Mikko Salo Inspired

The Rogue War Hammer is an indestructible training weapon designed with a seven gauge loadable steel head.

The Hammer's weight reaches 28 lbs. when fully loaded with lead shot. It can survive training, no matter the conditions. And the pipe length offers more leverage than a traditional sledgehammer so that you can exert maximal force, no matter the target. The rallying cry, "SISU" (the Finnish word for stubborn determination) is laser-etched on the hammer head to remind you to continue on. Make every strike count.


  • Total Length 43" - Handle Length 38"
  • Empty weight 14LB, weight with sand 20LB, weight with lead shot 28LB
  • 38" long handle that passes through the head for the strongest design possible
  • Removable back plate to add/remove weight

Rated 5 out of 5 by from Amazing Product When I opened up the box a flash of light blinded me. The Valkyrie were standing before me with the War Hammer. I reached out and took the hammer and was instantly taken to Odin side. Greeted by Thor we fly from Valhalla and start to battle in Ragnarok. After 100 millennia the Valkyries return me home gloriously from battle. My wife tells me to clean the dishes. With one swift swing of my War Hammer the dishes are vaporized and that's when the Eagles, fireworks, lighting, and fighter jets fly over. 'Murica.... But seriously a great product that is solidly built and a great addition to anyone's equipment.

Rated 4 out of 5 by from Legit, Heavy when locked and Loaded I loaded it with lead bb's since it would be my heaviest option. I really do like this hammer, only downfall is that it is squared, so if you lose focus and you hit the corner then you rebound so hard you better be strong enough to handle it. It would be funny when my buddies would see it I would hand it to them and they would almost drop it because they didn't expect to be so heavy. Back when I baught this the slater hammer wasn't around. I would go with the slater, its safer due to being round. Well build, only worked well with the rubber block. I hit my tire and it wasn't a good comebo it would thud and not feel well. My tire is also 4 ft high laying side ways. I tried a smaller one and didn't like it.

Rated 5 out of 5 by from Filling the head Does anyone know a good filler that won’t come out the plate in the spot where sisu is written( its hollow there)?

Rated 5 out of 5 by from Significant upgrade over plain sledgehammer ! I have worked out with this hammer for two weeks; it is a significant upgrade over a traditional store-bought sledgehammer. I will list why, as well as some specifics about my impressions of the product. First, the hammer is very well built. The finish was a change from wood handles at first -- I got blisters which hasn't happened in a while. However, the finish is so far very durable. Really the same as a Rogue rack actually. My next impression was that the hammer was much longer than I was used to. This extra length changes the workout significantly. More engagement of the core and shoulders to swing and control the extra weight. The head is entirely ungraceful - after 100 reps it takes concentration and control to get the head to land on your target squarely. This is, in my opinion, a perk because it adds to the complexity of the workout. Some, however, may appreciate the other hammer's round profile which guarantees a solid and predictable hit every time. Personally, I like that I get punished when I don't get a solid hit. All in all I am very happy that I bought this instead of another store sledgehammer. It gets a whole star just because of cool-factor.

Rated 4 out of 5 by from My Shoulders Hurt Great I have been working out with this hammer 4 to 6 nights a week since purchasing it over 2 months ago and I have seen great advancement in my pull-ups and cleans. Having been splitting wood by hand for 2 solid decades now (Thank god dad started me young) I have been shocked by what an extra foot of handle and a couple extra pounds can do for a workout. Before buying this hammer I was using a splitting maul to do the same workouts for about a month, but I can tell a huge difference between that and this Sisu Hammer filled with river sand. However, I was greatly concerned upon opening the box by how thin the steel is on the handle on this equipment. At first I was hesitant to try hitting targets with it (I have a bad rep for breaking sledgehammer handles) but after around a thousand blows on an old bald truck tire; this sucker is pretty solid. I am still hesitant to make a lot of contact with it; but buy it-fill up the head-ignore all the "brosatru" and "mjolnir" jokes- find a few good workouts online and stick to them regularly- you will not regret it, and your shoulders will astonish you. Strength, endurance, and flexibility in one workout. And yes; even splitting firewood is quicker now.

Rated 5 out of 5 by from #1 Piece of Equipment in my home gym! I got the SISU war hammer as a gift for christmas and has been in daily use since! I have a variety of steel maces and this one is by far my favorite for the unique design and adjustable weight load. It has handled a variety of workouts and is my go to now for hitting the tractor tire. I also added a little paint job to the "SISU" plates. Highly recommend to anyone who is looking for their next piece of gym equipment.

Rated 5 out of 5 by from Full-body killer My buddy has one filled with lead shot that's right at around 28 lbs. this thing is insane. It's so effective at its fullest load, I'm wondering if the mace-style hammer is even remotely necessary at my level.
