I decided to try to craft something again. I just had to pass the festival and I decided to be there as the Talon from the League of Legends. I made a blade for him. I was advised to use expanded polystyrene as material. In general, I did it but had to go through many difficulties due to lack of tools. I applied the contour of the parts to the sheet and then cut it with a clerical knife as it needed accuracy. This hellish labor in a few minutes numb hand. From below I will add a photo of the process.
