Ko-ken Tools 3/8" Sq.Dr. Ratchet Handle 72 teeth Length 178mm 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.

Worth it! Solid dermaplaner.
Color: Matte Blue
It feels solid in my hand. The blade doesn't seem to be all too sharp, but it works... so maybe that's for safety purposes? I like it and will stick with it for a while.

Hair removal improvements, ooooh! Ahhhhh!
Color: Matte Gold
We were vexed and a little annoyed by that one chin hair removal after a waxing treatment. Lo and behold! Zomchi invented a razor for treatments in between salon wax strips. Painless and easy to reapply hygenically. 🤗
