What steel is used in these white ninjato blades?

Most pieces in this collection are forged from T10 tool steel, a high-carbon alloy with roughly 0.95–1.04 percent carbon and added tungsten. The tungsten increases wear resistance and helps the blade hold a well-defined edge geometry after differential hardening. During the clay-temper process, the spine is coated with a thicker clay layer than the edge before quenching, producing a genuine hamon and giving the blade two distinct hardness zones — typically around HRC 58–60 at the edge and HRC 38–40 at the spine. This combination makes T10 one of the most respected steels for hand-forged collectible swords because it balances hardness with enough flexibility to resist fracture.

What steel is the ninjato blade made from?

The blade is forged from manganese steel with a full-tang construction and hand-finished to a chrome polish. It features a straight profile with a chisel tip, worked by hand for edge refinement and surface finish.

How should I store and maintain a collectible ninjato?

Carbon and manganese steel blades require periodic attention to prevent surface oxidation. After handling, wipe the blade down with a clean, lint-free cloth to remove any fingerprint oils, then apply a light coat of camellia oil or a dedicated sword oil from tip to habaki. Store the piece horizontally on a stand or in its saya, in a low-humidity environment — silica gel packets inside a display cabinet help significantly in coastal or high-humidity climates. Avoid storing blades in leather-lined enclosures for extended periods without oiling, as some leather treatments can introduce moisture and accelerate patina. T10 clay-tempered blades benefit from the same routine but are especially worth protecting given the craftsmanship invested in the hamon.

What steel types are used in this collection?

This collection includes pieces in manganese steel, 1045 carbon steel, 1095 carbon steel, and T10 carbon steel — each with distinct characteristics worth understanding before choosing. Manganese steel is valued for its toughness and resistance to surface stress, making it a stable option for long-term display. Its blades are often finished with black or blue coatings that amplify the sword's dramatic appearance. 1045 carbon steel is a mid-range option with reliable hardness, while 1095 offers slightly higher carbon content and a harder edge. T10 is considered a premium tool steel that, when clay-tempered, produces a visible hamon — the wavy temper line running along the blade that is one of the most prized visual details in Japanese sword collecting. The T10 ninjato in this collection features a genuine hamon alongside a dragon-engraved silver saya, making it the most technically distinguished piece in the lineup.

What steel is the Fujitora sword blade made from?

Updated Feb 2026

This Fujitora ninjato uses a 1045 carbon steel blade with a chrome-finish surface, hand-finished edge, and hardness rated at 60 HRC. The full tang construction runs through the entire 10.2-inch rosewood handle for structural integrity.
