Metal tea utensils range from mass-produced items stamped out in an instant by press machines to "hand-crafted artisanal pieces" shaped by a craftsman striking the metal thousands or tens of thousands of times with a hammer and chisel. Though they may look similar at first glance, the sense of weight and the way they reflect light when held in the hand are entirely different. Here, we explain the techniques and connoisseurship behind *senkoku* (chasing and engraving).
1. What is Senkoku (Chisel Engraving)?
Senkoku is a traditional Eastern metalworking technique in which a steel chisel (tagane) with a specialized tip is placed against a metal plate and struck with a small hammer to carve out patterns, creating three-dimensional relief or intricate textures.
2. How to Distinguish Between Machine-Pressed and Hand-Forged Items
| Comparison Item | Mass-Produced Machine-Pressed/Cast | Artisanal Hand-Forged/Hand-Engraved |
|---|---|---|
| Surface Texture (Hammer Marks) | Uniform, regular patterns with soft boundaries | Depth and angle vary with each strike, creating organic shadows |
| Engraving Edges | Rounded and dull, resulting in a flat appearance | Sharp chisel cuts that create strong contrast between light and dark |
| Feel and Weight | Thin, lightweight, and often hollow on the underside | Solid, heavy metal with a tactile quality that feels natural to the touch |
3. The "Artisanal Fluctuations" Inherent in Tools
Hand-crafted metalware possesses subtle, natural "fluctuations" absent in perfectly geometric, symmetrical pieces. It is these very nuances that create soft, warm shadows under candlelight or ambient lighting.
The three-dimensional forms seen in SEKIMONO's works (such as the Golden Toad and Auspicious Lion) are created through made-to-order production, with each piece finished by a craftsman’s chisel.
The stories behind the motifs expressed through hand-chiseled engraving are explained in our guide to the meanings of auspicious patterns in Chinese tea ware.
