“Do Sar-Tiz” Knife 

Two-Edged Speedborn Knife 

Do Sar-Tiz is a handmade knife born in under two minutes—quite literally.
This uniquely designed dual-edged knife represents the spontaneous, raw, and intuitive design spirit behind NewStudiow’s early experimental era.

The story began in the summer of 2022 at the traditional bazaar of Zanjan. After failing to find an ironsmith for another project, we walked into Mr. Heydari’s workshop by pure chance. When he asked, “What’s your design?”, the sketch for Do Sar-Tiz was drawn instantly—right there, between the pages of his old notebook.

That fast gesture became a real object.
Sharp, minimal, and uncompromising, Do Sar-Tiz reflects the immediacy of an idea captured at the speed of inspiration.
