I love the el cheapo non locking imitation of this I made with a Matco 88 head and an 18” advance auto breaker bar. Not my most used but when you need it, you need it.Matco 3/8 xl locking flex (18")
Only way to improve that is to slap a DT90 kit into it!I love SK roundheads. The same way I love my New Britain made Napa and Husky wrenches. I'm fully aware that there are nicer tools out there but they feel good in my hand and they get the job done.
I lost track long ago of how many ratchets I have. It's almost criminal to own this many nice ratchets when you don't make a living with them.
You can't hide quality!Interesting to see how many times SK.... and the 45170, specifically..... popped up here.

The production of domestic SK round-heads died when Ideal sold to chinese GreatStar.As a European who never encounters some of the ratchets mentioned here, I’d love to get my hands on a frumpy-looking classic old American ratchet to see what the appeal is.
Since Amazon US claims to deal with import duties and the rest up front, I might order one from there. Which long-handle 3/8″-drive model should I try? Only interested in US-made ratchets, not American brands importing stuff. Considering the Proto J5250, SK 45179, and Williams B-53A. Any of these clearly better than the others for back-drag?
If you sort Amazon reviews of the SK 45170 (a standard-handle model) by “Most recent”, you get a bunch of 1-star reviews and claims it’s not even a genuine SK ratchet. Which is a worrying prospect when ordering from abroad (difficult to return).
My dad swore by round head S-K ratchets. I sure thought they were as good as it gets….until I realized I really don’t like them.
They are an awful lot better than raised panel Craftsman junk, but I sure can’t find a single reason to hang onto them with so many better options out there.

The old Facom 151 ratchets are generally better tools than the old US ratchets.As a European who never encounters some of the ratchets mentioned here, I’d love to get my hands on a frumpy-looking classic old American ratchet to see what the appeal is.

This is also my most used 3/8 ratchet.
Proto ratchets may be ok for industrial/construction use but for automotive they have a large head that's always in the way and are very clunky feeling.As a European who never encounters some of the ratchets mentioned here, I’d love to get my hands on a frumpy-looking classic old American ratchet to see what the appeal is.

Yes you are correct I had forgotten they came out with the Precision 90 line.Proto Precision 90 (or the Mac variants) are pretty hard to beat. They aren't really "classic looking" but they're kickass ratchets. They shouldn't be hard to source but they're pricy.

Grab one from ebay. I have two. One in my box at home and another one in my service truck. Just punch in SK 3870 in the search bar.I wish I would have bought 1 of these before they were discontinued

As another European with an itch for rare and high quality ratchets in our area, I collected a used standard Snap On dual 80 in 1/2" for 60€ (scouting ebay for a while), a Proto J5249XL and a 60's made in USA Husky (New Britain rebrand). All are really nice ratchets. I'd skip the round heads, a pear head design is easier to flick over.As a European who never encounters some of the ratchets mentioned here, I’d love to get my hands on a frumpy-looking classic old American ratchet to see what the appeal is.

The pearheads are. The modern roundheads are a 72t heart-spring style and the much praised vintage ones were 82t (dual pawl 41t).Proto ratchets may be ok for industrial/construction use but for automotive they have a large head that's always in the way and are very clunky feeling.
Williams are decent but older 36 tooth design, Mac has a decent ratchet as does Matco but I'm not sure where either are made, the Matco head is thinner then Snap On action feels good I have one I use at home.
Those premiums have an odd balance with their heavy handle, especially noticeable to me in 3/8 but are a solid unit. My favorite Proto design was the Big Dawg series.Proto is probably best functionality for the money. I thought about ordering the "classic" design but then decided to opt for the modern XL series - just more compact and finer teeth, I really like the form factor.

I can see the appeal of the knurled grip, and the "clacketyness" of the old SKs - it's funny because I've already heard SK fan bois proclaim that the 1/4" and the 1/2" are the better SK ratchets due to their higher teeth countMy dad swore by round head S-K ratchets. I sure thought they were as good as it gets….until I realized I really don’t like them.
They are an awful lot better than raised panel Craftsman junk, but I sure can’t find a single reason to hang onto them with so many better options out there.
I have my late grandfather's 1/2" SK ratchet...it's one of the few tools of his that I have. Yes, I use it occasionally for sentimental reasons.I kept seeing everyone talk so much about the 45170 I asked my uncle and he let me use his but idk I didn’t like it compared to the Snap On 80s I use.
He said maybe you can get a rebuild for higher tooth count but he wasn’t sure. I think maybe it’s too big compared to snap on.
So you guys who use it actually like it better or is it just cheaper than a snap on or nostalgia and makes you feel good to use it even if it’s not the best tool just like emotions?
