SpydercoAtlantic Salt Rust Free Serrated Edge Knife

I have a few Spyderco knives, and this is becoming one of my favorites.The blade is somewhat longer than many, but it doesn't feel big or heavy in your hand. The nylon/fiberglass handle is well suited for use in the water as it doesn't get slippery when wet the way many other materials do. I find the handle on the small side, which is a bonus if you have smaller hands or want something you can operate underwater with one hand.The knife opens easily with a single hand, although I found it took a while to break in - it was a bit stiff when new.The steel blade is indeed quite sharp and holds an edge well without the need for frequent sharpening. It's serrated and I've managed to saw through relatively thick wood and vines with no trouble at all. Best of all, as they say, it is impervious to salt water and has shown zero tendency to rust or oxidize in any way. A few times, I had it immersed in salt water for several hours, and with just a quick rinse in fresh water, it's good as new. Furthermore, I've had various chemicals, petro products, alcohols on it, and it's been completely resistant to any sort of staining.Definitely among the best in this size and shape...if you need one, this is a great product that's worth the price.

This is the BEST folding marine knife I have ever used. Period. Does not rust, anywhere, after exposure to salt water.Perfect for marine and diving operations.Mounting:For those who want to attach a bolt snap or clip, the hole in the pocket clip bolt is large enough to accommodate a couple passes of cave line [braided nylon #24/#36] to tie on anything you please. It is also [barely] big enough for a single pass of 550 paracord, if you're persistent. If you remove the pocket clip bolt [and thus, the pocket clip], the hole is MUCH larger and easier to work with.The pocket clip works fine up to 2" nylon webbing [often used in diving harnesses] and is perfect at 1.5-1.75" [rigging belts] but I wouldn't obviously rely on that for serious diving operations outside of a warm-water vacation. Tie a snap instead, and/or clip it inside your drysuit or BCD pocket! For surface work, the pocket clip is very stiff and springy, so it will be very secure on your board shorts/etc.Useful bits:The blade has an under-center action for the first 20* of opening. Meaning that, if something snags the blade and pops it open a bit, the bade will snap closed instead of staying where it is.The tip is blunted, and therefore much safer to use for rescue, extraction, and environments that are constantly moving and slippery.The molding of the grip is very good with wet hands.There are no inserts for the grip, but under normal use [not prying] I don't notice ANY flex. Pushing sideways with this knife, there is minor flex, but that is far outside the use of this knife that it is not a concern for me.Sharpening:Just send it to Spyderco every off-season. It's a few bucks. Comes back perfect.I sharpen all my plain blades, and have a serration kit should I have to do this one, but Spyderco does a far better job.USE FOR: crewing on board any boat or dive work. Surfing. Keeping clipped to your life vest. Kayaking. Cutting lines, webbing, fishing line, etc. I already have two dedicated dive knives on my rig, but can take this in a pinch should the need arise.NOT FOR: EDC, unless you literally live on a boat. The blade doesn't handle fine work well. At all. IF you choke wayyyy up on the blade, you can use just the last serration for fine cutting, but guess what, it's still a jagged finish!This is okay, because when at sea I only carry to save lives. Fine blades and tools stay in the toolkit.For EDC, around water, I would recommend the plain-edge version of this knife, as long as you are aware that it has a semi-pointed tip which makes it iffy for rescue, and often won't cut some of the new-age lines [Dyneema and Spectra] in one panicked swipe [the serrated version will].

I bought this knife specifically for a scuba trip in the Gulf of Mexico. It made it through a two tank dive, and 4 days of beach swimming, without so much as a speck of rust. Not just the blade, the whole knife... clip, pivot screws, locking bar... everything. I tried, too. It was NEVER rinsed with fresh water (there's still sand in it now, actually, a month later), and after the dives it was left in my dive bag for a few days.Anyways, that shouldn't be a surprise, since Spyderco flat out say that this knife will not rust, and they're not a company known for lying to their customers. The knife itself is a good design for a rescue knife, or a boating knife. I find myself carrying it when I'm going for multi-hour motorcycle tours into the middle of nowhere, or when I go to the lake it's always there with me. I found it perfectly suited for scuba diving. It stayed secure in my BC's waist belt, and the one time I used it underwater it was very easy to handle, with no risk of accidentally puncturing my BC.Would be a good option for a first responder, perfect for cutting seat belts, clothes, dense cloth, etc. all without the risk of accidental puncture wounds. Would also be a good option for boat knife, as there is a lower risk of drop-related injuries, and it excels at cutting rope. However, this is not a good EDC knife, and I do not carry it on a regular basis. It is a specialized tool for specific jobs, and it seems to excel at those jobs.So far, edge retention has been rather good. I sharpen it on a Sharpmaker, and it gets sharp enough to push-cut receipt paper, then stays that way for a good while. I would put it on par with VG-10.

I lost my last one. If you don't lose it it will last forever....
