Chain; band; rope; multi-segment style pipe/tube wrenches
These are often used for gripping/holding/unscrewing very large diameter objects e.g. oil filters
This type of grip/wrench rely on friction and a self-tightening design to grip large circular objects fairly evenly all the way around the circumference.
Chain wrenches are common, whilst variations are textile bands (see Britool wrench illustration) and multi-segments.
Uses: Oil-filter removal; holding pulleys whilst tightening locking bolt; general gripping of large round objects, sometimes irregular shaped.
