KO-KEN 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.

Good, Fun, Important Topics
Format: Paperback
Good, solid, read for ages 12+. Somewhat unrealistic and yet believable story of two strong young female characters traveling west disguised as boys. Couldn't stop reading it until I was finished with the book, and now my granddaughter is doing the same. This book has many relevant themes about race, gender, class, religion, and other stereotypes and is an excellent choice for a classroom or family read aloud. Get it.

Wonderful story, great for book club though written by a young adult author.
Format: Kindle
Such a “cliffhanger” for me, a just could not put it down. I read this Wild West historical novel three times, that is how good it was. Such great fun for me, while got the ladies in our book club talking about growing up, being brave.

My pick for Best YA from 2015
Format: Kindle
I don't usually like Westerns, but this historical novel reads like a racially diverse Little House on the Prairie. There's a touch of romance, but the most important relationship is the friendship between these two resourceful girls. The writing is superb with well developed characters, a fast pace and a fine sense of place and period (1849). Despite dealing with tough issues like murder, slavery and racism, it still manages to be a feel good story, appropriate for tweens as well as teens. The girl protagonists are 15 and 16 and the boys are a bit older. This debut tops my list of best YA from 2015 that I've read to date: http://blog.sarahlaurence.com/2015/12/best-ya-books-of-2015.html

Nice
Format: Kindle
There is some attempted sexual violence. Otherwise this is a good book for middle and high schoolers. Story of a Chinese American and African American girl on the run in the wild wild west.

... into YA Westerns and I have yet to be disappointed. Under a Painted Sky is a diverse
Format: Hardcover
Over the past year I have made a foray into YA Westerns and I have yet to be disappointed. Under a Painted Sky is a diverse, cultural infused tale of two girls, Our main character, Sam a Chinese, newly orphaned girl, teams up with Annamae (Andy), an African-America, runaway slave. Together they flee St. Joe, Missouri disguised as boys and begin on the Oregon Trail. They soon join three cowboys who help keep them safe and teach them how to survive. I think what I loved most about this book is how Lee was able to incorporate Sam's Chinese heritage and beliefs along with Andy's and intertwine all it beautifully into this richly told story. Sam's and Andy's friendship was also a highlight of the book. It caused for some great moments, some funny, many heartfelt, and I was glad to see such a positive example of female friendship in a YA novel. Although "girl disguised as boy" seem to be a common theme in YA westerns I did not mind it here and thought Sam's inner thoughts about the challenges of pretending to be a boy were hilarious. I think Lee struck the perfect balance between an adventure story, a coming of age tale, and portrait of what life could be like for minorities and females in the 1800s
