Hmm, I was just hand-drying a pint container, and I noticed some lines on the inside. They feel like etches/scratches in the plastic on the inside. It kinda seems like the blade may have run up against the inside of the jar...
Anyone else seen this happen in their jars? I am kind of perplexed. The placement makes me wonder if we used it once with the jars not quite properly in, so that the pint was not perfectly centered on the blade, but that seems really hard to believe!
