Scarlet Dusk – Hand Forged High Carbon Steel Katana Sword
The flat of a well-ground 1060 blade has a particular quality under a work light – not mirrored, not matte, but somewhere between: a surface that shows you the geometry of the grind without flattering it, which is exactly what a practitioner needs to see.

Forged in Longquan
1060 carbon steel sits at 0.60% carbon – a deliberate position on the spectrum that prioritizes toughness without sacrificing the edge retention a working katana requires. At this carbon content the steel is substantially more forgiving under lateral stress than higher-carbon alloys; it will flex where a 1095 blade might chip under the same load. Oil quench and temper is the correct heat treatment for 1060: the quench rate is controlled enough to achieve the target hardness range across the full blade profile without introducing the brittleness that water quenching can produce in a blade this length.
The Scarlet Dusk (赤霞, Chì Xiá) is ground in shinogi-zukuri (ridgeline) geometry – the classical katana profile with a defined shinogi, the raised ridge that runs the length of the blade separating the flat from the beveled surface. This geometry is not incidental. The shinogi line stiffens the blade longitudinally, reducing flex during a committed cut, while the geometry of the bevel behind the edge determines how the blade enters and exits a target. On a 3.2 cm wide blade this proportion is orthodox and correct.
Weight, Balance, Draw
The 27 cm tsuka (handle) wrapped in cotton ito gives this katana a handle length suited to a two-handed grip with room to spare – your rear hand seats fully on the kashira end without crowding the leading hand’s position near the tsuba (guard). The cotton ito wrap is firm and slightly textured, not slippery when hands are dry, not abrasive when they are not. The green Aohada (bark wood) saya provides a clean, quiet draw with enough friction to hold the blade securely when inverted or jostled. The copper fittings at the tsuba and habaki (blade collar) add visual warmth against the blade’s surface finish and are more corrosion-resistant over time than zinc alloy alternatives.
Keeping It Sharp
1060 steel re-edges readily on a quality whetstone – work through 400 to 1000 grit to restore the edge bevel, then finish on a strop. Wipe the blade clean after every session and apply a thin coat of choji oil or mineral oil to prevent surface oxidation. The copper fittings will develop a natural patina over time; leave it, or polish lightly with a dry cloth if you prefer the bright finish.
