Ko-ken Tools 3/8" Sq.Dr. Ratchet Handle 72 teeth Flexible Head Length 280mm Quick Release Z-seriesKO 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 degree click. The new 72 tooth ratchets move 5 degree click.

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 degree/click. The new 72 tooth ratchets move 5 degree/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.

To heavy
Color: Black, Size: X-Large
Vest is heavy and frankly very warm can’t see in what environment I’d wear it because at 40-50 I would use light down coat with sleeves I returned from t same day I reviewed it

gloves without a gauntlet
Color: (001) Black / Black / Reflective, Size: Medium
Needed short gloves with no gauntlet - these are great! Not super thick, but I didn't want heavy gloves for walking. Fit just as expected, I used the measurements suggested on the UA website. So far, good quality and holding up well. I plan on getting another pair!

Worked perfectly for a long, cold run!
Color: (001) Black / Black / Reflective, Size: Medium
These worked perfectly! They aren’t the warmest but do the job for long cold runs in Texas. I ran a half marathon in 40 degree weather with these on and they kept me warm. They are a bit smaller in size, similar to what other reviewers have said. But I’m a small woman with small hands so the size medium I ordered were perfect. They were warm enough that I took them off at about mile 6. So overall, I’d definitely recommend for a light coverage, snug fit, glove.
