The eight tantos shown here measure 50 cm overall, about 19.7 inches, with a 33 cm blade, about 13 inches. Our four wakizashi models measure 80 cm overall with 52 cm blades. That is a useful difference to keep in mind when choosing a piece for a shelf or display cabinet.
Measure the space with both the sword and scabbard in mind. A display with the blade drawn needs room for the saya beside it, as well as the stand. For a gift, check the recipient's available space and preferred colors before deciding between a tanto, wakizashi and a full-size katana.
These modern tantos have longer blades than the under-30 cm definition used for traditional Japanese daggers. Use each product's measurements, rather than the category name alone, to judge the size you will receive.
Hagane is the Damascus option. Aoto, Seiryu, Shirayuki, Enzan, Aozora and Byakuen list T10 tool steel. Their colors and fittings differ even when the steel name is the same. Our katana steel guide explains the terms you will see in the specification tables.
Hamon details and colored finishes vary by model. A blue surface or a wave pattern alone does not identify how a blade was hardened. Compare the specifications and close-up photos together, especially if the steel or hamon is the part you care about most.
Keep the blade dry, avoid touching the steel with bare fingers and follow the model's care instructions. A soft cloth is the right place to start for lacquered scabbards. Avoid abrasive polish on artwork and colored blade finishes.
