On another thread about the Cold Steel Gunsite, Mongomando mentioned that he didn't like the way Cold Steel did its serrations. It got me thinking since there are so many preferences with serrations, should knife companies even bother with them at all?

As I've mentioned in other posts, I like Cold Steel's serrations. They don't bump, tear or twist what's being cut. I can't think of anything a CRKT serration pattern can cut and Spyderco has tried to mitigate them much as Cold Steel has tried. It seems no pattern is universally regarded as being useful. Still, the one thing I like about CS's pattern is that it can cut paper plainly and smoothly. I've found a CS serrated blade doesn't need sharpening for a very long time and, when it does, it's very easy to restore. To prove that, I took an old, worn Vaquero 5-inch (the kind they made before clips were universally used) and sharpened it using a Lansky "dogbone" sharpener made especially for that pattern. Although the teeth were worn, and the arcs were rounded and a bit dull, it was clear the knife still would have been a formidable weapon of defense. Having no experience with the dogbone sharpener, I was able to resharpen the entire knife within ten minutes and it cuts paper almost as cleanly as a plain edge.

On my Benchmade Ascent (wonderful knife), CRKTs, Kershaws and others, I've found the serrations to be of dubious use. I've also wondered that if they're necessary at all, are they in the right place? The back edge of a knife makes them almost useless for defense and very difficult to cut anything with. Also, what is it that they cut that makes them appear on a majority of folding knives now on the market? Nautical cord and nylon rope? Try it. Seat belts? Not with those wide arcs and big teeth!

Clearly, serrations make cutting wood extremely difficult, and the Cold Steel serrations are no exception. You simply can't use them for cutting bark from wood or cutting wood into chips, etc. With the larger blade size of the Voyagers and Gunsite, the half-serrated blades are less of a problem.

So what are your thoughts? Also, if there are any knifemakers here who make serrated blades, perhaps they can share their views. Maybe I'm missing something. I will say that with their 440A blades, Cold Steel put a slightly more robust set of teeth in their serrations; not as long and not prone to chipping. That particular pattern has convinced me that even 440A can be a very viable steel when used with such patterns.

I recall Cliff Stamp's review of the Byrd Cara Cara, where he credited much of the knife's raw cutting power to the serrations. "The section of serrations gave the Cara Cara a large advantage in edge retention when cutting abrasive materials, specifically it did quite well cutting used carpet...." In short, without them, the knife's performance would have been only so-so.

Thanks!

The serrations on this Gerber EZ-Out take up much of the
blade and they do a fair job of cutting, primarily because
they're not as "toothy" as some.

The pattern on this S&W Extreme Ops hawkbill makes it great
for trimming small branches, opening packages and other tough
cutting chores, but while finer than some, it's still a bit tougher
than the pattern on Cold Steel knives.

"What big teeth you have, grandma!" I still can't think of anything
this pattern would aid in cutting, and if I could, they'd be in the wrong
place on the blade. It would require strong push strokes.

Serrations on part of a blade is less of an issue if the
blade is large enough to have a respectable length of
plain edge.

Spyderco's serration pattern is another one that I like.
 
i prefer plain edges FWIW.

i also like spydercos serrations best, EKI is also good, cold steels are ok but are really hard to sharpen, i sharpened a buds vaquero grande for him and that was a job lol,

but all in all, i prefer plain edge, though on some knives (ie spyderco police or civilian for example) PE just dont look right.
 
i hate serrations! screw them!

hehe

well ok, i like them on my bread knife

and it suppose to be good for cutting rope and cutting through jackets in SD situations
and it stays sharp way longer than a straight edge
 
I don't find them to be that advantageous over a well sharpened plain blade and for the most part many are virtually impossible to bring back to factory sharpness on your own. Most people end up ruining them anyway by trying to sharpen them improperly.

Cold steels are one that is not user friendly and even with a profiler the Spyderco serrations, which are probably the most common, are difficult at best to make perfect. Spyderco stopped selling the sharpener that does the best job a long time ago, which was a set of ceramic sticks that had the exact serration pattern of the serration on one side.

The Chris Reeve Sebenza serrations are one that I like because you can sharpen over them on a flat stone and then clean the troughs with a DMT diamond that is the thin spike shape. Shane Sibert also uses these serrations on his knives.
 
I've always thought that they were on the wrong side of the bladefor right hand users. If you're cutting rope away from you the serrations are facing down. Try it in your left hand, that's the way it should be.

Seems counter intuitive to me. But I think the first serrations were put that way for asthetics of a good promotional picture. And no one is willing to change it.

Actually, look at your Leatherman Wave. The serration is correct.
 
Are serrations needed on knives? Well, there is only one answer, and it's obviously no, of course they are not needed.

