The entire body of the file is heat treated and quenched, which has high durability. The shape and depth of the file teeth are uniform, and the cutting efficiency is highThe head is used to adjust the position of uneven serrationsHandle plug-in design, close and durable connectionTPR two-tone handle ergonomic design, better grip, easy to use < p>1. When saving the files, it is strictly forbidden to stack them. They should be kept isolated to avoid self-damage from mutual friction between files. 2.
