Overview

Tsunoda is a Japanese hand tool maker, and the RP-200 is a compact, light plier at 180 grams with PVC-coated handles, sized for precision work rather than heavy leverage tasks.

The low weight and PVC handle coating point to a plier meant for close, controlled work such as wire handling or small-parts assembly, where a lighter tool reduces hand fatigue over long sessions rather than raw clamping force.
