Kenny Koehler

Managing Editor

Kenny holds a B.S. in Biology and a minor in chemistry. While that might not sound like a direct line into the power tool industry, his analytical and scientific mindset helps him design repeatable testing methods for Pro Tool Reviews’ head-to-head testing and offers highly objective comparisons in his reviews.

Kenny’s life around power tools started early. His grandfather was an airplane mechanic in WW2 and took up woodworking as a hobby after retiring from the power industry. Building everything from bookshelves to lazy Susans, he became extremely accomplished while his young grandson observed, fascinated at the way raw wood could turn into something both beautiful and functional. In fact, Kenny still uses several pieces that his grandfather made more than 30 years ago. At home, Kenny’s dad made the family budget stretch further by doing many DIY repairs around the house. From his dad, he was able to learn irrigation, landscaping, car maintenance, basic electrical, and more. He even rewired their bass boat for fun one weekend as a young teenager.

At least, those are the numbers manufacturers tout in the marketing. But those numbers are off from what we found in our backpack blower shootout. In some cases, the numbers were way off. […]

Ryobi 2800 PSI Pressure Washer with Honda Engine

With summer upon us, I got my hands on the Ryobi 2800 PSI Pressure Washer featuring a Honda GCV160 engine. The work on my plate was mainly light- to medium-duty, so 2800 PSI was enough power for what I was looking for. While not all Pros really consider Ryobi when looking for a pressure washer, […]
