My doorknobs bore the crap out of me, and if I wasn't living in a rental, I'd replace them. The sheer amount of times I touch them every day going in and out would warrant it.
I've got my fantasy replacement knobs all picked out; I'm digging Modknobs' selection of modernist doorknobs, made from either hardwoods like walnut and oak or, get this, actual hockey pucks.
Their product line-up comes further divided into two subcategories: A standard-operating-procedure center-mounted option, and the off-center "Pivot" models, which rotate eccentrically.
They're made in the USA...and come with an attendantly higher price tag, ranging from $95 to $125 a set. "We've chosen to use spendy but superb Baldwin hardware (solid brass, 3 lbs./set)," says the company, explaining the higher price tag. "Several of our designs require waterjet and laser cutting. And all of our design, engineering and custom construction is done here in the U.S. We can't compete with doorknobs mass-produced in Asia. But we can offer a nice alternative for those seeking innovative, contemporary, really well built doorknobs."
