Overall It's heavy and feels great (I'm a machinist). It was so good I sent the link to two of my colleagues and they received the same one so we had to engrave our names on it, it's now the official shop deburring tool.
Pros
EASY INSTALLATION. You can change the blade by pressing the locking design, which is very easy. Assembly tips: Place the knife at the very bottom and pull it out slightly so that the holding structure holds the knife in place.
