Because accuracy is good, it is also possible to create a folder and turn it into a lathe instead of a cutter. Because we do not use such a way too much, the price is also expensive and I will make it to the regon in the future. I have neither mark nor 10 marks. There were three pieces that the film called blue coating or peeling off before use. Peeling is crappy. As a cutting grinding stone, it is a high class, so I want you to make it a bit better.
