Midareba Hamon Aikuchi Tanto

Midareba Hamon Aikuchi Tanto (Wavy-Tempered Short Sword with Aikuchi Mounting)

Description:
This is a 3D-printed Aikuchi Koshirae (guardless mounting) tanto (dagger) with a 20cm blade. The design faithfully replicates traditional Japanese sword elements:

• Hira-fuchi/Hira-kashira: collars at the handle’s  tip for minimalist aesthetics.
• Ko-zori: Subtle curvature optimized for thrusting and close-quarters combat.
• Midareba Hamon: A wavy, flame-like temper line along the blade, mimicking traditional clay-tempered steel.

Printing Notes:

• Blade Orientation: The blade must be printed vertically to preserve the hamon’s wavy texture.
• A1 Mini Limitation: The vertical blade exceeds the A1 Mini’s build volume. Use a larger printer.
• Supports: Minimal internal supports (non-visible post-processing).

Assembly Guide:

1. Adhesive Required: Bond parts using CA glue or epoxy.
2. Alignment: All components feature snap-fit guides to prevent misalignment.

3. Critical Marker: Align the red triangular marks on parts—the triangle always points toward the blade’s edge (see diagram).

The strength of 3D-printed knives cannot be guaranteed and they are suitable only for light-duty tasks, such as cutting paper or opening Amazon packages. Unless otherwise specified, all of my knife designs are intended for light-duty use only.
