Reddit mentions of Gyokucho Razorsaw 9-1/2" Double Edge (Ryoba) for Hardwoods

I purchased 2 different saws, one with a rigid back for dovetail. And then purchased a separate saw that had teeth on both sides. It had a rip side and a cross cut on the opposite.

Love that saw, recommend it to anyone who will listen.

A disposable blade ryoba (double sided saw) can be had at almost any tool store, like Woodcraft, Lee Valley if you're Canadian or close to it, or even Home Depot. Amazon also carries good brands, and Woodcraft along with Japan Woodworker (a tool importer bought out by Woodcraft) have online stores.

Gyokucho is my favorite brand. More important than the brand is what you will be cutting; Japanese saws have progressive tpi: smaller and more numerous teeth at the base of the saw, where you start your cut, generally getting large near the end, especially on rip profiles. Even with that, they still have different sizes for different uses. 180mm, 240mm, 300mm are the most common sizes for ryobas. 150mm for thin stock and precise work, 300mm for breaking down rough stock or thick stock joinery like in timber framing, 240 as a general, jack-of-all-trades.

Secondly, as Americans have fallen in love with Japanese blades, Japanese manufacturers took notice and now produce saws with tooth profiles suited for American hardwoods- although even American softwoods are still sometimes harder and more prone to breaking teeth of Japanese softwood saws than Japanese softwoods.

If you do cut American hardwoods often, here is a general purpose ryoba: https://www.amazon.com/Gyokucho-Double-Ryoba-RazorSaw-Hardwoods/dp/B001Y4ZUJW/ref=sr_1_2?keywords=hardwood+ryoba&qid=1564430848&s=gateway&sr=8-2

It's a disposable blade, once you dull it you can replace it. Even so, I usually use a joint powertool-handtool process, and have that exact hardwood saw for three years now and it's still just as sharp.

That's certainly an interesting issue. I'd say get a japanese dovetail saw and maybe one of these. Start a straight and plum cut with the saw that has a spine and then finish with the fine tooth side of the second pull saw. Japanese saws are miles ahead of any western style saws. Highly recommended.

I use this saw: https://smile.amazon.com/Gyokucho-Double-Ryoba-RazorSaw-Hardwoods/dp/B001Y4ZUJW/ref=mp_s_a_1_7?keywords=ryoba&qid=1562605982&s=gateway&sr=8-7

It has shorter teeth for cutting hardwoods. It has worked well so far but I haven't used it for something like Ipe. I think it should work fine other than being a bit harder on the blade.
