In search of a perfect convex fixed blade

And yet, you can't provide it either. I wonder if you even know why it NEEDS to be a convex grind?.......other than something you've heard and now repeat?


No bother at all. I was just trying to point out that your knife might be easier to obtain if there was some wiggle room in your criteria.

But it seems that you are after the chase more than the knife, so more power to you. Best of luck to you on your unicorn hunt search.
Also I've seen several reviews of different grinds. They test it in cutting raw meat put densely into a denim sack (don't ask why 😄). The result was convex grind knives made significantly deeper cut.

That's probably all I can tell you. I'm not interested in dispute. If you say there is no difference, ok I agree
 
Interesting. Looking at it. It's stylish.
Thanks!

As for the chopping, folks, you may be mad at me, but have anyone ever seen an axe, the tool designed to chop, with blade longer than machete? I mean that weight chops, not the length. If so, we don't need the long blade, we need power hit. As I already said, the lanyard gives you that power with a leverage, as you hold the knife way too further than the normal grip, with only an index and middle fingers on a handle and the rest on lanyard. Moreover, there is even more power from a swing between the end of handle and a your fingers on lanyard.
Physics!😄
Don't be mad, just try
Although of course I agree long blades do greater chopping than smaller knives with lanyard. But it's only thanks to its weight.
I'm a hiker, I tend to go as light as possible each time. So I compromise on it using the power of the science 🙂
 
mr Doyle, when I'll get than unicorn and test it, I promise I let you know if there is no difference. I'm really curious myself

You do you man... if you like chopping with smaller blades that's great! For me, a knife that size is the wrong tool for the job and inefficient for anything other than small de-limbing or thumb size branches. I have tried with a lanyard - much prefer an axe or machete/long blade depending on what I'm chopping. Blade length isn't the question, leverage is. I'd submit that it's force that chops and weight is a piece of that equation but not weight that determines it. Mechanical advantage via leverage (the further away you are away from what impacts what you are chopping) the more power you have. A felling axe vs boys axe vs hatchet - you could make all the heads the same weight, but the chopping performance change drastically becuase you can impart way more force on it.

To each his own tho :)

Good luck in your quest! The search is half the fun!

This doesn't make sense to me? A BK2 and a wildlife hatchet weight roughly the same have drastically different chopping potential. Objects don't chop themselves... they rely on humans to chop with them - and we use leverage as a way to increase our ability, so the same effort accomplishes more.

Edit to add: try chopping holding an axe at the head vs middle vs end of haft... weight is same every time, force is different.
 
PS: I looked at the pictures thoroughly, and maybe it really has a "high convex", yet not full, obviously.
Yeah, that's what I meant. I like the N695 and N690. Tough, high corrosion resistance, holds an edge well enough and fast to touch up/sharpen.
 
Look, just imagine a thick log, ok? let's say it's already split. Now imagine we put a wedge into that dense gap, ok?
And then imagine metal ball there. Now I'll ask you, which object has a higher friction in that position?

I have spent a significant portion of my adult life in the woods/outdoors with all kinds of knives and grinds, and I can state from experience, that you will not see any difference in a full flat vs. a convex primary bevel when splitting/batoning wood.

With an axe? Yes. But not a knife.

You are getting your physics all mixed up. There's a reason why wedges are "wedges", and not balls. A wedge (or knife) by nature of it's profile, will split better than a metal ball. It has very little to do with friction - it is all about mechanical advantage of the force applied.

Sorry for the little off topic, but here is what I'm talking about. Pocket fixed blade knife Ruike f815j, about 3" of cutting edge, 105 grams or so. Take a look what that lanyard gives you, it helps cut down a half inch branch with ease. Notice that I even don't hold the knife itself!
 
That still doesn't make it the right tool for job.

I can also mow my lawn with scissors......
I can chop logs with a pocket knife, you can't. Well, sorry

That's not about wrong or not. That's about optimal.
When one is a farmer living in a ranch, having a huge shed overfilled with tools, that's ok. But can you take your machete, full size saw and enormous heavy axe to a 18 miles per day week long hiking trip with high elevation?
Come on...
 
Guys, let the man chop his log with a full convexed $140 knife on a lanyard. He doesn’t want to know the best way, he wants what he wants. He is European and he has fans. Show some respect, sheesh.
 
Man, try to get up from your couch and go up to a high mountains with 25kg backpack.
And don't forget your massive axe, lol

Again, the right tool for the job.

If you need to build an emergency shelter with a 3" blade, you are going to run out of calories and daylight before you accomplish much.

You need to balance efficiency with weight sometimes.

As a joke this is ok, but if seriously it's sad. Did I say "to baton with a ball"?
You must haven't heard what metaphor is.
Anyways...
 
Up there in the mountains, what are you going to baton/split ? You taking a saw or is somebody making firewood for you ? Just wondering.
To make fire. When it's all wet and keep on raining, you can only make fire by splitting some logs up to the dry core. I mean even if you have any kind of "dry fuel", tinder, sorry, I don't know the precise word in English for that, but you know what I mean, so even if you have that stuff you'll fail making fire 'cause all wood around is wet. You must get that dry core.

Maybe this will help to understand you folks, hiking isn't kidding 😄

Again, there's no right, it's optimal. It's what you really have.
