Fit the outline to your hand
The broad B looks easy to hold in a photograph. Its measurements are more informative when traced onto paper: close your hand around that outline and see where your thumb and fingertips meet. In Amazon comments shown on the B listing, one reviewer liked the hand fit while another tired of gripping a small tool. The listing can combine shapes, so neither verdict guarantees a fit.
| What changes | B stainless steel gua sha scraper, 5.11 × 3.14 in | Sidekick Curve Muscle Scraper |
|---|---|---|
| Contact material | Stainless steel | Handmade Bian stone |
| Edge description | Double-beveled | Rounded stone edge |
STICKON gives its B a double-beveled steel edge and a footprint of 5.11 by 3.14 inches. Sidekick describes the Curve as its softer-edged, handmade Bian stone option.
The edge is a separate decision
Stone and steel behave differently if dropped and feel different against a hand. Sidekick specifically describes a rounded stone edge; STICKON identifies a bevel worked from both faces. Neither description quantifies pressure or establishes a treatment outcome. Avoid treating a visible skin mark as proof a session worked. For equipment used professionally, product-specific care and local practice requirements also belong in the decision.

Our recommendation
Choose B if its measured steel outline fits your grip. Choose the Curve when you specifically prefer a rounded stone working surface and can protect the tool in storage.
