Why that grind if......

Lol

Prepping some wood for this mornings favorite fish spot. The fire makes it more comfy on these cool mornings by the water, smoke keeps the bugs down too. The wild life was off the hook this morning.

That's my hollow ground chopper splitter. Twisted up dry ash is no match for it.

Here you can see on the finish wear how a hollow grind creates less friction while batoning the edge and the flat part of the blade keeps the grind from dragging and causing friction. I've only had it 2 weeks and 4 days and it's done much more than some peoples knives do in years. Just because the final edge is actually convex because it's pretty hard to not when you free hand does not make it a great chopper/splitter, the hollow grind does that. Answers the OPs question really, but don't mind me, I only know it from using my knives.

Good to see so many fingers were pitter pattering while I was out fishing.

Kinda makes me feel good I can actually display to the OP what I am talking about. I'd love to hear why you use what you do, how much you use it, what kind of wood and even the grind would be nice to know. Instead all you do is try to reinforce as best you can (not doing to well at either buddy) I am wrong, because you said so.

I love the 1095 in that blade too. Perfect heat treat on it. Holds the edge fantastic. Just took about 3 minutes of my time to restore it to razor sharp. In my opinion, it's the best super steel being made today. Tear up that opinion right there, your one track you're wrong posts are getting boring. But tie it into the OP so we keep it on track.

I never said you were wrong. I said you were acting like a _________ <fill in the blank>. Big difference.

But please, regale us more with tales of your unrivaled experience, unmatched expertise, and your mighty Schrade.

Nope, it's your turn. Show us them well used flat grinds. with your 36 years (lol) of use they should have some pretty good wear, even if you got them 2.5 weeks ago like mine. That is your contention after all.
 
Whelp, this one's headed for the lockdown.

It wasn't marcinek that said he had 36 years experience...seems to me you don't have quite as much internet using experience :eek: :D

Just curious, as I wasn't able to find this on any of the major retail sites, or any of the reviews I've found so far. Also, all of the video "reviews" i saw didn't have clear enough point down shots to tell just by looking at it. But is that schrade actually a hollow grind?

One reason I ask, is that my Bk2 showed almost identical coating wear patterns (before I stripped that portion of the blade), and it is a saber grind.

OCNLogan, prepare to be told that you're wrong and obviously don't know anything about grinds, right after Boring here tells us how his 11 year old son knows more than any of us do (again).

That's the best I can do. I only have the camera that's on my phone. I snapped it when it was a little not centered, but you can see its hollow ground.

I have seen more than a few saber grinds with an ever so slight hollow touch to them. I bet it would create the same less friction scenario as well.

I mentally prepared myself before I posted :p.

I was just hoping no one made fun of my obviously horrific practice figure 4 trap, and paid attention to my BK2's coating loss pattern :).

Luckily I think elsewhere in the beginning of the thread the OP got their question answered pretty well, so at least there is that.

Thanks for the photo, that does indeed look fairly hollow. But really, I couldn't find any info on if the Schrades are hollow ground or not (at least not in the 10-15 min I spent searching, to make sure I didn't look like an idiot online), so I was just curious.

And I think your statement about saber grinds having slight hollow shapes is really common. I asked Paul Tsujimoto(sp?) in the Kabar forums "Ask Toooj" thread about a similar finding I had about a Full flat ground blade. His response was that its pretty normal for flat ground knives to be ground on large diameter wheels, giving them a bit of "hollowness" that might become evident when you try to say... polish them on a piece of glass (what I was doing). So I'd imagine that sabers are frequently ground the same way.

Anyway, thanks for clarifying :).

As always, I learn something from you. I only posted what I have observed (people around here don't like that lol), good to know I wasn't imagining it or handled a bunch of poorly ground flat grinds.

Always a pleasure to converse with knowledgable experienced enthusiast. I'm just a knife user who has keen observation skills, probably better than my knife skills. Enough for me to make the right choice to make desired tasks easier though.
 
On spydercos and this may have been mentioned already but I like their sabre grind over ffg. I'm al. Out certain in my use that the sabre grind prevents the substrate that you are cutting to not bind to the knife the way FFG's do.

Junglas is pretty much flat ground (well, really high saber, but pretty damn flat). :)

Shelter was 100% built with the Junglas. :thumbup:

Didnt you read the thread stabman? Boris says you are doing it wrong. You probably would have had two shelters had you been using a hollow ground schrade.

That was good for a laugh. :D

Thickness behind the edge--and how far past that it remains rather thin--will dictate how deep penetration is with each chop.
A flat grind or a hollow grind can do that; hollow grinds aren't all very thin...the Wilson Combat Camp Knife I traded to my father is rather thick.

A convex grind on thin stock would bite deep as well...there's no magick to it, just physics. :cool:
