The best tool for a craftsman! I have spent a lot on such tools! Now I won't change it for anything!!!!!

Very good and sturdy construction quality, the body is probably cast aluminum. It has some imperfections in the paint but they are hardly noticeable, overall it is well-designed and has a good finish. The locking mechanism is on the button (button-lock) and its components appear to be metallic, so it is likely to be quite safe to use. The pivot of the blade has brass washers for rotation instead of bearings, which is logical.
Very good handle although I would prefer a more curved body, as shown on the European Milwaukee website.
All the locks and movements are secured with magnets, even the placement of the spare blades in their case, and every movement is accompanied by a satisfying "click". It gives you a sense of stability and safety during use.
The only drawback I find is that the clip for hanging is in an awkward position when you press the button to unlock the blade. Also, its use does not help left-handed people.
Overall, I would easily recommend it to anyone who needs it for tough, professional use where the convenience of changing the blade in 3 seconds and thus having a new sharp tool is invaluable.
For light hobby use, I would suggest looking for alternative options among the wide variety of quality and beautiful pocket knives.

There is none! Very good quality and addictive to open and close. I have it for a year and not a single screw has loosened, it is perfect.
