As with all WASP SST broadheads, the Jak-Hammer features a pre-aligned, Stainless Smart Tip (SST). The edges of the trocar, Smart Tip are factory- aligned with the rise of the three stainless steel blades creating a straight cutting path that opens a gapping wound channel, ensuring maximum penetration. The three surgically sharp stainless steel blades of this mechanical broadhead fold forward in flight and are retained by an O-ring. Blades deploy on impact and fold back to a cutting diameter of 1-3/4  or 1-1/4 inches.

Comes in a 3-pack.

Stainless Smart Tip

Stainless Smart Tip

The edges of the SST tip line up with each blade and paves the way through bone and tissue, creating pathways for the blades to follow, resulting in better penetration. Not held together by tiny screws or pins, but pressed onto the ferrule, it will never come off or out of alignment. It’s one Smart tip!

Reputation Award Wasp

Reputation Award

Broadheads live or die by their performance. Advertising and celebrity endorsements only keep a broadhead on the shelf for so long. Eventually word gets around at the archery shop. Our line of broadheads includes models that have been around for 20-plus years, and are still getting 5-star reviews.

Field Point Accuracy Wasp

Field Point Accuracy

All our heads are designed to fly perfectly when shot from a well-tuned bow, but some of our heads feature a compact, reduced surface area to be more forgiving. Because let’s face it, things happen, tuning issues arise, and you still need to hit where you are aiming.

O-Ring System Wasp

O-Ring System

Our O-Ring System requires the least energy for deployment while offering the most reliability. Once the O-Ring deploys, the blades are allowed to release simultaneously, unlike independent blade locking systems, which require each blade to deploy independently. Made of super tough neoprene, the O-Ring material will never weather, crack or break down, even in freezing temperatures.

I’ve had the opportunity to take several deer and a turkey with this head, and it continues to impress me. I’ve never had a deer go more than 75 yards, and the holes are nothing short of amazing. Confidence in your broadhead is everything. I’ve shot through ribs, shoulder blades, and even a buck’s femur (completely my fault, not the head) all resulting in short blood trails and recovered animals. These heads fly true, are tough as nails, and surgically sharp. I absolutely love these broadheads.

I used the Jak-Hammer two seasons ago with nothing but great results. Didn’t have to do much tracking, as I watched the first four deer pile up. The only true tracking job (60 yards) provided a great blood trail. Last season, I got caught up in the rave of the RAGE 2” display of flesh yeilding devastation; however, I did more tracking last season and the beginning of this season while shooting the Rage Extreme. It got to the point of being frustrating. On January 1st of this season (not a New Year’s resolution), I decided to go back to the Jak-Hammer and I am glad that I did. I was pinned down with a nice 10 underneath me and 2 shooter 8’s both within 12 yards. Long story short, I had to take a not so popular shot and arrowed the buck between the shoulder blades. I felt completely confident that the Jak-Hammer would get the job done, and it did. Although I had to track the deer, which I figured would be the case at that angle and shot location, I found him at 100 yards. A few days later, I nailed a 110 lb. doe at 40 yards and watched her fall at 75. The Jak-Hammer’s 1 1/4 inch cut is nothing short of amazing, and I will be shooting them from now on!

The Jak-Hammer as impressed me beyond belief. I did some testing with them today and not only do the fly just as accurate as my field points all the way out to 80 yards, but they are the most durable mechanical I’ve ever shot. I took the same broadhead with the same o-ring and shot it into a target 30 plus times, through a 4’ thick chunk of ice, through a steel belted tire, and after all that I just need to replace the blades and its good to hunt again. The ferule and tip are in great shape! Also the 1 3/4” looks devastating and it opened every single time no matter what i shot it into. This broadhead will for sure be the star of my quiver this year!

by Austin Carpenter

Tried and True mechanical. Sharp as a razor blade and shoots perfect. Have these along with the 2 blade Jak Knife. Seriously killer broadheads! I’m a Wasp fan for life

by Hank

I have used the Jak- Hammer since they came out in the 90’s. I almost gave up bow hunting before a friend told me about them. I have not lost a blood trail since using them. There is nothing that has come out that has even made me think of not using them. Please keep making them.

