It does its job, I use it for digging in rocky soils. The shape of the tips shows rough work, and I didn't expect anything perfect, but on the edge of the needle, for example, the grinding to shape the needle is very rough and has irregularities. It is also not sharpened to break rocks and requires work. However, for its price, it is worth it in any case, with an angle grinder or a belt sander, it can be fixed. Other solutions are much more expensive.
