Okay, Ko-Ken released their 72 tooth 3/8 ratchet (up from the old 36t design) a few years ago. The 1/4" (as I recall) was supposed to be released a few months after the 3/8", but it never happened. The delays went from months into years. The story was that Ko-Ken engineers couldn’t get the spring pressure on the pawl just right to give the 1/4" that same very low backdrag that Ko-Ken ratchets are known. At any rate, it built up a lot of demand for the 72 tooth 1/4 ratchet that had gone unsatisfied for years.
All of the above said, Amazon’s price is the best price you’ll get on this ratchet, anywhere. Be careful, as it’s easy to confuse the old 36t design with the new 72t design – and note, this one also comes with the push button release, as well. If you check out Ko-Ken USA’s website, you’ll see model #2725ZB is, in fact, the 72 tooth design. Here’s the link to Ko-Ken USA .
Z-SERIES 1/4" 72 TOOTH KO-KEN QUICK RELEASE RATCHET
Ko-ken ratchets are known for their very low backlash, small head sizes, and high torque ranges. We designed the new 72 tooth ratchet without compromising on our traditional strengths. The patented design of the 72T combines the low backlash, small size, and has a 10% higher torque limit in comparison to the 36 tooth ratchet. The legacy 36 tooth ratchets move 10°/click. The new 72 tooth ratchets move 5°/click.
The design changes include moving from the single pawl of the 36 tooth design to the patented dual pawl of the 72 tooth design. The dual pawl 72 tooth design utilizes a single spring. We took four years of testing to perfect the low spring pressure needed to maintain Ko-ken’s hallmark low-torque backlash. The finer 72 teeth design creates more surface area contact with the gear; thus, it has a 10% higher torque upper limit.
