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.

This pro compass is the finest quality tool that I have in my collection, it will last me my life and the lives of any other people that have it after I'm dead, this item was a justifiable use of fuel, because it's well made and made without designed obsolescence, unlike the crap tools from the local hardware store, Jab saws, with plastic handles and little vice that break as soon as you use them, and every poorly thought out battery powered junk tool, this tool is fine crafted and a solid tool for the ages.

Es un buen producto, llegó tal cual el modelo mostrado en las fotos, material resitente y de calidad, quizá sea que el me me enviaron tenía un buen tiempo en stock y el material en algunas partes presenta unas pequeñas manchas negruzcas; es el único detalle, no afecta su funcionamiento. Ideal para tener precisión en la medición y el trazo.

こんなに大きなコンパスがあったのを知りませんでした。大きな円が描けて便利、簡単に六角形、八角形も描けて最高。 鉄板に直接けがきもできます。

Heavy duty product, some edges are a little sharp - just touch up with a file.