awesome love the 3 blade

by david a hurlbert

nothing but good things to say about wasp jackhammers.all deer hit with them went down in under 30 seconds.

by Spencer Sousa

This is an outstanding broadhead.I can’t say enough about how sharp and tough they truly are. I had a pass through on a doe that was at 22 yards and she ran no more than 20 yards from where I shot her. After recovering my arrow and inspecting the broadhead, I found that everything was still in great shape. Even the blade retention band had not broken but had just slid all the way back to my fletching. After cleaning the doe I found out that the broadhead had broken a rib on either side of the animal and not a single blade broke(this is what really amazed me.). All in all, i am very happy with this broadhead and will continue to keep using them.

by Dan Schuller

I have used this head for a number of years.  I am impressed with the durability and field point accuracy beyond 50 yards.  The Jak Hammer leaves a great blood trail and I am yet to track a deer beyond 50 yards! I would highly recommend the Jak Hammer, you will not be disappointed with the reliable performance!

by Adam

I just took my 36th deer with these heads tonight and once again they performed flawlessly. I am ultra particular about my archery setups and equipment, if there’s even the slightest doubt in my mind about a product I will not use it.  In the end the broad head is the key to your success in archery, and I will never trust any other broad head than the Jak Hammer. They’ve assured me many clean humane kills and I’ll continue to use them as long as I’m archery hunting.

by Dan Daddio

At 30 yards the 120 class whitetail would not stop! My shot went a bit further back than I wanted but the big 1 3/4 blades caught the liver ensuring a kill! Haven’t lost a deer with these heads yet! You can’t get what you don’t cut! These heads do the damage!

by Dan Glenn

I have been using the Wasp 1 3/4” Jack hammers since 2005. I have been bow hunting since the mid eighties and have tried all kinds of broadheads, both mechanical and fixed blade, and have yet to find a broadhead as consistently effective and accurate as the Wasp Jack hammer. I shot a buck last Saturday and the Jackhammer performed like it has so many times before. I have complete confidence in them. If you haven’t yet tried them, give them a chance, I would be surprised if you are not impressed with them.

Hands down a super sharp, field point accurate, massive cutting diameter, tough broadhead.  Have used these for years, I usually harvest 2 - 3 deer a year.  Have always had excellent blood trails, pass through’s and often deer have expired with in sight of my stand.  Many under 30 yards.  With no screws or mechanical locks to fail, select a-cut-option, I believe this head is as GOOD as it gets!

by John Garner

I’m a bowhunting fanatic and I’m constantly searching for the holy grail of broadheads. And I’ve tried them all. But these are the best I’ve shot.  Durable, tough and they create devastating wounds on deer. What impresses me most is that they fly perfectly with my set-up. Absolutely field point accurate. I highly recommend

by Lee Phillips

I have been using this head for decades.  These simply can’t beat in all areas—quality, accuracy, sharpness, and durability.  I’ve taken several whitetails bucks that were 200 pounds or better, and this head shoots right through them.  The entrance and exit holes are simply huge!!!  I spend days and days sitting on the stand and I wouldn’t use anything else.  I can set there and hunt with full confidence— I know if I get the buck I want into shooting range—he is mine!

by John s. In WI

Between me and a friend doing professional deer culling for various cities and personal harvest of whitetails, we have figured that we have killed 250 plus whitetails with these broadheads. Never one broadhead failure, period. Good advertising doesn’t make a good broadheads. You want the best, shoot wasp. Wish the sold them by the case!

by Zack

No other broad head holds a candle to the wasp jak-hammer. I have never had one failure with this head and the entry on impact is absolutely amazing. Not to mention the blood trails are insane. Looks like someone walked through the woods with a red paint bucket. Once you shoot a wasp you will never want to go to another broad head.

by Tim

Took my first deer with a bow in 34 years with a jak-hammer today. The shot was back and angled out the left hind quarter (my fault). Deer only went 30 yards. Massive blood loss. Will never switch broadheads.Thanks for the great product!

by John in WI.

by Jake hudson
