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.
Use included circle stencils to draw circles less than 1" diameter (1/16" to 9/16" diameter).

Comments about Helix Circle Ruler:
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
Bottom Line Yes, I would recommend this to a friend

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.!

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.
Bottom Line No, I would not recommend this to a friend
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!
