I have used replacement blades that I have put in the home center so far, but the inexpensive ones will quickly get bad in sharpness. Even the good ones with grade were distorted due to insufficient strength of the blade muscle, when bribery occurred, it bent. While using it for many years, I learned that there is a thick blade for the first time in a monotaro site. The grinding power took on its own, but it was a comfortable feeling of use, although I needed strength as much as I could not get nervous enough to answer some impossibilities. Only as much as fat is attached ,,,,,. Will it become expensive again when it comes with fluorine processing?
