Ever picked up a Japanese saw and felt it work differently from the ones you’ve used before? It doesn’t push - it pulls. And that’s not a mistake. It’s by design. If you’ve ever tried using one and felt like you’re fighting the tool, you’re probably pushing it like a Western saw. Stop. Let it do the work. Japanese saws cut on the pull because that’s how they’re built to cut - cleanly, precisely, and with far less effort.
How Japanese Saws Are Built Differently
Western saws have thick, rigid blades held under tension by a steel frame. They’re made to push through wood, relying on brute force. Japanese saws? Their blades are thin, flexible, and held taut only when you pull. The teeth face toward the handle, not away from it. That’s why you can’t push them - the teeth would bend or snap.
The blade thickness is a big deal. A typical Western handsaw blade is 0.8mm to 1.2mm thick. A Japanese pull saw? Often under 0.4mm. That’s half the thickness. Less material means less friction. Less friction means less resistance. And because you’re pulling, your body weight naturally helps drive the cut forward. You’re not forcing the blade - you’re guiding it.
Why Pulling Makes for Cleaner Cuts
When you push a saw, the blade bends slightly under pressure. That flex causes the cut to wander. You get tear-out on the far side of the wood, especially in softwoods or when cutting across the grain. Japanese saws don’t have that problem. Pulling keeps the blade under constant tension. The teeth bite cleanly into the wood without flexing. You get a straighter, smoother cut - even in dense hardwoods like maple or oak.
Try this: Cut a piece of pine with a Western saw. Then cut the same piece with a Japanese pull saw. You’ll notice the difference immediately. One leaves fuzzy, splintered edges. The other leaves a surface so clean you can skip sanding. That’s why carpenters in Japan have used these tools for centuries - they don’t need power tools to get precision.
The Role of Tooth Design
Japanese saws don’t just pull - they cut differently because of their teeth. Most have a triangular, razor-sharp profile with a high tooth count per inch (TPI). A typical Japanese pruning saw might have 10-14 TPI, while a Western equivalent might have only 6-8. More teeth mean each tooth removes less material. That reduces the chance of tearing wood fibers.
Some Japanese saws even have different tooth patterns on the same blade. The front third might be designed for cross-cutting (cutting across the grain), while the back is for rip-cutting (cutting along the grain). You get two tools in one. And because the teeth are hardened and sharpened to a fine edge, they stay sharp longer. You don’t need to sharpen them every few weeks.
Why This Matters for Pruning
If you’re pruning fruit trees, shrubs, or ornamental plants, precision matters. A rough cut invites disease. A jagged edge doesn’t heal well. Japanese pruning saws - like the Japanese pruning saw is a specialized pull saw with fine teeth designed for clean cuts on live wood - are made for exactly this. Their thin blades let you get into tight spaces where a bulky Western saw won’t fit. You can make a cut right at the branch collar without damaging the trunk.
Try pruning a thick branch with a Western saw. You’ll likely have to make multiple passes. With a Japanese saw, one smooth pull does the job. You don’t need to saw back and forth. You don’t need to force it. Just position the blade, pull gently, and let the teeth do the work. It’s less tiring. It’s faster. And your plants recover better.
Myth: Pull Saws Are Weak
People assume that because Japanese saws are thin, they’re fragile. They’re not. The thin blade is actually stronger in tension than a thick one is in compression. When you pull, the blade is pulled tight against the frame. It doesn’t flex. When you push, the blade buckles. That’s why Japanese saws can cut through 6-inch branches without breaking - they’re designed to handle load in one direction only.
They’re also lighter. A full-size Japanese pruning saw weighs about 150 grams. A comparable Western saw? Over 300 grams. That means less fatigue during long pruning sessions. If you’re working with multiple trees, that adds up.
When Not to Use a Japanese Saw
They’re not magic. Don’t use them for heavy-duty log cutting or demolition. They’re not built for that. If you’re felling a tree or cutting firewood, stick with a Western bucksaw or chainsaw. Japanese saws shine in fine work: shaping branches, trimming hedges, pruning roses, cutting bamboo, or making joinery cuts in woodworking.
