Jantz Supply Sword Making Kit
Jantz Supply has been a trusted name in bladesmithing materials for decades, and their sword-making kit reflects that pedigree. The kit includes high-carbon steel stock (typically 1084 or equivalent), handle material, basic fittings, and a hardware set. It is aimed at hobbyists who have done knife-making before and are ready to scale up to full sword geometry. The material quality is consistently high, and Jantz's customer support is genuinely helpful for first-time sword builders.
USAKnifemaker Blade Blank
USAKnifemaker specializes in pre-made blade blanks that are profiled, ground, and in many cases pre-hardened - ideal for builders who want to focus on fitting and handle work rather than stock removal. Their katana-style blanks are available in several steel grades and edge geometries. Buying a pre-hardened blank saves substantial time and bypasses the need for a heat-treating setup, making this the fastest path to a completed, functional sword.
Brownells Sword Handle Wrap Kit
Brownells' sword handle wrap kit focuses specifically on the tsuka (handle) construction - the part of katana building that most beginners underestimate. The kit includes ito wrapping cord in traditional cotton, rayskin (same) grip panels, and basic menuki hardware. The wrapping pattern for a katana is unique and takes practice, but Brownells includes a clear visual guide. A well-wrapped tsuka transforms the look and feel of any blade blank instantly.
Japanese Sword Handle Making Kit
This dedicated tsuka-assembly kit is purpose-built for authentic Japanese sword handle construction, including the ho wood core blank, pre-cut same panels, full-length ito cord in a choice of colors, and ornamental menuki. Everything is measured for a standard-length katana handle. Unlike general-purpose wrapping kits, this one is tuned specifically to katana proportions and traditional lacing patterns, making it the most useful for anyone building a finished, traditionally styled sword.
What matters most
Steel grade and hardness
Are the foundation of any katana build. For a functional sword, look for 1060-1095 carbon steel or 1084 equivalent - avoid mystery metal. If you are buying a blank, confirm whether it is annealed (soft, ready to grind) or already hardened. **Handle material compatibility** matters too: the tsuka must fit the tang precisely without slop, so always measure your blank's tang dimensions before ordering handle components. Finally, invest in a **quality ito** - thin, poorly made wrapping cord unravels under use and ruins an otherwise strong build.

Frequently asked
Forging a katana from raw steel requires a forge, anvil, grinder, and months of practice - it is a serious craft skill. However, assembling a katana from a pre-ground blade blank is achievable for a motivated hobbyist with basic woodworking tools. Kitting out with a quality blank and handle wrap kit is the most accessible entry point for most people.
You need a wood rasp or rotary tool to shape the tsuka core (magnolia or ho wood is traditional), rayskin (same) for the handle grip base, cotton or silk ito for the wrap, and menuki ornaments for decoration. A sharp knife, measuring tape, and patience are just as important as specialized tools. Most handle kits include all core materials.
Yes, but it requires either a propane forge or a heat-treating oven capable of reaching 1,475-1,500°F, plus a quench tank with canola or parks 50 oil. Home heat-treating is achievable but demands careful temperature control. Many hobbyists skip this step and purchase pre-hardened blanks, which can be ground and fitted without further heat treatment.
