Buster + Punch Door Knob Set - Linear Knurl

A Door Handle You Actually Feel

Most door knobs are an afterthought, whatever came in the builder's merchant box. This pair is solid metal from front to back, with a fine linear knurl cut into the grip so your hand lands on texture rather than smooth, characterless metal every time you open a door.

Choose Your Finish

Linear Knurl gives a finer, more restrained ridge pattern than our Cross Knurl sets, so it tends to suit pared back, minimalist interiors rather than a heavier industrial look. Steel keeps things cool and neutral, Brass adds warmth, and Welders Black lets the knob all but disappear against a dark door.

How It Works

This is an unsprung knob set with an architectural 4mm rose, 57mm across and projecting 40mm from the door face. It's built for a long backset, lightly sprung, two way rotating tubular latch or mortise lock at 82mm, and fits doors from 30mm to 60mm thick as standard. The fixing centres are set for UK latches, and the set includes the through bolts and spindle needed to fit it.

Where It Works Best

This set is built for interior doors only, bedrooms, studies, internal hallways, rather than an entrance door exposed to weather. If you want a bolder, more tactile grip instead of this finer ridge pattern, our Cross Knurl door knob set uses the same fixings and door thickness range, so you can mix the two patterns across a house without any compatibility issues.

Made By Buster + Punch

Door hardware was one of the first things Massimo Buster Minale turned his attention to after founding Buster + Punch in 2013, moving on from the custom motorbikes he'd been building by night while working as an architect. His reasoning was simple: if a door handle gets touched every single day, it deserves to be made properly, in solid metal, rather than treated as an afterthought like most builders' hardware.
