The LIANG-0235 listing describes a handheld forming tool for copper wire and etched sheet, with a non-slip grip, adjustable tension and a built-in measurement guide. Its description names 304 stainless steel. That makes the holding arrangement, rather than a general precision label, the feature to compare with a grooved ruler or plate fixture.
The seller gives copper wire 0.5–3 mm and 90–180 degree bends in its feature text, and describes a 1–10 mm bend-radius range in the longer description. Treat those as seller-stated receiving limits to confirm against the actual tool and wire, not a certified result or universal permission for metal stock. A claimed±0.1 mm accuracy is not adopted here.
Exact overall size also needs confirmation: 6.3 × 2.4 inches appears in the size/description, but another item field says 3.94 × 1.97 × 1.38 inches. The listing names ULTWAT as brand and manufacturer while the tool is named LIANG-0235. Check the actual model/package if that identity or the holding adjustments are decisive. ANSAI’s grooved ruler offers a simpler guide arrangement; JOYABEST instead supports sheet forming under an adjustable plate.
