Why is this so?
I'm wondering why I've stripped the middle third of this saw's teeth.Is it because the saw is designed for softwoods, or is it something simpler such as poor woodworking technique?
I know, I know I agree with you. I shouldn't be so hard on myself.

It's a very thin blade, possibly when the first tooth went it took the rest with it. At first I thought I'd missed a nail with the metal detector.

When I first tried one of these I was very gentle with it, then after a little while not so gentle. It was at this stage that I lost teeth. They are made for the blade to be disposable but I am very surprised to see so many teeth gone in one cutting session.
Originally I started with the one you had and found for what I was doing a shorter blade(180mm) was better option for me. I found this image on the Japanesesaws website.

This is my go to saw for almost everything and yes I have lost teeth and blunted the rounded part of the saw. I have used this saw to cut Pine and Jarrah. It cuts a little slower in the hardwood but it still gets through it with little or no pressure.

Impressive - I've never seen anything like it. Than again. when I am using any Japanese says, and especially a Dozuki I am putting NO pressure on the blade - I am just barely holding it to the point that it almost slips off my hand. Basically I am using my hand just to guide the saw and I let the say do the cut... Yes - there might be an explanation to what I see - is posible that you used a rip Dozuki for a cross-cut ... and it wasn't working as you expected, and you increased the pressure too much.

I was using it for crosscutting, possibly lost concentration and pushed instead of pulled with some pressure. Mind you it was cutting beautifully before the teeth went and usually when I do make the mistake of pushing on the cut I would normally kink the blade or partially snap it, that's happened to me once with a thicker Japanese blade.

Cristos, certainly looks sturdy, where did you get it?
Cheers.

I ripped off a few teeth on the same saw when I first started, didn't manage to take that many though.
As rmihai said, apply as little pressure as possible when using fine Japanese saws. If you use the full length of the blade, you'll find they cut very quickly with very little effort.
I actually moved to 'Z' instead of Ikeda as they're not quite as delicate (still managed to lose teeth though....)

Well at least I'm not alone, so tell me were you cutting softwood or eucalypt. I'm not sure what type of Oz hardwood I damaged the saw on but it was dry recycled timber.

that's the most probable reason
while many Japanese saws are designed for cutting softwood, you can get ones specified for hardwoods -- but I'm not sure about recycled eucalypt
years ago I destroyed a saw cross cutting Jarrah floor boards. We tend to forget that these saws are generally designed for cutting small section softwoodsregards from Alberta, Canada

Originally purchased this at the Working With Wood Show in Sydney from a company called The Wood Works. I tried yesterday to get into their webpage but having trouble, I think it might be our work proxy server that is restricting me. A quick search resulted in finding this saw at this webpage, https://www.japanesetools.com.au/col...ucho-180mm-saw. I have not had any dealing with them so I am not able to comment.

Those blades are not meant to cut Gidgee or concrete, both about the same hardness

For some reason I equated a fine toothed bandsaw with a fine toothed Japanese saw, hence my reasoning (incorrectly) for grabbing the fine toothed saw for hardwood. This morning the light bulb flashed, the Japanese saw is a pull saw and the bandsaw is a push saw and the teeth's set are different. Not to mention temper and thickness.

Actually, bandsaws are pull saws; the motor is under the table and pulls the blade down through the timber.
I think it was Tassie Blackwood that destroyed my first blade. I've also lost teeth in American Oak
