## Questions & Answers

**Q: how can i change the lead**
A: like you would with any other compass of this type.  there is a wheel where the lead it attached.  unscrew the wheel, remove any left over lead and input another piece of lead.

**Q: Can you provide information on what size leads should be bought for replacement leads for this compass?**
A: The leads are 2mm, same standard size as drawing leads

**Q: This compass arrived with the lead broken off inside the holder. I cannot load a new piece or even get the old broken piece out help!!??**
A: Unscrew the lead adjuster all the way until it comes off. There is a flat black piece that holds the lead in place. Remove that and the lead will slip right out. Put it back together and good 2 go. Just be careful to not over tighten bc that will break the lead as well

**Q: Included is there another metal point for a double pointed metal divider?**
A: Not that I am aware of.

## Customer Reviews

### ⭐⭐⭐⭐⭐ Well made compass
*by M***O on July 25, 2025*

Love this brand. Great products that help a lot for pattern making

### ⭐⭐⭐⭐ A good compass with a minor deficiency.
*by O***R on February 24, 2016*

I teach math to children from kinder to 12th grade at LAMC, Los Angeles Math Circle, a free Sunday math school run by UCLA Math. Dept. I also give quite a few private classes based on the curriculum I have developed for the Circle. Geometry is an important part of my classes as the part of Math taught most poorly in the US schools. Compass-and-ruler constructions form the bedrock of geometry, so I teach them a lot. This way, I have an extensive experience with various compasses. Out of the compasses I have tried so far, the one under review is my favorite. It has no plastic parts - these always break down rather sooner than later. It's large and sturdy which is very important for younger children. The only reason I give it four stars are the tiny nut heads at the sides of the horizontal bar. Kids are very quick to turn them off, then off they fall, and they are very hard to find because of the tiny size. I advice parents to fix the problem with Super Glue as soon as they get the compass. Once the problem is fixed, the compass becomes a perfect instrument. I wonder why they don't just weld them in at the factory?