There are very few things that serrations are good at, and a lot of things they positively suck at. I have no use for serrated knives - even as bread knives, actually, as a sharp plain edge will cut bread more than well enough.
 
I think it's ridiculous to come to a blanket conclusion that serrations are inherently good OR bad. On some knives, they can be quite useful. Anytime you need to cut something fibrous, such as rope or twine, a serrated blade is useful indeed. I like a combination edge on my utility knives, and a plain edge on other knives.

I would agree, here: combo edge on utility (and maybe survival) knives and a plain edge on others.
 
Serrations ar not needed on any knife outside of a bread knife.;)

For me personally I do not like them. I find a well sharpened plain edge will go through anything I have needed to slice, chop, or cut.

I find that they make sharpening the plain section of a combo edge a bit of a pain.
 
I've gone back and forth as to serrations, i.e. good or bad.

Currently, I find peoples denial of serrations' benefits rather annoying. It is pretty well established that serrations do perform better than a plain edge at certain cutting tasks.


As to personal preference, unless I foresee using my knife for cutting some thing where serrations are better (the above mentioned carpet being one such example), I like to carry a plain edged knife.

If I'm just carrying a knife for those "gotta have a knife" moments, I don't mind a partially serrated blade.

Also, for some reason many manufacturers seem to make a plethora of a knife with serrations but only a relatively few of the model are made plain edged. If you want such a knife, its either serrations, pay a premium for less work, or go without.

As to sharpening serrations, it is a skill. Learn to do it.
 
I use serrations for two applications, cutting bread and cutting webbing.

I'm not sure how Elen cuts bread with a plain edge. I find that even razor sharp chef knives cut bread poorly compared to a well-designed bread knife.

When I'm climbing, my cutting needs are almost exclusively cutting rope, cord, and webbing. I use a Boker Rescom. The hook shape and serrated edge make quick work of webbing. The serrations are not vital, (I can cut this stuff with any of my other knives), but they help; and the blunt tip is less dangerous at a crowded anchor.

I think that serrations are not absolutely needed. They are best for specialized applications (I don't EDC a serrated blade); and belong on specialized blades. Serrations do benefit the right tasks, however.

If you talk to most people who think $30 for a 'pocket knife' is expensive, they'll tell you that serrations or a combo edge is good. That's who the mfgr's are targeting. Money and sales still dictates many things. What I think is interesting is that mfgr's still make PE knives for those who know. In other words, us.

If all I cut was rope, I'd have more serrated edge knives. But what I cut is quite a varied mix of stuff. And a PE excels at this. And I'm informed enough and I guess motivated enough to keep my PE sharp. Sharp enough to do what a SE knife will do.

So it's all in who your audience is.
 
I only have one knife with serrations, a Buck Short Nighthawk. They're good for cutting rope, or other fibrous materials, but that's about all.
 
OK, I'll swim upstream and say that I like Spyderco fully serrated blades. Cliff (voted off the island) Stamp did some testing and concluded that the Spyderco serrated blade held an edge much longder than the PE.

Except for chopping and dicing, there's nothing my fully serrated Spydercos don't do well.

YMMV - just my $.02

Except that 99% of the owners of them can't sharpen them back to new condition because they don't have a set of these. Why Spyderco stopped selling them is a great mystery. I don't use many serrated knives with the Spyder pattern, but am keeping them just in case I get one I like; even though I have had some pretty outrageous offers from Spydie afficionados for these puppies.

Serrations aren't really needed for anything. One reason production companies like them because people who don't sharpen their knives benefit from their edge retention and usefulness even when fairly dull.

I'm not saying that serrations are little more than "training wheels" for knife newbies, but I know that some people here are of that opinion.

If I remember right I read a post by Sal once in which he mentioned that they just couldn't sell enough of them at a price that could cover the costs of production.

Cutting bread is not that hard, really. I'm rather amazed at the fact that some people actually say they can't cut bread well with a plain edge. :confused: Sure, a knife designed for the sole purpose of cutting bread and only bread should do a little better in it than a knife designed for more general use, but that doesn't mean the general use knife can't cut bread well enough. Hell, if I had that logic, I would need a Lamborghini just because it's faster than my current car, even though my current car does its job well enough.

I think these kinds of things are extremely obvious. Serrations aren't needed, because you can do without them - and for thousands of years, people have. Serrations, like almost anything and everything in the world, have some benefits, and some downsides. It's just that in the case of serrations, there's a hell of a lot more downsides than benefits. And that is why serrations get a :thumbdn: from me. They have their uses, but those uses are few. That's not to say serrations are bad or good - they are what they are, extremely good for a couple of things and miserably bad for a lot of things. Whether you should go with serrations or no depends on what you want to do. It's not that complicated. :)
 
this discussion has caused me to wonder why all the free hanging rope cutting demos are done with plain edges?
