I'll give this tool a four because I took the risk and bought it, although the seller responded to a potential buyer's question as to whether the handles were aluminum or steel by stating that they are made of aluminum, which they are not. They look like solid stainless steel or composite steel. In my opinion, this is a critical strength issue and quality factor. Warning: I haven't used this tool yet, but my careful analysis shows that the tool should work satisfactorily. Only downside is the plastic body, which is a bit cheap but has nothing to do with the performance of the tool.
