Buster + Punch Door Knob Set - Cross Knurl

A Knob That Means Business

This set trades in the deep, diamond cut cross knurl for grip you can feel from across the room, solid metal machined bar underneath and hand refined for a finish that holds up to daily use rather than looking good for a week.

Choose Your Finish

Black gives the boldest, most graphic look and suits a properly industrial room, Brass warms things up, and Steel keeps it cool and neutral. Cross Knurl's deeper cut makes more of a statement than our Linear Knurl option, so lean into it if your interior can take a heavier, more textured hardware.

How It Works

Each knob has a 57mm rose and an 8mm spindle, machined from solid metal with an EPL coating. It's built to operate an 82mm backset latch or mortise lock, front fixes to the door with M4 screws, and fits doors up to around 55mm thick.

Where It Works Best

Built for interior doors, bedrooms, studies, internal hallways, rather than an entrance exposed to weather. If you'd rather a finer, more restrained texture than this deep cross cut, our Linear Knurl knob set uses the same rose size, fixing, and latch compatibility.

Made By Buster + Punch

Massimo Buster Minale founded Buster + Punch in 2013, moving on from years spent as an architect at practices including Foster and Partners and Richard Rogers, and from customising motorbikes by night in a Shoreditch garage. Door hardware was one of the first categories he expanded into, on the basis that something touched every day deserves proper materials rather than an afterthought.
