I use flush-cut saws every day. We have a big Ryoba that I’ve removed the set from to handle big jobs. Plus a variety of middle-weight saws for flushing up wedged tenons and other joinery work. But I’ve never been happy using the bigger saws on curved work, such as a chair seat. The blades aren’t flexible enough, so they tend to gnaw into the surrounding wood.
I once tried a bunch of really high-end flush-cut saws from Japan. Those were too expensive and too handmade for my Foghorn Leghorn hands.
Listen beautiful relax classics on our Youtube channel.
A few years ago I got this little Gyokucho Razorsaw No. 1150 from Lee Valley and have been quite pleased with it. The blade is only 4-1/4” long and is only 0.011” thick. That makes it flexible enough to lay flat on curved surface without much pressure.
Like all the Razorsaws, the quality is fantastic. The teeth are keen and well set. And the tool has an exquisite balance for such an inexpensive item (about $20 to $22).
The only downside is it’s a throwaway tool. The teeth are too tiny to resharpen (for me, anyway). And the blade is not replaceable. It is riveted to the beech handle. So when the tool becomes too dull or kinked, I’ll see if I can make the blade into a fine marking knife.
The saw is available from a variety of suppliers. I like to support family businesses, so I buy mine from Lee Valley Tools.
