High quality compass
A professional compass, with real weight. Holds in place even without the lock, we’ll have to see how it lasts. But seems very well made, the edges on the steel are pristine. Points are definitely sharp. Practically a surgical instrument.

Heavy duty
Super heavy duty, heavy, high quality. Its as big as my forearm which would be fine if it wasnt so stiff. I find it difficult to open and a bit scared I will cut myself

solid metal construction, but those edges
First thing I noticed was how heavy and solid the metal construction is, like a machinist's tool should be. Action is a bit stiff but that's ok. One thing I would take issue with is the sharp edges on basically every corner of the metal. This is a hand tool and should be easy on the hands. It needs a good de-burring all around. I put it on a shop buffing wheel for five minutes to smooth all the edges. You could probably use a metal file. Next small complaint is the small diameter of the pencil holder. You can fit a normal #2 wood pencil in there, and that is about it. I don't have any mechanical pencils or pens that will fit. I prefer a roller pen and ended up shaving the plastic down so it would fit. Photo shows after edge buffing. Next is that it seems to be uncoated steel. I will probably put a bit of spray lacquer on it to stop it rusting.
