The review

Tom Karagianis, owner of Tarkus Automotive in Milwaukee, WI, is no stranger to working in tight spots. His shop specializes in machine work and European vehicles. Even though he is a shop owner, he and his brother do all the shop’s work. So, that means he has to get his hands dirty and appreciates a tool that helps him get the job done.

Karagianis’ quite simply was impressed by the brute power the tool had for its size.

“It’s hard to explain this tool, unless you use it. It’s kind of neat,” he said. “Its one of the fastest I have ever used.”

So fast that it intuitively feels too fast for its size. “It is so fast I’m afraid of breaking the head off, I don’t use it to reverse something that is stuck,” Karagianis commented. “It’s a mini 3/8″ air ratchet that is the size of a 1/4″ air ratchet. It’s about 7″ long, 8″ with an air fitting.  Yet, it has a 3/8″ head.”

When asked whether he thought he actually could break bolts with it, he replied that he didn’t doubt it’s ability. Rather, he liked the tool and was not used to something of that size packing that much power, so he did not want to use it as rough as one would use a bigger tool.

“Once you loosen the fastener watch out, it is going out!” Karagianis said.

He also liked that the tool was quiet and how the tool felt in his hand.

The box was not so easy to understand. “It seems to have every language in the world on this thing, besides ‘American,’ ” said Karagianis. When pressed about English being the language of the USA he just laughed and added, “What I can tell is that it’s made in Japan, not China. That’s a big deal.”

When asked to give his final comments on the tool, Karagianis simply said that “it looks and functions like the 1/4″ Matco tool, it has the same handle and everything, but it has a 3/8″ head. I like it just the way it is, there’s nothing I’d change.”
