So far it seems good. VFM

UPDATE: After 300 holes in the ground without finding any iron even once, it broke and now it is 82 centimeters and does not go beyond 40 pounds, it is very difficult. Every time it needs sharpening with a wheel, but the metal is very soft and the tip breaks immediately and becomes rounded and does not cut. It is not useless, but it is nothing like before. Therefore, if you make a hole and find iron, it will definitely break. If you make a diagonal hole in bricks, it may also break. Its material is of lower quality and I noticed that it did not rust at all for so long. The ones that rust are stronger.
