Anime where the main character is a swordsman or uses a variation of the sword: Longsword, short sword, stiletto etc.

Cutout animation is a form of stop-motion animation usually made with paper or fabric cutouts. The technique was especially popular in Japanese animation before 1934 because cel animation used to be too expensive. Therefore pioneers of anime such as Noburou Oofuji and Yasuji Murata often used cutouts. Silhouette animation is considered a subgenre with its history going back to shadow plays. It is included in a separate stack.

These stacks are meant for cataloguing every stop-motion animation on Myanimelist. The list is the result of research by the Stop-Motion Animation Appreciation Society:

Stop-motion is a form of animation in which objects are manipulated little by little while each frame is shot separately. Puppet animation is the most common, but before 1935 cutout animation was also very common. Among other types are claymation, pixilation (now removed from the database), object and model animation. In this list also works using sand, charcoal or paint are included, since in the form they've been accepted to MAL, they also include gradual manipulation and shot by shot filming.
