How to carve patterns Part4 ~Seigaiha and Shippo-Tsunagi ~

how to carve

In this tutorial, we’ll explore how to carve two elegant and flowing patterns:

  • Seigaiha (Blue Ocean Waves)

  • Shippo-Tsunagi (Seven Treasures / Interlinked Circles)

Unlike previous patterns where we mostly used triangular, flat, and sharp chisels, this time we’ll make good use of a shallow round chisel, which is ideal for smooth curves.

Preparation

Use carbon paper to trace the Seigaiha and Shippo-Tsunagi designs onto a postcard-sized wooden board.
You can download the sketches from here: [PDF of Seigaiha and Shippo Tsunagi].

1. How to Carve Seigaiha (Blue Ocean Waves)

Step 1

Use a triangular chisel to carve the areas above the black lines in the sketch.

Step 2

Next, use a sharp chisel to make incisions at both ends of the lines.
Carve a little deeper toward the tips.

Step 3

Use a flat chisel to carve a slope that intersects with the points where you made the incisions.

Once you’ve carved the slopes, the surface should start to show subtle height differences between wave segments.

Step 4

Some lines may have become faint, so re-carve the outlines with the triangular chisel.

Step 5

Use a shallow round chisel to carve the curves of the waves.
Work slowly and carefully, ensuring the waves are smooth and not uneven.

Final Touch

Use a combination of tools—flat chisel, sharp chisel, shallow round chisel, and triangular chisel—to clean up the carving.
Remove any rough edges or uncut areas for a polished finish.

2.How to Carve Shippo-Tsunagi (Seven Treasures Pattern)

Step 1

Start by using a triangular chisel to carve lines that connect the intersection points of the overlapping circles.

Step 2

Use a shallow round chisel to carve elongated semi-circular shapes, starting from the line-carved areas.

Adjust the horizontal angle of the chisel to change the thickness of the lines:

  • To carve thin lines, hold the chisel more upright (obtuse horizontal angle).

  • To carve thick lines, hold it flatter (sharper horizontal angle).

 

Step 3

As with Seigaiha, ensure that the curved surfaces are even and smooth when you're done.
