Spyderco’s Mantra 3 – In Case You Are Looking For A New EDC knife

U.S.A.-(Ammoland.com)- At SHOT Show 2019, Spyderco had a few new models on display. One of them that caught my eye was a Spyderco Mantra 3. My first thought was a carbon fiber Delica model, but it is really so much more under inspection.

The Mantra Model may be a few years old, but this model featured a carbon fiber/G-10 laminate material as handle scales instead of titanium, which makes for a lightweight and attractive pocket knife. Particularly if you are looking for a new EDC (Every Day Carry) knife for some reason and don’t want to break the bank or worry about scuffing titanium handles or bolsters.

The Spyderco Mantra 3 has all the hallmarks of a good EDC folder.

There have been a few other changes as well to this new model, besides the handle material. The first is the leaf-shaped blade that has a small almost recurve shape toward the rear of the cutting edge.  After examining it I deduced that this had to be ground this way in order to work with the compression lock and the flipper tab.

A slimline reversible wire clip secured by a single screw replaces the three-hole clip that used to be used on all Spyderco models. Some collectors do not like this type of clip, but as someone who uses and carries knives, I honestly prefer it. Spend an afternoon in a gun shop, sporting goods store or on the range and start counting pocket clips. Sometimes you can even identify the knife in question. The wire clip blends in better and can more easily be mistaken for a pen or other innocuous device in the pocket if it is even noticed at all.

I have been seeing this clip appear on more and more knives from Spyderco in the past few years. All I can say is that whoever came up with it is a genius.

The Mantra 3 can pe opened in two ways. The first and most obvious is by using the trademarked Spyderco round hole in the blade. This was designed by Sal Glesser, the CEO of Spyderco and has appeared on every model in one form or another ever since its debut nearly 40 years ago.

Option two for opening the Mantra 3 is (as we mentioned above) by means of a blade flipper. In testing the flipper (because my biggest pet peeve is a flipper that does not flip!) I found it smooth and extremely consistent This has to do with specially designed ball bearing washers between the blade and the stainless-steel liners.

The Spyderco Mantra 3 is lightweight and carries well.

Spyderco probably could have made millions of these in either a lock back or liner lock form and people would have gobbled them up. However, in this case they installed their compression lock system on the spine of the handle. This lock captures the best aspects of the liner lock and the standard back lock that has been in use for nearly a century on most pocket knives.

Spyderco’s compression lock combines the best qualities of the liner lock and the lock back.

For the blade, Spyderco chose a 3.24″ leaf-shaped full flat ground blade made from high-performance CPM S30V particle metallurgy stainless steel. It is razor sharp out of the box and is one of those steels that most enthusiasts seem to prefer these days.

I have to say, when it comes to materials in a factory knife, it is hard to go wrong with carbon fiber/G10 laminate and S30V steel. These are typically used by custom knife makers instead of factories where knives are mass-produced. In this regard, I might have preferred to see full carbon fiber scales instead of the carbon fiber laminated on top of the G-10. Although this would have added to the cost of the knife.

That being said, while S30V is good steel that was designed specifically for knives, it is not my favorite. I prefer the various tool steels for my knives, but I live in a desert and do not have to worry about rust and corrosion the way some people do. If you are going to go with stainless steel in your knife blades, S30V makes for a good one.

If you run into the same problem that I have with regard to S30V and resharpening, my advice is to maintain it on a regular basis a bit more often than you think you may need to. One of the best ways is to invest in a Spyderco Tri-angle sharpening system and touch up the edge a bit. I have been doing this on all my S30V blades the past few years and it makes all the difference in the world.

Hopefully the slight recurve toward the rear of the edge does not get in the way of smooth sharpening!

Meh, the flipper is sorta like tits on a bull because it’s probably faster flipping with the thumb hole. I dig the carbon fiber, considering my wallet and holster is carbon fiber. S30V is a decent blade steel, but I don’t think at 150 for what it is people will be buying. I’d sooner buy a Delica or even a manix at that price point.

Cheap wire clip and made in Taiwan for a street price of $150? No thank you! I’ll buy an American made blade for that money.

Chuck Brant

Not half as nice as the Saga 5. The mild recurve, flipper tab hit you finger on close, and a detent not great for flipping. Spyderco is not awesome on flippers. I’d save the money and just pick up a PM2

Their off shored knives are typically $40-50. No way id pay $150 for a Taiwan knife. Pure corporate greed.

Taiwan is our toughest, most technologically prepared ally against Communist China and worthy of our support.

The Green Watch Dog

Lets support companies such as Spyderco! Their products are made in Taiwan. Taiwan has the toughest gun control laws in the world. Owning a firearm here is illegal and you can face the death penalty. We certainly don’t want to buy American made knives such as the company that helped law enforcement chop up guns that were confiscated in criminal activity. Ted Nugent and other extreme gun activist would endorse this post.


TGWD, You realize Spyderco is based out of Golden Co, with roots in Japan? Take a look at the Para3. I’m all for supporting American made, and 2A friendly companies, but in the interest of providing a competitive priced product companies are out sourcing everywhere. I’d rather buy a Taiwanese made knife from an America company than one cutting freedom sticks for any reason.
