Around 2 months ago I saw a Kickstarter campaign for a new titanium modular bit ratchet, and ever since then I’ve seen dozens of other versions on Amazon of similar tools.
The premise is rather simple. There’s a core ratcheting component, with 1/4″ hex bit sockets on 3 sides, and the included extensions can be used to extend the reach of the bit ratchet core or as handle components.
You can use it as a ratcheting T-handle driver, or as a non-ratcheting inline screwdriver.
It seems like a neat concept.

There are many different brands all selling the same or similar tool sets. The one shown here is from “Kelin.”

As for sample application, the tools are often described as being suited for use on household repairs, furniture, electronics, computers, bicycles, DIY, and random other stuff.
One brand advertises that you can use it on watches, which I doubt.
I like the idea of the design, and hope that more mainstream brands give it a try.
Competition is fierce between all of the different brands. While I see some differentiation, most appear to be the same tools in near-identical packages.
Here are some tool sets by various Amazon marketplace brands:
- Kelin 43-in-1 Set
- Bomivoi 42-in-1 Set
- Prekull 42-in-1 Set
- Saker 42-in-1 Set
- Sakerplus 42-in-1 Set
- MrToNo 42-in-1 Set
- Usuauu 24-in-1 Set
- Vman 24-in-1 Set
- Elead 40-in-1 Set
- MrToNo 74-in-1 Set
- Disen 43-in-1 Set
- Anvanna 42-in-1 Set
- Faireach 42-in-1 Set
- Fideco 74-in-1 Set
- Oria 42-in-1 Set
At this time, it seems like this type of tool is only available in online marketplaces. I wonder how long it’ll be before Home Depot (Husky), Lowe’s (Kobalt), Harbor Freight (Icon?), or Walmart (Hyper Tough) launch similar modular ratchet tool sets of their own.
