Why is the angle of the edge of a tool 80 degrees in caulking and fullering?
That makes sense. Can the angle affect the durability of the tool?
Yes, the angle can affect the durability of the tool. A sharper angle means a sharper edge, but it also means that the edge is more fragile and more easily chipped or blunted. So, it's a balance between sharpness and durability.
