Onnit Steel Mace

Name: Onnit Steel Mace
Brand: Onnit
Rating: 4.67 (3 reviews)

The Onnit Steel Mace is a single-piece steel training mace built for rotational strength, shoulder mobility, and full-body conditioning that a kettlebell or club doesn’t replicate as well. It’s offered in five weights (7 to 25 lb) sharing a thick, well-knurled, powder-coated handle that multiple independent reviewers rate as the best grip and finish in its class. It suits lifters who already have some barbell or kettlebell experience, since safe mace flows demand more shoulder mobility and control than most beginners start with. Onnit has since discontinued this mace, so it’s no longer available new from the manufacturer.

What is a Miscellaneou?

What’s in Miscellaneous

This is the catch-all for the conditioning tools and accessories that don’t fit a single equipment class — weighted vests and plate carriers, medicine and slam balls, plyo boxes, ab mats, and the odds and ends that round out a garage gym. Items land here because their job (loaded carries, jumps, core work) cuts across the categories rather than sitting neatly inside one.

Who it’s for

Anyone filling in the gaps around the big pieces. If you already have a rack, bar, and plates, this is where you find the vest for rucking and weighted push-ups, the ball for slams and wall throws, or the box for step-ups and box jumps. Match the tool to the training you actually do — a plate carrier for conditioning and rucking, plyo boxes for explosive work — rather than buying the whole shelf.

The Onnit Steel Mace earns its reputation as one of the best-built maces on the market: two independent YouTube reviewers with years of mace-training experience each call it the best in its weight class, citing a noticeably thicker, better-knurled handle and a smooth, no-slip powder coat that holds up to outdoor abuse without flaking or rusting. Build quality is the clear standout — GymRadar’s 4.67/5 (3 reviews), a 4.5/5 editorial score, and consistent praise across sources all converge on the same point. The weakest dimension is accessibility: this is not a beginner’s tool, reviewers recommend prior barbell or kettlebell experience, and getting full value out of the format means owning more than one weight. Onnit has also discontinued the mace, so it’s no longer purchasable new from the manufacturer.

+Functionality: the offset weight builds rotational strength and shoulder mobility that a kettlebell or club doesn't replicate as well (Onnit)
+Build quality: a noticeably thicker (~2") knurled handle with a smooth, no-slip powder coat that two independent YouTube reviewers called the best in its weight class
+Durability: the coating held up to outdoor and cold-weather use without flaking or rusting, unlike cheaper competitors whose coating "goes away in like one month" (The Flowing Dutchman)
+Versatility: five weights (7-25 lb) share the same handle profile, letting lifters progress from beginner to advanced on one brand
+Value: rated 4.5/5 and called an "affordable investment" relative to its build quality (OlympicWeightSetReview)

−Functionality: not beginner-friendly — reviewers recommend prior kettlebell or barbell experience before picking one up
−Value: getting full training value requires owning multiple weights, since one mace covers only a narrow range of exercises well
−Versatility: the top 25 lb weight may be too light for very advanced athletes, and Onnit's heavier Quad Mace variant isn't worth its premium (MISSION: Capable.)
−Value: Onnit has discontinued this mace, so it's no longer purchasable new from the manufacturer
