OLFA 9911 Compass Circle Cutter Review

Good circular knife. Made well. The set included 5 additional blades, there is a cover to protect the blade (it also stores additional blades). Quite convenient to use. Bought and forgot =)

I used this to cut a 4-1/4" diameter (2-1/8" radius) gasket from 1/16" thick rubber. It worked much better than i expected which is what prompted me to write this review.i used tacks on the four corners of the rubber sheet to keep it stable while cutting.i made a hole in the middle and through the wood , which I worked on with one of the push pins so I could secure the pointed end of the compass as best I could.

I bought this cutter hoping it would cut small circles; However, the plastic side guard that prevents the tip from piercing the paper raises the blade to a height that does not allow cutting a proper circle as it is no longer. Neither the blade nor the tip can be adjusted in height to eliminate the discrepancy. Also, I thought the size lever would show measurement increments, but it also lacks measurements, so you'll have to guess the size until you get it right.

Needed to cut circles from foam sheets of different thicknesses. The best option I found. It took me half a sheet of practice to find a method that was smooth and worked for me. I had to get up and place the sheets on an empty cardboard box to rid them of any roughness and clutter. I made a simple circle, then a second pass to cut deeper. I used sharp scissors to cut off any remaining pieces so the edges are smooth. It cost $11 because I wasn't able to trim them down to a reasonable size…

The price is just great. Can cut circles from 1/2" to 6" in diameter. Anything thicker than paper should be cut deeper and deeper in multiple passes. Take your time. I was able to use this tool to cut 3/32" thick cork rubber gaskets. Picture attached. Just use a gentle, skilled hand and patience and you should be pleased with the results. As with many tools, much depends on the skill of the user If you are unsure at first, try practicing with a few pieces of material until you are comfortable.

Surprisingly easy to use! I need to cut some 3 inch circles out of acetate sheet for a project. Didn't want to spend a lot of money. Very pleasantly surprised at how easy this little device is to use and it does great fast laps! I don't want a pinhole in the middle. It won't work for you. But for my purposes it worked perfectly. Insert a pin in the center where you want the circle to go. Hold the black part of the pen. Turn. The blade cuts the circle very easily. And it comes with extras so it…

Whatever you say I've had to cut out perfect circles on paper, photos and nylon paper and it all worked great. Works like a compass, just remember not to press too hard on the blade when cutting. Use it on a wooden surface, hold the material with your left hand while slowly rotating the compass with your right. Don't try to get your way the first time. Start gently to get a grove, then go around a few times, pressing a little harder each time. I had no issues with blade drift on my 2nd, 3rd, or
