This is what Ive been hunting for forever. It actually can cut a smaller diameter than all others ive found and it comes with spare blades! And even has the parts number from a reliable brand to buy even more replacements in the future. While it is a plastic build, theres next to zero flex or bendability unless i use an unreasonable level and angle of force that would not be standard in its use. The adjustability screws tight and holds throughout use without needing to be readjusted.

I have a stack of 50 I cut out of 6-7oz. leather which is fairly thick for a craft project. I needed a round cutter without purchasing a premade die. This works great although I was very skeptical the first time I tried it.I would recommend doing multiple passes without digging in too hard to try and cut it once. Also, in this application it's almost better to not have a super sharp lade due to it digging in too deep and bogging down the process. I was able to cut this state of 50 in about 1 hours.I use a piece of plexiglass below but a cutting mat would be better. This leather is not a uniform thickness so I do about 4 passes and then movr on to the next one. When the sheet is complete, I go back with a pair of scissors and cut out remaining edges. Doesn't take much time and allows me to not cut my plexiglass trying to get ever edge.Lastly, this is my second Olfa Knife. I have a rotary cutter that is my favorite. Quality products indeed.

I bought 2 reasonably priced circle cutters to use mainly on cardstock. The “JEF” HD-01, and the closely priced OLFA circle cutter.I am reviewing both together.The “JEF” is obviously larger and can do larger holes/circles. This model is easier to use than the OLFA and should be able to cut any circle you would need. My only issue is that it uses a Cricut like blade, and includes 2 extra. The blade works great, it’s replacing it if needed that concerns me. You may just have to buy another whole cutter (although at under$10 not a real problem).The OLFA can cut up to a 6” circle, which covers most card crafting. The OLFA is much more compact and made in Japan instead of China. The OLFA has 6 extra blades and can probably be bought from OLFA.Summary: I really wanted to like the OLFA, but the “JEF” is just so much easier to use. The OLFA has a learning curve and could be difficult for many. I think if you just want to cut circles, get the “JEF”.

I needed something to put holes a little less than 1/2" in diameter in the middle of large sheets of heavy paper (less than 1/4" radius.) I had been doing it with pencil marks and an Xacto knife and it was a real pain, and very time consuming, and the results were never perfect. This little tool does a far better job, and is super fast and easy to use.I saw a comment where someone said they could do a 1/8" hole, but I don't see how this is possible. The smallest hole it can make, from what I can tell, is about 7/16" in diameter, or a little less than 1/4" radius. Lucky for me, that's just what I needed.The tool comes with a blade installed, plus five spare blades stored in the safety cover (a separate plastic guard not shown in the photo.)Probably *not* going to work very well on something thick like corrugated cardboard, but would certainly work on heavy flat (non-corrugated) cardstock -- you might just need to run the blade around a few times, no big deal.Oh, and they even give you a little circular thing (about the size of a thumbtack head, with a non-skid bottom) that you can put in the center of your circle, and put the tool center on top of, so that you don't put a pinhole in your paper if you are going to keep (rather than discard) the round piece of paper after it's been cut out. This thing also fits neatly in the blade guard.For best results, I recommend using this with a cutting mat such as the DAHLE Vantage cutting mat (also a great product.)If you need to make perfect, small, round holes in paper or cardstock, I can't imagine a better tool, and a screaming bargain.

I do a lot of miniature crafts and cutting circles has always been the worst part, this thing is awesome. Cuts perfect circles easily, and the size range is perfect for projects big and small

Oh my goodness, this little device has been a godsend. I couldn’t use it on 1/16” thick sheets of basswood, but no matter, I was able to substitute and use chipboard, no problem. It also works excellent on heavier cardstock.

So, I found it easier to use by holding the compass/cutter still and then rotating my paper. However, the center pointer pokes through the soft cushion stopper leaving a hole in the middle of my circle (honestly barely noticeable). Also, on my projects, it was VERY difficult to locate the center of the printer circles. This was difficult to align. The blade is super sharp (i cut myself twice😂 my fault) which is amazing for cutting paper, just be careful.

Got this to make a punch board for my kids upcoming birthday party. Idea of cutting circles in cardboard was daunting. Didn't see many reviews about cardboard so for anyone else out there it does cut corrugated cardboard. I made 15 circles 2.75" diam with minimal strain and the blade is still has life. Easy to use, cuts paper like butter. Cardboard was tougher but not bad. This is a large pizza box I used same thickness as you typical shipping box. Like the blade cover, pad for when circles are your final product and extra blades and blade compartment. Only reason for 4 stars is would be nice if there were clear actual ruler like markings on the lever part with numerical measures.

Watched a few videos on how to use it and then didn’t have an issue. Cut through 20g carton with a few passes and didn’t leave any rough spots. Would recommend.

The best circle cutter I've used. Minimum size is 1cm diameter, the cuts are precise and there are extra blades included in the package. Best used with a cutting mat to prolong the life of the blades.
