Hand Saw Series - Japanese Saws
posted on December 29, 2010 by Ralph Bagnall

Over the last ten years or so, Japanese style saws have become widely available in the US market, so I thought I would discuss them as part of this handsaw series. Western style saws cut on the push stroke, where as Japanese style saws cut on the pull stroke.

The big difference this makes is that Japanese saws have relatively thin blades compared to their Western counterparts. Western saws need to be stiffer to resist bending when cutting. Since the Japanese saw cuts on the pull stroke, the resistance of the cutting action actually pulls along the blade length, helping to keep it straight. As a result, the blade can be thinner and the kerf narrower.

On inspection, you’ll also notice that the shape of the teeth is also quite elaborate, although many western saws (like the “Classic Handsaw” I profiled in an earlier post) are adopting a similar tooth geometry. Because the teeth tend to be small and fragile, they are specially hardened, which you can see in the discoloration of the teeth.

Almost any saw you need can now be found in a Japanese style as well as Western. While I personally like and favor Japanese style saws, they may not always be the first choice. There is a Japanese style keyhole saw for cutting curves, but a Western style coping saw has an external frame allowing a far narrower blade that can cut much tighter circles. Stiffer Western saw blades with longer lengths also lend themselves to resawing wide boards. Keep in mind too that the complex tooth grind on Japanese saws is virtually impossible for a home woodworker to sharpen, and the hardening process makes them more likely to break if an obstruction is hit when sawing.

Where these Japanese style saws shine is in the fine detail work that I typically grab a handsaw to do. The thin kerf and very fine teeth make accurately cutting dovetails quick and easy.

I also prefer these saws for edgebanding and other trimming tasks. A good starter set usually has a single handle with a crosscut and rip blade. I like this type for working on the jobsite. They are compact and travel better than comparable Western saws.

Japanese style saws can be a very useful addition to your toolbox, and are always a pleasure to use. They represent an alternative choice for the tasks you perform around your home and shop.

    How do you go about choosing one? I tried to buy one at the local Rockler a while back and the employee thought I was crazy. He didn't know anything about them and kept asking why I didn't just use a power tool.

    I am surprised and sorry that you had that experience at a Rockler store, my experiences have always been good there.

    It can be tough choosing the right saw since the names are all unfamiliar! So here are the most common names and what they mean:

    Dozuki- is a backsaw, meaning it has a reinforcement along the spine for stiffening. Typically, these are dovetail/detail saws.

    Ryoba- has a two sided blade, with one side for cross cutting and one for rip cutting.

    Kaeba- has a changeable blade. The set I am using in the blog post is a Kaeba. It comes with a rip blade and a separate crosscut blade that both fit into one handle.

    I hope this helps you in choosing a saw for your needs.

    Wouldn't want to be without one for either finish work or woodworking. They work well in hardwoods as well as softwoods and are quick, concise with no setup time. Use them for everything from cleaning up corners to making a fine cut in fitting pieces. Getting a precise cut with these saws is easy; they're shortfall may be in cutting sharper curves where a coping saw would be best.
