Xinyi Wanjia

Xinyi Wanjia is a Chinese brand associated with fixed-resistance torsion-spring grippers and a large adjustable U-spring gripper. English-language information is scattered across retailer listings, collection records, videos, and grip-community discussions rather than a well-preserved official history.[1][2]

Fixed-resistance grippers

Documented examples include models marked 225, 275, 325, 400, 450, 550, 650, and 750.[3][4] These model numbers should be treated as product designations, not standardized closing-force measurements.

The higher-numbered models attracted attention in English-speaking grip circles during the 2010s. A 2017 GripBoard discussion of the 350 and related models includes photographs, measurements, and reports from owners.[5] In the same discussion, a measured 450 specimen was reported at approximately 302 lb RGC after its spread had changed with use. That is a measurement of one specimen, not a rating for every 450.

Adjustable model

Xinyi Wanjia also produced a large U-shaped adjustable gripper. Retail listings describe multiple handle positions, while a demonstration video identifies a 9 mm spring.[1][2] Moving the handles changes leverage and usable resistance, so an adjustable gripper's setting must be recorded for comparisons to be meaningful.

Identification and uncertainty

The name may appear as Xinyi Wanjia, XIN, or in translated marketplace titles. Packaging, handle markings, and seller descriptions are useful identification clues, but marketplace listings sometimes reuse photographs or translated specifications. GripperVault records provide photographs of known specimens, while GripBoard discussions preserve contemporary owner observations.

A complete production chronology and authoritative model catalog have not yet been located. This page therefore documents models supported by surviving examples and contemporary sources rather than presenting a speculative full lineup.
