I've been using a Gyukochu ryoba saw for a few years, and my blades typically last for several months. Recently, I bought a replacement 651 blade from Amazon, and after using it once to rip a black walnut board about 2 feet long, the rip side started to 'skip' over the wood. It cuts way slower than before and much slower than my other saws. Interestingly, the crosscut side is still functioning well. Did I just get a defective blade?

It sounds like you might have had bad luck with your new blade. It's possible there could have been some impurities in the walnut you cut that dulled the blade too quickly. You should check the teeth to see if they’re chipped or deformed; if they look a bit shattered or rounded, that could be the issue. I've had a similar experience, so I sympathize! But don’t worry, Gyukochu blades are usually solid.

Yeah, I had a similar problem once and it turned out to be a tiny pebble in the wood. It totally ruined the edge. Just a little stone can make a big difference!
