Tell us about yourself!
We used to make a plane of similar design in high school. We would fold the paper in half, on the diagonal, so the fold ran the paper between the opposite corners. Then you give it some weight by folding it every 1 cm or 1/2 inch until you got the weight you wanted for the leading edge, like yours. Tuck the long ends into each other and you were done. We called them "Pope Hats" or "Catholic Freedom Fighters". The christian brothers who taught us had a laugh.
I'm a repair tech for medical equipment. Went through a whole 5S (workplace organisation process thing) recently. I was in charge of doing the tooling (organisation, purchasing, storing etc) so I did this to the sockets and wrenches. My boss didn't like it. The techs loved it. The boss threw a fit and had me clean it all off the tooling. When he retires, it's the first thing I'm doing. Some folks will never change...lol.
