I am a finish carpenter. I use this for everything, beams, columns, casing, baseboard, anything that needs scribing. I only pull out my compass when it’s over 1/2 inch, or scribing into something like rock or other odd shaped items. However thats not often. Also way easier to see on wood especially walnut. I have tried multiple scribing tools and I have liked this the best. Small, light, it works great and takes up little room in my tool belt. I hope they make one that goes up to a inch someday.
