hey everyone,

the aqua salt is a pretty good knife. i bought it a few months ago in a plain edge, yellow handle verson and i am fairly impressed with the corrosion resistance of h-1 steel. i mainly use it as a tackle knife for fishing. i live along the california coast and spend a lot of time at the beach shore fishing, camping, and making bonfires. the aqua salt also works as a really good outdoor food preparation knife. sometimes it feels more like a kitchen utensil than a outdoors knife.

what i really like about this knife is its ergonomics. the knife feels very comfortable in the hand and the angle of the handle and blade are perfect. the textured grip feels very secure even with wet hands. i've always been a fan of solid one piece knife handles. i never caught on to the screw-on panels style that many knives have these days. i prefer not to worry about rust or other corrosive substances working its way between scales and screws; the fewer the parts the better with less maintenance. it batons through store bought firewood fairly well to make kindling for beach bonfires; possibly my favorite outdoor activity of all time. there's nothing like camping out on the beach during the summer in california.

i will say that i have three issues with the aqua salt. first, i feel that the strength of the blade and user confidence would increase greatly if the blade was 4mm thick instead of 3mm thick. the blade does feel a little thin for its size. second, the hole in the blade does concern me when batoning. it doesn't have any purpose other than asthetic appeal and design. i don't believe it's there for a lanyard since there's one on the end of the handle. by far i'm no expert on knives or knife design but i feel that removing a rather large piece of metal from what seems to be the blade's strongest spot is unnecessary. and third, h-1 steel seems to be a bit softer than other stainless steels in my experience. the blade scratches easily when in use and even when sheathing and unsheathing. i find that strange since the sheath is made of some type of plastic. however, it does sharpen easily and holds an edge fairly well. i believe with these improvements the aqua salt would be a perfect knife.

overall, the aqua salt is a great knife for beach bums or for someone looking for a knife that fits perfectly well in the kitchen as it does in the campsite. it has become the favorite in my collection. i'll probably buy some as gifts for some of my salt water friends.

i would like to hear about other opinions and personal experiences anyone else may have with this particular knife. please share your thoughts.

thanks,
b.n.f.
 
Nice! I'd love to see some beach camping pics, and of your knife :)

as far as the soft blade steel... It is common in all knives that are better at corrosion resistance that the blades have less edge retention. However, H1 is a steel that will NOT rust and still has better edge retention than a lot of other corrosion resistant steels that will still rust.
 
Also H-1 is not given a traditional heat treatment due to its low carbon content. Instead, the edge zone is work hardened by the grinding process. This is why Spyderco makes no full flat grind H-1...both sides of the blade must be ground simultaneously, and a machine that can grind a full flat on both sides at the same time...well that just doesn't exist at the moment. However it is this work hardening gives the knife a soft spine and a hard edge, making it one of the most impact resistant stainless steels on the market for knives right now. :)
 
I'm a big fan of the Aqua Salt. I've installed one in the Mossberg JIC kit that resides under the middle passenger seat of my Zodiac. A Mossberg Marinecote 590A1 twelve gauge, a corrosion-resistant fixed blade, and other odds and ends are certainly a good ways towards being prepared for any waterborne emergency.

The Aqua Salt definitely gets the thumbs up from me.

:thumbup:
 
H1 is a softer steel and scratches on almost everything. If it bothers you, a buffing wheel and a dremel will get rid of the scratches just as easily.

Being totally rustproof with apt levels of edge retention makes H1 a superior steel for a dive knife. Because of its unintentional differential heat treatment, it is also one of the more impact resistant steels around. Overall it makes an excellent knife.
 
Perhaps my definition of "batoning" is different than yours but using an Aqua Salt for wood-splitting duty is pretty abusive (for any knife really).

If you are looking for a more vigorous chopper for heavy duty stuff the Rock Salt is a major league coconut opener :)

Unless you wear a hockey mask and use a 3lb sledge hammer, it's not abusive to a fixed blade. ;)

The Rock Salt is a really nice knife. I had a chance to handle one and it would be an excellent camp knife.
 
I'm not getting great edge retention using mine as a kitchen knife. I've read that edge retention increases with use and/or sharpening as the edge is work hardened. I'm hoping to start seeing that benefit soon.

Yes,That's true.I have a pacific salt in serated and I've sharpened it up about six times.After the thrid or forth time the edge retention goes from about aus8a to vg-10 or even a little better.But sal said the serated models work harden much better then plain edge.

I'm glad your not the same guy in the log cabin with a rock and a thick grizzly accent, lol.
