This 2-in-1 ruler and compass lets you draw circles from 1" to 12".
Place the center disk hole on your starting point and choose your desired circle size (in 1/8" increments). Insert the pen into the hole and then hold down the center disk. Sweep around with the pen in the hole until the circle is complete.
It has an easy pickup handle.

ruler and a compass
By nancy the art teacher

Comments about Helix Circle Ruler:
I just bought these because all my compasses that are metal are missing parts or are broken. These are easy to use and there are not parts so they should last longer (hopefully). Its also nice having the ruler and the circles they can use in various sizes without using the compass. I use these for an OP-art unit.
Bottom Line Yes, I would recommend this to a friend

ok for personal, not for middle school
By Middle School Art
On the one hand this seems like a really useful tool. On the other hand, it spins in the middle and makes a great helicopter, so greatly increases the strain of a classroom full of middle schoolers with rulers. So far they have broken one a week. These are VERY flimsy, the clear parts are not secured, just lightly pressed in, including the pivot, so they pop out easily. That makes the cool circle template part easy to steal. The thin blue plastic edge however, is what has broken both times. I have decided, after this purchase, to never buy 12" rulers again, from here on out they have to bring their own.
Bottom Line No, I would not recommend this to a friend
Helix Compass Ruler
from Phoenix Az
Works great for creating circles without making holes in your drawing paper like with a traditional metal compass. The plastic rotating center is a bit fragile and does not last the full year in my high school art classes.
Plan on buying again

It is great for making any size circle up to 12 inches in diameter easier to use than a compass such as ties for my 1931 model A with a rumble seat or the tires for my son's semi and trailer all made of wood with no screws or nails just glue It's a great compass and straight edge with a added ruler in inches on one side and centimeters on the other The only problem is the blue edge all the way around the ruler it obscures the lines and things you are trying to measure
In a Category by Itself!
By Mrs. Weinstein, art teacher
from New Jersey
This compass ruler combination is not just the best in its category, it is in a category by itself! I have tried to find another similar product, and it just doesn't exist. It is the easiest, safest, and best compass I have ever given to my students, and they used to fight over the few I had (prior to this order). Once of my paraprofessionals, who is a ZenTangle artist, was so excited to see this product, she offered to buy one off of me! I was thrilled to find this product at Blick, because it is a difficult item to source, at a reasonable price. I was so happy to order these rulers from Blick!
Kids are always amazed!
from Lewiston, MN
I use these rulers mostly for creating circles on paper - The students are always amazed for some reason!Care must be used at the center of the ruler, as the tiny edges that contain the spinning plastic circle are very fragile and could break if not used in the manner it was created for - make sure students don't "play" with the ruler - no snapping, slapping etc.!

This compass is extremely versatile and easy for my students to use. A must in my classroom.

Not for the classroom!!!
By Art teacher
from Tucson, AZ
This ruler would be great for home use...but let me save another teacher from wasting their money! I ordered over 40 of this for my high school art classes. That lasted no more then two weeks! All of the clear plastic pieces are removable. all of the plastic is very flimsy and easily breakable.
A Unique Tool for Your Artist Toolbox
from Houston, TX
I had never seen this ruler until I placed a large order for other supplies for this semester's art class. The Helix ruler combines small circle templates with the ability to draw large circles or arcs up to 12 inches in diameter. And of course, you can use this as a regular ruler for straight lines, measurements, and perspective drawings. A great value, worth at least twice the price!
