Efficiency of edge types

#1

Post by Outremere »

I have used these blades for years and have taken them around the world. I need opinions on which edge type is most efficient, saw, plain, or half and half. I’ve used the saw edge in jobs where I might need a quick powerful emergency slice but prefer plain for general purpose. As to half and half, I just don’t see the logic of it; am I wrong, I’m here to learn.

I'm certainly no expert, but I think the answer you're most likely to get here is: efficient for what task?

Just carry one of each and call it a day. I do this, and I do not like combination edges.

Depends on what you're doing. I'd rather cut rope with a serrated knife but I'll pick a plain edge to mince garlic.

If your aim is a neat and clean separation a well sharpened plain edge is the way to go. If you simply need something separated quickly and efficiently, serrated is a great choice. I’ve been EDCing the SE Para 3LW since it came out and I’ve very rarely wished I had a PE in my pocket.

Yea, the answer as always is it depends, but I won't take that easy of a way out here.

The two main questions to me are what are you cutting, and how good are you at sharpening?

If the answers are, a variety of things, or really, if you're not a professional role cutter, and even if you are I'm not convinced it matters, and if you are reasonably proficient at sharpening, then plain edge is the clear winner. I'd caveat the last point by saying if you are exceptional at sharpening serrations then it levels the playing field somewhat.

Basically I believe a well sharpened plain edge cuts pretty much everything better than a serrated edge, but if your not that great, serrations will stay sharp longer, and cut much longer if you don't mind applying a lot of force.

Plain edges also can be tailored to cut fibrous materials better by manipulating the edge finish.

My recommendation is plain edge, and if your not a skilled sharpener, become one.

Sharp SE generally require less force than sharp PE if we're talking factory angles. They come ground much thinner.

Welcome to the forum!

I tend to carry one of each. Plain edge and serrations both excel at different tasks, and I have various tasks come up in a normal day.

I've come to the determination that if I could only have one blade to survive on I would take a serrated edge. Because a high quality serrated edge can do more rough work than a plain edge can.

Now that isn't saying that a plain edge doesn't have certain advantages because it does. But if I was stuck in a survival situation I just know in my gut that a serrated blade could do more vital jobs in a pinch than any other type of edge.

This to me is one of the main reasons I want to see the return of the C-44 Dyad. Because a folder with one full plain edged blade and one full Spyderedged blade just makes a lot of sense.

A decently sharp serrated edge will out-slice any hair whittling plain edge knife. It's just physics at play. There's a reason why sharks, most reptiles and the extinct theropods had serrated teeth. They just cut better.

That being said, for general edc tasks I switched to SE for a few months now and I never looked back. I love my SE Pacific Salt. But, serrated is out of the question in my kitchen, bushcrafting or taking apart game. The cut is cleaner with PE and push cutting against a surface isn't very effective with SE edge.

JD, how are you going to sharpen that serrated knife in the wilderness without any sharpener? Serious question, bro. Much as I like serrations, I'll take a PE for that. I can sharpen them on a lot of things, and have done so.
- best wishes, Jazz.

Carry a piece of sandpaper or an individual sharpmaker rod. You can baton a small stick in half and wrap the sandpaper around the corner of one of the D shaped sticks you split. If you can field sharpen a PE knife on a river stone you can pull this off.

I have nit been too logical, it seems. On my folding knives, EDC, etc. I have tended to want plain edge blades. On my kitchen knives I will get serrated blades many times. So, based on my kitchen experience I should opt for more serrated edge edc knives as they do cut well if sharp.

Good points.

I agree, and I just happen to have an old pic I pulled up for another thread, that illustrates this with a tiger shark's tooth:

(The rock’s a piece of flint core encased in marine concretion which was thrown up onto a beach in southern Australia.)

Looking at the tooth, it makes me idly curious about what a serrated edge might be like with serrations of different size - getting progressively larger or smaller, as they follow the curve of the edge.

That's an interesting question Jazz :) >> that's why I have a wide array of sharpening gear I've got stored up. However a Spyderedge or most other serrated edge patterns will be adequate performers long after most plain edges get relatively dull. At this point in time I have a ton of different types of sandpaper I could use in a pinch. But I do need to focus on something more portable I could travel with.

But I do like your question and that's something I'm going to have to look into as far as finding something to sharpen SE blades if stuck in a disaster situation. But as of now I have a huge box of small, portable sharpening tools I've got for my survival/bug out bag. Actually I'm hopeful I'll never be in that situation>> but your question is one that I'm going to have to look into.

I don’t recall if you have one JD, but I find the edges of the Doublestuff 2 to be an excellent portable handheld SE sharpener.

They’re easy enough to carry in a pocket, or stash in a go-bag or car glovebox.

Also, if anyone reading this accidentally breaks one of their Sharpmaker rods, the upside is the smaller pieces make handy little pocket stones for SE touchup.

I have a couple of bits of a broken UF rod that I use a fair bit for handheld SE honing.

It sounds like you really need to experience a truly sharp SE knife.

Also you can change the edge finish on serrations the same as you can plain edge.

I prefer a combo edge but sadly it is lacking in models I like.

It covers the best of both worlds.

I have noticed serrations work better with man made materials plastics rope and if you do not mind dirty cuts and leaving cardboard junk on the floor.

I have noticed serrations work very well taking apart a cooked Chicken and other cooked meat with bones you can go sideways with the blade and strip the meat off the bone nicely.

I have Noticed Plain Edge is all around useful and provides much cleaner cuts and tend to carry PE more than SE.

Would like a combo edge Wharncliffe Delica and Endura

Yes, I like combo edges, too. I find them very useful on blades of at least 3”.

Honestly it sounds like this thread is "let's compare a dull serrated knife to a sharp plain edge knife." Sharp serrated knives don't make messy jagged cuts that leave debris on the floor. They can push cut through cardboard and leave 100% smooth edges where they cut.
