Staedtler 770: A YouTube Review of the 34-Year Reissue

Japanese stationery YouTuber "Seasar Stationery" (1.05 million subscribers) reviewed Staedtler's drafting mechanical pencil, the "770" reissue. This article summarizes the content of that video.
About the product
The "770" is a reissue of the "Mars Micrograph F 770," sold from 1978 to 1990, brought back after 34 years. Released in September 2024, it costs 1,540 yen (tax included) and is made in Japan. It comes in four lead sizes: 0.3mm, 0.5mm, 0.7mm, and 0.9mm.
Specs
It weighs a light 10.8g, measures 139.6mm long, with a relatively thin grip diameter of about 8.5mm. The center of gravity is low, about 63mm from the tip, and it has a fixed 4mm guide pipe.
What the video says
The video praises how the light body and low center of gravity make it easy to write smoothly, and notes the pencil feels stable with almost no wobble during writing despite the resin body. On the other hand, it points out that the thin grip makes the clip prone to touching the fingers, and that the price is a bit high for a resin drafting pencil.
