The 1045 High Carbon Steel has a 0.45% carbon content in its blade. This steel is relatively soft and easy to work with, resulting in it being more affordable. They are properly heat-treated and quenched resulting in a true battle-ready option for light-cutting practice targets, ideal for beginners.

The 9260 Spring Steel is a type of alloy metal that has a 0.60% carbon content with 2% silicon. The result is a very flexible and sturdy blade that has a high tolerance to bending even after a 90-degree twist. It has a higher rust resistance making it ideal for decoration and heavy-duty cutting tasks.

The 1095 High Carbon Steel has a carbon content of 0.95%. The high carbon content makes it very sturdy and durable with its heat treatment giving it the right level of flexibility. This makes it one of the most popular blade options due to its performance in cutting tasks and its ability to hold a razor-sharp edge.

The T8 steel has a carbon content of 0.80% and is a modern industrial tool steel known for its durability and strength. The T-series of metal are renowned for their toughness and durability. It excels at cutting performance tasks even when facing hard targets such as bamboo or tatami mats.

Damascus steel is made by pattern-welding two different metals together into one. It is ideal for decorative purposes, especially when polished. However, when properly heat-treated, it can also function as a real battle-ready sword.

The S5 Steel is known in the sword community as "shock steel" due to its ability to retain a sharp edge after rigorous and prolonged cutting activities. It contains the right mix of carbon, silicon, and manganese, giving it the perfect balance of flexibility and toughness. This makes it a modern, battle-ready blade ideal for tameshigiri (cutting training).

S7 Shock Steel is a very strong and tough type of steel used in making tools and swords. It's specially treated to handle a lot of stress and impact without breaking. This makes it perfect for cutting tasks, like in sword practice. Essentially, it's one of the best materials for making durable and reliable swords.

Wootz Steel is an exceptionally rare and difficult-to-produce type of metal. It is a blend of various blade materials, such as flexible wrought iron and sturdy carbon-rich iron. This blade features unique patterns due to the crafting process and can showcase distinct types of hamon (temper lines). Wootz Steel is known for its beauty and strength, making it highly prized among collectors and sword enthusiasts.

Crucible Steel, similar to Wootz Steel, is a rare type of metal made inside a crucible, a modern metal container heated to very high temperatures. It contains 0.65% carbon, providing an ideal balance of hardness and flexibility. Crucible Steel blades also have unique patterns, but their hada (surface pattern) is more delicate and finely divided than that of Wootz Steel. When properly heat-treated, Crucible Steel can function as a real battle-ready sword while retaining its decorative appeal.

LD Steel is a modern type of tool steel renowned as a battle-ready marvel in the sword community. It is a steel that is very hard to work with and to produce just right, making it exceptionally rare. This steel is renowned for its level of toughness and flexibility as well as retaining a sharp edge without cracks after abusive and rigid cutting tests.

The ZXN-275J is a type of modern spring steel that is ideal for very abusive tameshigiri (cutting tasks) against hard targets like bamboo or tatami mats. It is a modern marvel of a blade material that has the right level of hardness and toughness with a ductility of 275J making it able to bend without breaking.
