Topologist

Topologist is a American rigger.

Era: 2010s

RIGGER · TEACHER · PLATFORM CREATOR

US / North American rope-bondage educator and creator of Crash Restraint, also publicly identified as Chris. Crash Restraint's bio says he has studied rope bondage since 2007 and taught throughout North America since 2009, with a non-dogmatic approach combining Eastern and Western bondage, safety, reliable ties and adaptability to different bodies and play styles. His public technical impact includes the Somerville Bowline family, chest-loading takate-kote work, suspension-lift mechanics and safety / negotiation education. Current and archival sources frame him as an online-course creator and conference / workshop educator rather than a formal Japanese lineage figure.

Bakushi Map BETA

An interactive genealogy of bakushi and kinbaku — the Japanese rope traditions that grew from Edo-period hojōjutsu through twentieth-century SM magazines into today's global shibari scene.

People: 343

Each record is sourced from public material — Nawapedia, ShibariStudy, festival rosters, interviews, archived studio pages — and curated by a single researcher.

Beta — structure and interface are public; data is still being expanded and corrected.

How to read it

Vertical position is time: the 1800s at the top, the 2020s at the bottom. Cards are coloured by school or lineage; lines between them carry the relationship type:

deshi — direct apprenticeship
influence — peer study, mentorship
thinner colours — venue, magazine, production
card colour = school / lineage

Click a card to open its bio, antecedents and descendants. Filters in the top bar narrow by era, entity type, or relationship.

Caveats

Inclusion is selective: a person or studio appears only when there's enough public evidence to anchor them meaningfully. Missing birth years are deliberate — many practitioners don't publicise them. Errors and gaps will exist; corrections welcome at pussynawa@proton.me.