Also, avoid using them on green, wet wood if it’s very thick. The blade can clog with sap. Keep it clean with a quick wipe after each use. A little oil on the blade once a season keeps it from rusting.
How to Use One Correctly
- Hold the saw with a relaxed grip - fingers wrapped lightly around the handle.
- Position the blade at the start of your cut. Don’t force it in.
- Use a smooth, steady pull. Let the teeth engage naturally. Don’t push.
- Let the weight of your arm guide the cut. Don’t press down.
- Use short, controlled strokes for precision. Long strokes work too, but only if the blade is fully supported.
Practice on scrap wood first. You’ll feel the difference in how little effort it takes. That’s the point.
What to Look for When Buying
Not all "Japanese saws" are created equal. Some are cheap knockoffs with dull teeth or flimsy handles. Look for:
- Blade thickness under 0.4mm
- Teeth per inch (TPI) of 10 or higher for pruning
- Handle made of hardwood or durable plastic - not cheap rubber
- Blade made of high-carbon steel - not stainless steel (it doesn’t hold an edge as well)
- Brand reputation: Nakaya, Kurimoto, or Izumi are trusted names
For pruning, get a 150mm to 200mm blade. That’s the sweet spot for most garden work.
Why This Tradition Still Works Today
Japanese tools didn’t evolve because of technology. They evolved because of efficiency. Centuries ago, craftsmen had to make the most of limited materials. Thin blades meant less steel. Less steel meant less cost. Less effort meant less fatigue. That’s why they designed tools to work with the body, not against it.
Today, that same logic applies. Gardeners want tools that reduce strain, last longer, and deliver better results. Japanese saws do all three. They don’t need electricity. They don’t need batteries. They don’t need sharpening kits. Just a little care, and they’ll outlast your Western saws by decades.
Final Thought: It’s Not About the Tool - It’s About the Motion
Using a Japanese saw isn’t about buying a fancy gadget. It’s about changing how you move. Pushing is force. Pulling is flow. Pushing tires you out. Pulling lets you work longer with less strain. That’s why gardeners in Japan, who’ve used these tools for generations, rarely complain about back pain or wrist fatigue.
Try it. Swap your push saw for a pull saw. Cut one branch with each. Feel the difference. Then ask yourself: Why did we ever stop using tools that work with our bodies - instead of against them?
Do Japanese saws need sharpening?
Yes, but less often than Western saws. Because the teeth are harder and the blade is thinner, they hold an edge longer. Most gardeners sharpen their Japanese pruning saws once a year or every 20-30 hours of use. Use a fine triangular file designed for Japanese saw teeth - don’t use a regular saw file.
Can I use a Japanese saw on metal or plastic?
No. Japanese saws are designed for wood only. The teeth are too fine and brittle for metal or hard plastics. Using them on these materials will quickly dull or chip the teeth. Stick to wood - that’s where they excel.
Are Japanese saws good for beginners?
Yes, if you’re willing to learn the motion. Many beginners think they’re harder because they’re different. But once you stop pushing and start pulling, they’re actually easier. They require less strength and produce cleaner results. Start with a small pruning saw and practice on softwood.
Why are Japanese saws more expensive?
They’re hand-forged, often in small workshops in Japan, using high-carbon steel and traditional methods. The blade is precision-ground, and the handle is shaped for balance. You’re paying for craftsmanship, not mass production. A good one lasts a lifetime - so it’s a long-term investment.
Can I use a Japanese saw for pruning in winter?
Absolutely. In fact, winter is ideal. Trees are dormant, and the wood is drier, making cuts cleaner. Just make sure the blade is clean and lightly oiled before and after use to prevent rust in cold, damp conditions.
Next Steps: Try It Out
Don’t just read about it - test it. Borrow a Japanese pruning saw from a friend, or pick up a basic one for under £20. Cut a single branch. Feel how little effort it takes. Notice how clean the edge is. Then go back to your old saw. You’ll see why this ancient design still wins today.
