One of our all-time bestsellers — and for good reason. Everyone gets this one.

Featuring a silhouette of a hammer and the unforgettable line “Attention: This is Not a Drill,” this design has become a signature piece across the entire Of Moose & Mountain brand. It’s witty, bold, and instantly recognizable — a guaranteed conversation starter at any craft fair or hardware store checkout line.

Some of the best ideas strike when you’re not even looking for them. The Woodworker Wisdoms series was born one afternoon when I headed down to my basement workshop to grab a screwdriver — and, out of the corner of my eye, noticed my coping saw hanging on the pegboard. The phrase “This is my coping mechanism” instantly came to mind. By the time I got back upstairs, the whole concept for a collection of tool-inspired, tongue-in-cheek t-shirts was taking shape.

Each design in the Woodworker Wisdoms lineup blends subtle humor with clean, vintage drafting-style artwork — the kind that speaks to makers, tinkerers, and anyone who finds peace in the rhythm of a well-worn shop. Whether you swing a hammer or just appreciate a clever pun, this series is for you.

Collect them all — and wear your workshop wisdom with pride.
