.
Yes, we are eagerly awaiting the curved blades. Had them pre-ordered when he tried to release them the first time, but then Russia destroyed the factories. - Peter
For those, who want to print the grip. I sliced it with 2mm wall thickness, 40% infill and the first and last cm solid filling. The printing takes a while with these settings, but it will increase mechanical endurance and you have some "flesh" you can sand/file to adjust the grip to the hilt.
