Your cart is empty.SK Professional Tools was founded in the early 1900s as the Sherman-Klove Company by Mason H. Sherman and Noah Grover Klove. In the early days, we specialized in contract work, producing tools and parts for other companies. After a brief period producing munitions and mortar shell casings during WWI, we returned to our true love and what still drives us today – manufacturing quality tools for the American tradesman. From the original Round-Headed Ratchet to the new SK X-FRAME Ratcheting Wrench, we’ve been innovating for the American tradesman since day one.

This stubby I ran across several years ago. I never throw out tools. It broke in the 80’s and is working in the 20’s flawlessly, just Flippin sweet.

Upgrading my 45170 with this was less than half the cost of buying a new 800720 (same mechanism in a new body.) I think it's a little pricey, but it is a nice upgrade. This would be especially nice to upgrade a ratchet that has sentimental value to you.I haven't used this ratchet much in the past few years, passing it over in favor of ones with more teeth. I think I'll use it more after the upgrade. Classic style and a great grip, now with a modern mechanism.Mine has a bit of a tick-tock sound to the pawl engagement. What I mean is every other click is a lot louder than the one in between. I'm not sure if that is normal, or will ever make a difference in use, but if it does cause problems, I know SK will make it right.**INSTALLATION HINTS** Just a reminder when pulling out the old mechanism and installing the new one to put the mechanism into neutral first (in between forward and back.) The anvil should rotate freely in both directions.I had a devil of a time getting the old mechanism out. I realized the reason was there was so much gunk in the retaining ring groove that I couldn't compress the retaining ring enough to release the mechanism. All it took was one drop of penetrating oil in the retaining ring groove, then hold a pick in the groove and rotate the mechanism 360 degrees. All the gunk in there slid out and the next try, the mechanism came out no problem. Had I done that first, it literally would have taken less than a minute to swap out the mechanisms. Hope your upgrade goes smoothly!

Took about 2 minutes to put on.Comes with internal, grease pouch, and snap ring, and instructions.The ratchet turns smother and can easily switch to left or right. Its worth the money over the original one.

Fixed my favorite old SK rachet to brand new.Works great and for a fraction of the cost of a brand new one. Worth every penny plus.
