I own an older 10" makita with a 1" spindle. The newer versions have the 5/8" spindle. I am unable to find a replacement carbide blade for this saw. Do you know of other sources?

In addition would you give me your comparison in quality, accuracy, design approach with the Japanese power tools vs. the European ones.
Why are the Japanese tables/fences so whimpy, etc?
Do they use the tools differently than a westerner?
