Did you know that Japanese saws feature two distinct types of teeth: one for cross cutting and one for rip cutting?
If you use the wrong teeth for your cut without understanding the difference, you might experience:
・Poor cutting performance and binding.
・A rough, splintered cut surface (tear-out).
・Unnecessary damage or premature wear to the blade.
To get the absolute best performance out of your tools, let's start by understanding the specific role of each cut.
What is a Cross Cut? | "Severing" the Wood Grain
A cross cut is a cut made perpendicular (across) the wood grain—for example, when you are cutting a long board to make it shorter.
The teeth on a cross-cut blade work like a row of small knives, with each tooth sharpened alternately. This "staggered" arrangement allows the blade to cleanly cut through wood fibers from both sides simultaneously.
Characteristics of a Cross-Cut Blade:
・Slices cleanly across the growth rings.
・Requires a relatively delicate and smooth pull stroke.
・Leaves a beautifully clean, smooth finish.
👉 Pro Tip for Angled Cuts: When making a miter or angled (diagonal) cut, the blade is essentially cutting across the wood fibers. Therefore, the cross-cut blade is always the correct choice for angled cuts!
What is a Rip Cut? | "Chiseling" Along the Wood Grain
A rip cut is a cut made parallel (along) the wood grain—for example, when you are splitting a wide board lengthwise into narrower strips.
Instead of slicing, the teeth on a rip-cut blade feature flat, chisel-like tips.They are designed to carve and scoop out the wood fibers as you pull.
Characteristics of a Rip-Cut Blade:
・Cuts highly efficiently along the fibers.
・Features deep gullets (the spaces between the teeth) to quickly clear out large amounts of sawdust.
・Removes a significant amount of wood with each stroke, allowing you to cut much faster with every pull.
Because it works with the grain rather than against it, rip cutting generally requires less physical effort than cross cutting.
Two Saws in One | Ryoba (Double-Edged Saw)
The SUIZAN Ryoba saw brilliantly combines both a cross-cut and a rip-cut blade into a single hand tool.
While the blades are positioned on opposite sides (top vs. bottom relative to the logo), the easiest and most foolproof way to tell them apart is simply by looking at the teeth:
・Fine, densely packed teeth: Cross-Cut side (Teeth below the logo)
・Larger, widely spaced teeth: Rip-Cut side (Teeth above the logo)
This holds true for our 9.5-inch (240mm) model as well as all other Ryoba saws. If you observe the edge closely, the difference in tooth shape and spacing is unmistakable.

The Versatile Precision Tool | Dozuki (Back Saw)
Our Dozuki saws (available in 7-inch and 9.5-inch), known for their stiff spine (back), offer a unique advantage.
Unlike many traditional Western back saws that are strictly for cross cutting, SUIZAN Dozuki saws feature specially designed Universal Teeth. This means a single Dozuki blade can flawlessly handle:
・Cross cuts
・Rip cuts
・Angled/Diagonal cuts
Because of this versatile tooth design and the rigid spine, you can achieve incredibly stable and precise cuts (perfect for complex joinery like dovetails) without having to constantly worry about the grain direction.

The Right Blade Makes All the Difference
When it comes to cross cut vs. rip cut, it is never a matter of "which blade is better," but rather "which blade is right for the job."
By properly understanding the unique features and distinct roles of your Japanese saws and choosing the right teeth for the wood grain, you will protect your blades, drastically improve your cutting efficiency, and ultimately make your woodworking experience much more comfortable and enjoyable!
