So You Wanna Buy an Authentic Katana?

There are basically two types of authentic Katana on the market these days:

  • Traditionally forged blades with a harder edge and softer spine and
  • Modern Monotempered blades forged much like the way a European sword is, with the same hardness all the way through (sometimes also called 'through hardened' blades)

Traditionally Forged

The hamon temper line of a traditionally forged blade

Monotempered

The plain but tough blade of a monotempered Katana

Some traditionalists and elitists argue that the latter type of sword are not authentic Katana at all (indeed, quite a few purists argue that unless a Katana is made in Japan and costs upwards of several thousand dollars, it is not authentic).

But for our purposes we are a bit more realistic and laid back, so let us define an authentic Katana by a sword that has the following qualities:

  1. It is hand made and hand forged - made from a suitable sword steel and properly tempered.
  2. It has a full tang under the hood - a proper nakago.
  3. It handles and cuts almost the same as the historical originals did - and is at least as strong (actually, most swords made these days are actually STRONGER!)..

So let's look at the two main types of functional Japanese style swords currently on the market.

Differences between the two main types of authentic Katana in a nutshell..

There are basically two factors that separate the two main types of authentic Katana currently on the market.

  • the types of steel used and
  • how it is tempered and hardened..

A traditional sword has been differentially hardened - that is to say that the edge of the sword is much harder than the spine, and this is done by applying a special clay treatment and quenching the blade so that the spine cools much slower than the edge.

Broken from heavy destructive testing, here you can clearly see how the hamon extends all the way through the blade and marks the harder edge section from the softer spine

The easiest way to identify if a sword has been differentially hardened is to look at the hamon - if the hamon is real,then the blade is much harder at the edge.

A NOTE ON FOLDED SWORDS

A folded sword does nothing to improve the quality of the blade - these days it is just a cosmetic feature (actually, most swords under $500 that are folded are actually WORSE off than if they were not.. Click here to bust the myth that folding a Katana actually makes it stronger or more functional)

The second type of sword is the contemporary one that has been monotempered - i.e. it was not clayed or differentially hardened but it is the same level of hardness all the way through (monotempered or through hardened).

True enough,there are sub types - such as swords that have been folded and swords that have been laminated, but the main point of differentiation is the hamon (after all, folding does nothing to improve the quality of a blade made from modern crucible steel, and a laminated blade is usually also differentially hardened, with the end result of lamination is the same as differential hardening - to make the edge harder and the spine softer).

Advantages and Disadvantages of the two Types

Most serious collectors of Japanese swords have at least one of each broad type of Katana in their collection. But many prefer one style over the other - so here is a quick and dirty guide to the advantages and disadvantages of each type so you can figure out where you should be focusing your search.

"Traditional Blades Cut With Minimal Effort while Contemporary Katana have an emphasis on toughness and durability"

The hardened edge of a traditional Katana simply cuts better for the simple reason that the harder the steel is, the easier it pushes aside anything softer than it (especially organic targets such as pork legs, tatami mats, bamboo etc - authentic Katana were specialized to cut targets that approximate human flesh and bone).

You can feel the difference, a Katana with a hardened edge kind of 'snips' through a target with minimal resistance, while a sword that is monotempered generally requires more muscle and force to go through the same target, and you can feel the extra resistance when you cut.

Conversely, a monotempered Katana can be used on a wider variety of targets because the edge is softer and more shock resistant - and because the edge and spine are the same hardness, will spring back to true when deformed or bent much like a medieval European sword, while a differentially hardened Katana will tend to stay bent..

You can see this demonstrated rather graphically in the video below.The first part of the video shows a monotempered 1060 carbon steel blade being belted against a steel pole with zero damage.While a blade made of tougher,harder 5160 that has been differentially hardened gets the edge chewed up by the same target..

And then it gets extreme - testing on a granite block and well.. The results speak for themselves.. (after all, even the best authentic Katana made in Japan will quickly meet its fate if pitted against granite!).

VIDEO: Breaking Swords so YOU don't have to..

Because of the extra durability of monotempered Katana, they are often recommended for beginners who may attempt to cut targets that even the best authentic Katana is not optimized for, and are more forgiving of bad technique.

However, just because they are not as tough does not mean that one should discount traditional blades..

Because when used on a target meant to approximate human flesh and bone, a traditional Katana simply cuts so much easier with minimal effort - it can be sharpened to a higher level than a monotempered blade (and keep that edge for much longer) and is,quite simply,the most authentic Katana of the two options.

Plus, a nicely done hamon temper line is true sword art at its finest.

Recommended Buys under $300

So if you have come this far, you should already have an idea of which of the two types of authentic Katana that you like the most is: if you like a cosmetically appealing blade that cuts targets with ease and is as close as possible to a genuine Nihonto costing several thousand dollars - then a traditional sword is for you.

If on the other hand you want a blade that can handle a wider variety of (sometimes unintentional) targets - then you should invest in a monotempered beater style blade.

Within each category,there are MANY swords to choose from - and it can be especially confusing for the beginner. So let's make it easy - and select what I feel are the best buys for each category for under $300.

The best monotempered blades under $300

Sunlight plays on the monotempered blade of a Ronin Katana Dojo Pro

It is a lot less complicated to make a monotempered sword - no claying, greater chance of surviving the heat quench and tempering - and so there are quite a few cheap options..

But if you want to get serious, our top recommended swords under $300 have to be those from Ronin Katana.

It was one of their Dojo Pro series that you saw in the video below, and while no sword is unbreakable (even the most authentic Katana made in Japan is going to end up broken on a granite block) they are extremely tough and able to take on a huge variety of targets.

But it is not just the blade that makes these swords so good - for overall,the materials used in the rest of the swords construction are head and shoulders above ANYTHING else under $300..

Conclusion

At the end of the day, which of the two main types of Katana available these days - traditional or beater - depends on your personal preference.

Some people,like myself,can appreciate both types.I like a traditional blade for how effortlessly it cuts light and standard targets, but I also enjoy the cool factor of a 'take on anything' beater.

Some dojos prefer to supply their students with monotempered beaters simply because they are so forgiving of mistakes, bad techniques and unintentional targets (stands, brick walls, concrete floors, etc) while others prefer the students learn the hard way and may need them to straighten out a traditional blade that took a set on a badly aligned cut.

There is no right or wrong answer - just what you prefer. And there are plenty of options for both..
