I purchased the cr301jf model about 3 years ago. This was my first tijima chalk box and wow was I impressed. I'm a roofer by trade and use a chalk box daily. The positives:Crisp lines, doesn't spill too much excess chalk and practically unbreakable string. We use a heavy bodied permanent red chalk and this works fine without jamming up. In the several thousand uses I have not a single jam or any stripping of the gears. The line hook is top notch and holds tight. The Unit is easy to fill and has a clear housing to monitor remaining chalk level.Now the negatives.The locking line stop mechanism is located in an area where it's easy to accidentally flip it into the locked position while handling the unit. The rotating finger grip on the handle broke within a year. It was still usable but a bit more cumbersome and uncomfortable to retrieve.The small line feeder "needle hook" snapped at the end (it has a small T handle) making hard to remove from it's housing.I used this box for 2 years straight until I purchased another identical model. The handle broke in the same place as the first one after about a years use. I now realize that the rotating finger grip on the handle did not break but simply wore out to the point of failure.I am very pleased to say replacement parts for this model are available at reasonable cost. Even though I've had some problems with this chalk box it easily beats the 10-15 different models I've used in the past hands down. . This includes Irwin , Dewalt, and Stanley and a score of others. I do have to note that DeWalt makes the some of the worst boxes I have ever used. None of these perform or last as long as the Tajima.I am knocking off a star for the handle issues ( luckily I was able to purchase replacement part) but doubt I'll ever purchase another brand again. I'm sure for the average DIYer thus would last a lifetime. 😉

Bought this three years ago it’s only over broke once. The size of the strings thickness is perfect for snapping lines on concrete. It doesn’t over coat chalk either. Your line will be more accurate and work will go very smoother. For the value this is the string to buy for sure 5 stars.

Absolutely love the TAJIMA Chalk Line - it's perfect for precise markings and the jam-free feature is a game-changer. The extra bold 1mm snap line is amazing for visibility, and the five-gear quick retrieval is super handy. Highly recommend this for anyone needing accurate chalk lines!

Best chalk line ever. Clean sharp line. String is tough and even when it gets wet it stays strong for years.

The TAJIMA CR301JF chalk line is fantastic! The 1mm extra-bold snap line creates sharp, visible marks, and the five-gear retrieval system ensures smooth, jam-free operation. It’s durable, easy to use, and refills quickly. Perfect for professionals and DIYers alike. Highly recommend for precision and reliability!
