3 Year Review: The Spyderco Atlantic Salt Knife

When It Comes To Safety Knives, Less Is More

The Spyderco Atlantic Salt Knife

The Spyderco Atlantic Salt
For our 2nd ever review we figured we'd pull out our favorite safety knife, the Spyderco Atlantic Salt in Yellow. This thing has been around for some years now, and we've owned one for 3 years already, but we feel like it does not get the attention it deserves because it is definitely is worth taking a look at as a choice for safety knife in your kit.

From the spyderco website:
It's been speculated the sheepfoot shaped blade originated with mariners who found the rounded tip especially beneficial when the knife was accidentally dropped (think working on a ship in pitching seas) as it couldn't stab the foot when hitting the deck. It's also been hypothesized that commanding officers on these ships preferred rambunctious hardworking sailors carry knives without pointed tips, especially while in port blowing off steam after months at sea.
Spyderco's Rescue knives are long favored by seafarers and the design has since been embraced by rescue workers, EMT's and ranchers-anyone cutting around flesh in an emergency. Now available in a rustproof version, the Atlantic Salt is a modified Rescue made with state of the art non-rusting H1 steel. The hollow-ground blade is available in SpyderEdge offering remarkable cutting performance in and around fresh and saltwater. The molded FRN handle includes a shackle key and is available in black or bright yellow and features a reversible black-coated titanium pocket clip for tip-up carry on either the left or right side. We recommend threading a thong or lanyard cord through the lanyard hole for back-up retention around water, where once dropped, a knife is often irretrievable or lost.


  • Serrated-blade
  • One Handed Opening
  • Locking lever preventing accidental closure
  • Shackle key
  • Spyderco H1 Steel
  • Removable Belt Clip
  • Lanyard Hole 
The yellow color makes it very visible, even underwater, and the handle is made of FRN - a reinforced plastic material that is extremely tough - meaning it wont get scratched or chipped easily. We've noticed that whenever the knife has fallen onto the deck of our coachboats it doesn't slip around, thanks to the textured grip and the boat's nonskid. 


  • Overall Length: 8.25"/210 mm
  • Closed Length: 4.625"/117 mm
  • Blade Length: 3.687"/94 mm
  • Weight: 2.75 oz/77g
  • Handle: FRN

Spyderco H1 Steel: The Most Rust-Proof Steel We've Ever Seen

Developed in Japan
This H1 Steel from Spyderco is the most rust resistant, rust proof steel we've ever seen. Seriously. We've owned and tested many knives and the picture you're seeing above is taken right after the knife was sitting, closed, in a bag for 2 months since the COVID-19 pandemic broke out. That's all the rust we found! All we have done is rinse the knife off in fresh water after getting it wet, and that's our maintenance. It's seriously awesome!

We Put It To The Test

But - how sharp is it? Well, we put it to the test - we gathered the typical ropes that you'd find in the opti world

  • dyneema
  • vectran
  • polyester
  • cored line
  • uncored line
  • 1.5 to 7 mm line
And here's the results: any line larger than 4 mm it took a couple of passes to cut through but none required much exertion. This knife is sharp! Anything smaller than 4 mm this knife passes through like it wasn't even there.

Final Thoughts

So we've owned the Spyderco Atlantic Salt for a few years now and love how rust-proof it is, the handle size and ease of use.A big downside to the knife is the inherent drawback of serrated knives, which is that they are harder to sharpen. However, they retain their edge longer as the edge does not sit and chip itself on objects, and can rip through rope just like a straight edge knife. 

The blade is purpose built, and will take some getting used to if you are a fan of drop points. It’s a hollow ground sheep-foots knife with a fully serrated edge after all. Remember, you are working around kids and if you drive a RHIB especially, you don't want to accidentally stab anything!
Consider the Salt Atlantic as your dedicated safety knife for those reasons, and if you're interested in picking one up you can find them below

The Post-Opti Life: 29er Sailing And Skiff Culture

 A New Series To Connect Sailors To What's Out There We tried something different with this one as we constantly get questions about what comes after the Opti. Part of what we want to do at Opti TV is to connect the class with the next steps, so naturally we went to take a look at the 29er class from the viewpoint of what kind of sailor wants to compete in 29ers. The 29er is a deceptively simple boat that requires agility and strength, and a mindset of sharing and growth. As a pre-olympic boat it's not for the faint of heart. We went over to the US Sailing Center in Miami to meet up with 2Niner Head Coach Phil Muller for day 1 of racing in the 2nd event of the Skiff Generation Grand Prix, a really great event that he has put together with US Sailing and the 49er class. It was a great day of racing, albeit light and notably it had several of the US Sailing Team members racing on 49ers and the 49erFX. We'll let you read the recap here: SGGP Event 2 Recap because we were more

Resources For Opti Sailors Looking To Take The Next Steps In Sailing

It's Not About The Boat, It's About You.  Navigating the waters post-Opti is sometimes quite the challenge because we, in Optiland, tend to get tunnel vision and only see the possibilities in sailing within the context of the Optimist class. In reality, the Optimist is the first step of many into a wide world of sailing that's out there.  Out of the many, many classes out there most of them will remain inaccessible to a fresh-out-of-the-class sailor who is transitioning from the Opti into another boat. There are many youth fleets out there and although the typical pathway is to jump into a 420, Laser or such there are no hard rules about what to do after the Opti. Here are some resources and words of advice we've put together for those who are eyeing the next steps already, whether they're reaching the age cutoff or are getting too big for the boat. Remember that because there are so many options out there, its not about the boat - its about the sailor and their kin
