When you start cutting a piece of wood, do you ever feel like the saw blade won't stay stable, or it wanders away from your marked line?

If you have experienced this, you are not alone. The good news is that by learning a few simple techniques for starting a cut, your woodworking will become incredibly smooth and precise.

In this guide, we will show you the fundamental points for starting a clean cut with a Japanese saw, along with a helpful video tutorial.

3 Golden Rules for a Smooth Start

1,Choose a Saw with Fine Teeth

For beginners, we highly recommend using a saw with a fine tooth pitch (higher TPI). Finer teeth are much less likely to catch or snag on the wood fibers, making it much easier to start your cut exactly where you want it.

2. Secure Your Wood Completely

Always use clamps to secure your wood tightly to your workbench before you start. If the wood shifts even slightly, the saw will become unstable, making an accurate cut impossible.

3. Start at the Corner (Edge)

When cutting lumber, the basic rule is to start by placing the blade against the far corner (edge) of the wood. Placing the blade completely flat on the top surface and trying to start cutting is not recommended. The blade will easily slip, causing your starting point to shift.

Step-by-Step: Using Your Thumb as a Guide

The most common struggle for beginners is "getting the blade to stay on the mark." The best solution for this is to use your thumb as a guide block.

1, Place the thumbnail of your non-dominant hand exactly next to where you want to start the cut.
2, Lightly rest the bottom side of the saw blade against the side of your thumbnail.
3, Double-check that the blade is perfectly aligned with your marked line.
4, Make a very tiny, light cut into the corner, then lift the saw away.
5, Repeat this gentle motion a few times to create a shallow starter groove (kerf).

⚠️ Safety First: When using your thumb as a guide, always tuck your first knuckle slightly inward. Make sure the teeth of the blade are resting against the nail, never the soft pad of your finger, to avoid any risk of injury.

Since there is no deep groove yet, the blade can easily wobble left and right. Therefore, pull very slowly and with extremely light pressure at first.
(Note: If you feel more comfortable pushing lightly to establish that first tiny groove, it is perfectly fine to do so.)

Utilizing the "Pull-Stroke" Advantage
Once you have established your starter groove, gently lower the angle of the saw blade. By laying the blade down slightly, you create a longer groove across the surface of the wood. This extended groove acts as a track, keeping the saw perfectly stable.

Now, use the full length of the blade and gently move it back and forth along your line.
This is where the magic of the Japanese saw happens: Because it cuts on the pull stroke, the blade is placed under tension, keeping it naturally straight. Unlike Western push saws that can buckle or bend, a pull saw practically guides itself.

Just apply light pressure as you pull, and relax your grip as you push it back forward. Never force or push the saw hard, as this can cause the thin blade to bend.

Summary

・To start your cut cleanly and accurately, remember these key points:
・Use a saw with fine teeth.
・Clamp your wood securely.
・Start slowly from the corner to make a groove.
・Let the saw do the work—don't apply too much force.

By mastering these basics, your woodworking will become dramatically easier and more enjoyable. Everyone struggles at first, so please watch the video and give it a try!
