Its shallow-angle blade can be raised through the bed in stages, allowing a cut to progress gradually. Hackaday’s Dave Rowntree describes the build by JSK-koubou as an all-metal tool made without CNC equipment.
How the guided pull saw works
Unlike a conventional handheld pull saw, this design holds the blade in the tool bed and moves the workpiece. The blade sits at a shallow angle. Raising it incrementally through the bed lets the maker deepen the cut progressively rather than exposing the full blade height at once.
That arrangement makes this a hand-operated guided saw, not a powered circular saw or a standard pull saw used by hand. The guide and bed constrain the blade relative to the workpiece; the operator supplies the cutting motion by pulling the material across the blade.
What the build is made from
Rowntree describes JSK-koubou’s saw as an all-metal construction assembled from off-the-shelf components and thick aluminium alloy plate cut by hand. The article says the maker used no CNC equipment. It links a three-part build video series, but the written account does not provide a full parts list or build dimensions.

#1 Best Overall
- An Idea Gift for Woodworker, Carpenter and Craft Man
- Optimal Blade Size: Through numerous manual tests, We found that the 6" Japanese saw blade is the ideal size for precise cutting, enabling easy flush and finish cuts.
- Durable and Flexible Saw Blade: The hand saw blade is made of SK5 high-carbon steel. The Japanese pull saw teeth are processed by a high-frequency hardening machine imported from Japan, and the hardness can reach HRC60-63 degrees.
- Double Edged: One side of Japanese hand saw is 17 TPI for cutting hardwood, and the other side is 14 TPI for cutting softwood. Also can seen as Rip cut and Cross cut.
- Hardened 3-Edge Teeth: The hand saw has three-sided grinding gear design, sharp edge, faster chip removal, and smoother cutting.
The blade is the uncertain part
The blade is the design’s unusual component and may be difficult to source. Rowntree tentatively suggests it could be a spare blade for a commercial guide saw available in Japan, but does not confirm its identity. The article does not establish a specific make, model, or replacement blade that fits this DIY tool, so a Japanese pull-saw blade should not be assumed compatible.
How it differs from other woodworking saws
| Tool type | What moves | What the available description establishes |
|---|---|---|
| JSK-koubou’s DIY guided saw | The workpiece moves across a fixed blade. | Hand-operated; blade height can be raised progressively. No measured performance comparison is reported. |
| Conventional handheld pull saw | The saw moves through a stationary workpiece. | A related hand-tool category for fine woodworking, not an established replacement blade source for this build. |
| Powered circular saw | The saw’s powered blade moves through the workpiece. | A different tool format; the DIY build is not described as powered. |
Commenters on the Hackaday article compare the design with the commercial Bridge City Jointmaker Pro and describe this general class of tool as suited to fine joinery and small or delicate work. Those are commenters’ observations, not manufacturer specifications or independently measured findings. The article supplies no evidence that this saw is intended for sizing large stock or that it outperforms other saws.
Rank #2
- DOUBLE-EDGE JAPANESE PULL SAW: This japanese hand saw has rip teeth on one side for cutting with the grain, and crosscut teeth on the other side for cutting across the grain. A great general-purpose saw for cutting stock down to size as well as cutting large and medium sized joinery.
- PREMIUM HIGH-QUALITY COMPONENTS: Featuring a dark brown solid wood handle made of Wingnut (in the walnut family) with brass components. This japanese hand saw combines beauty and performance, delivering both aesthetic appeal, fast & accurate cutting, and a smooth professional finish.
- ACCURATE & EFFORTLESS CUTTING: Cuts on the pull stroke which allows for a thin narrow-kerf blade and lightweight design, this saw is razor sharp and provides a smooth, easy cutting experience – perfect for all ages and skill levels.
- MADE IN JAPAN: Handcrafted in a historic Japanese city by skilled artisans with over 100 years of saw manufacturing history and innovation. This pull saw reflects a heritage of meticulous craftsmanship, history, and quality. Known worldwide for excellence in woodworking tool manufacturing.
- DURABLE JAPANESE STEEL FOR PRECISION CUTS: Made from high-grade Japanese steel, this saw maintains long-lasting sharpness and provides clean precision cuts in soft and hardwoods.
What the article does—and does not—confirm
The account supports the basic design, materials, and hand-built approach, but it does not report cutting tests, accuracy measurements, safety testing, or a verified blade source. Its three-part build videos may show more construction detail, but the written article alone is not a complete fabrication plan.

Rank #3
- JAPANESE STYLE PULL SAW: This product is a “Pull Saw.” Most people are used to European saws, called “push saws,” which cut through a pushing motion. On the other hand, Japanese saws cut materials via pulling and are called “pull saws.” In comparison to “push saws,” this Japanese product is lighter in weight, requires less power, and results in a cleaner edge.
- JAPANESE STEEL: All SUIZAN Japanese saws consist of top quality Japanese steel. The high-quality steel makes razor sharp cuts.
- MADE IN JAPAN: All SUIZAN woodworking tools are manufactured in Japan by Japanese master craftsmen. The whole process of making these tools are completed in one of Japan’s towns known for its craft-making tradition with a history of over 100 years.
- DIVERSIFY YOUR WOODWORKING LIFE: No matter if you are a master or a beginner, using traditional Japanese-style saws gives you a brand new experience and lets you make a wider range of woodworking products, thus changing your life!
- For Rip & Cross Cut, Blade Length: 9.5"(240mm), Blade Thickness: 0.02"(0.5mm), TPI: 9&15(1.67mm), Kerf Width: 0.03"(0.8mm), Overall Length: 23.2"(59cm), Since each handle is individually wrapped by hand by craftspeople, its appearance may vary from one to another.
