I have and use the Nutcracker for quite some time for my walnuts from the garden. He is very good in the hand and cracking the nuts as you want it. I can not detect any manufacturing defects or the like. The word "High quality" I do not want to use at this point. He is not "cheap", but he is also "only" a good Nutcracker does what he should. Even a little more violence in the nuts he coped super.
I am very pleased with him and had no fear that he is going or similar broken. Feels like he should keep long, otherwise I'll get back here;)
