I came up with the idea for kelvin in May 2006 while hanging a picture with my wife in our tight condo. I had to haul the toolbox from our bathroom closet (because that’s where you keep a toolbox when you live in a condo…if you even have a toolbox at all). I needed a hammer, measuring tape and level just to hang this picture. It dawned on me that I could build a house with these tools. I only needed to tap a small nail into the drywall…clearly this was overkill. And that’s when the idea hit…why not invent a modern urban tool for modern urban living. One tool that could tackle hundreds of everyday jobs, like hanging this picture, with ease. It had to be super functional, compact, rugged, ergonomically correct and styled for urban living…not a construction site. kelvin.23 is the result.
