I posted earlier about my modifications to a Japanese pull type saw (see "hand saw technique" thread) and have some follow-up information.
Just a summary for you folks that didn't follow that thread: I modified a Japanese saw blade by putting an American styled handle on the wrong end and making it a push type saw. This has worked well for me for the past several years - it has become my favorite saw. You have to learn how to push the saw without bending the blade and disrupting the alignment of the teeth - but that exercise is well rewarded.
Well, the original blade (and the first replacement) was 250mm long. It was getting time to replace it (getting dull). When I was in Woodcraft, I saw the 300mm replacement blade and thought 50mm more would be a good thing. When I got it home, I noticed that the 300mm blade was a little thicker (.030" vs .020") and a little wider. I used my dremel tool to cut the replacement blade to the same profile as the previous one (where it entered the handle) and opened the slot in the handle a little. I thought the extra dimensions would add some stiffness to the blade (not necessary but would be nice). I failed to notice that the 300mm blade had courser teeth and that is the primary reason for this follow-up post.
The new blade is good, but now that I have seen and used both of them, I would prefer the 250mm blade. The 250mm blade was $8.50 and the 300mm blade was $12.00.
I would like to have a rip saw of this configuration, but didn't see fine tooth Japanese rip blades. I did see some Frame saw blades, but I think they would be more like the American styled tooth shape.
This is an economical experiment and I encourage everyone to give it a try. I like mine and I have four American styled saws that now only collect dust (I'm not counting coping saws or keyhole type saws). If you are looking for a fine cut, go with the 250mm - hell for the price, get both and make your own comparison. We all like to make things and most of us like to save a buck or two when conditions are right. Here is an opportunity to make a superior tool that you can't purchase anywhere. Read my original post for tips on working the metal.
