Convex grind: AMAZING!

Okay. I have been playing with my convex ground BRKT Fox River, and my custom Gossman PSK Jr., both convex grinds.

Once I went convex, I'll never go back. I've been bitten more by these two blades more than any other blades in my years and years of "knife-knuttedness."

I was playing around with snap cuts through brown paper grocery bags, using the Fox River. It sliced through full length each time (the bag was freestanding, held only at one corner by me).

As it got close to my "holding hand," I laughed to myself - "What if I happened to hit my holding hand with the blade as I quickly sliced off pieces of bag?"

Well, I found out. I felt something touch the thumbnail of my holding hand. I laughed instantly - thinking, "Whoa! That was close!!!!" Then I looked at the thumb. The blade sliced cleanly through the thick thumbnail down to the sensitive skin underneath. Blood promptly flowed out through the thumbnail.

I must admit, I let out a quick "little girl" high-pitched scream when I realized it. I ran to the band-aids and closed it up immediately, realizing that the little-girl scream was unnecessary. Although I cut myself badly, I would certainly live through this. So, I laughed again.

I can't wait to finally play with these knives in the woods.

I am such a p*ssy. :D:D:D:D

But, I now view any blade without a convex grind as "not a real knife." This is not an official opinion, just a personal amazement at the geometry of a convex grind.

I will never own a knife again that does not have this grind. It is stunning in its cutting power.

The Fox River, with its convex grind, cuts more powerfully than any large blade I have ever owned. It IS a large blade - it's the superior of a 9-11" big bowie or other large knife. But the cutting edge is only 4".

The tiny Gossman PSK, Jr. also is a workhorse. It looks like a paring knife to the layman, but it cuts, splits wood, and generally outperforms most of my 4-6" knives.

My thumb verifies my opinion.

Wow!!!!!!!!!!!!!!!!!!!!! :)

Once you go convex, you never go back to bevel. :D
 
Yeah convex like Bark River does is really great.

BRKT has given the public what it wants: A good knife that is sharp and easy to keep sharp.

Given the crappy grind on about 90% of production blades Bark Rivers grind is like a breath of fresh air. A company that remembers that knives are for CUTTING first!:thumbup:

What! No bloody pics. :eek: :D
 
you cant beat a convex thats for sure. i gave a friend of mine a convex ground knife that he carries along with his backup gun. he said its one sharp mother. the bowie that cut the crap out of my right hand was a convex grind. it was so sharp i was actually scared of it to the point i sold it.
 
speak it man! i was not familiar with convex until i got my brkt TUSK. i used it for about a week in the warehouse and i thought it "felt" dull. i think this was because running my finger over it i could not feel that second bevel (no duh!). so i took it home and sharpened it with a normal 20deg. bevel. ...mistake... i spent this afternoon afternoon getting my TUSK back into the shape it was screamin to be -convex. oh the glory! back where she belongs!

but hey, get lost once and you never will again.
 
Excuse my ignorance, but what are "snap-cuts?" I've heard that term used before, but never figured it out.
 
Chuck Buck, my Fox River shaved better than any razor I ever owned when it first came in the box.

k-spar, snap cuts are when you hold the knife between thumb and forefinger, and use the other fingers to sort of "snap it down and through the item you are trying to slice. It uses less muscle and more momentum - kind of like when you throw a baseball or wind up a towel and whip your arm to thrust it like a whip. You keep your wrist loose and fling the blade.

Okay, you sickos. Here are the bloody pics. I even pulled the wound open to show it better. it's not that dramatic, but amazing that the little 4" blade so easily sliced through thumbnail.

Threads like this are really not cool :mad:

I've been struggling against the temptation to get a Barkie for awhile and this is really not helping :grumpy:
 
Theo,

This is exactly WHY a Barkie is so awesome. I am in awe of this little knife. it's thrilling how well it performs, even in spite of my stupidity! :)
 
The one. You should definitely not go look at the " how sharp is your knife" thread I posted. That was a 4 inch convex ground Barkie Bravo 1. 14 stitches later I'm doing better. I can say I love the convex grind and will never go to another one
 
cmgray, isn't it amazing how when a knife bites you like this, you love more rather than less! :D

The Fox River is a great all-around bushcraft knife, but it was designed as a hunter/skinner first. It sure can rip thru nails to the flesh!

Sicko that I am, your thread made me now want a Bravo 1 as well! :D:D:D:D:D:D
 
I have rule: once a knife bites me, I NEVER get rid of it. EVER.

nice pics brian!

STOPPPPPPPPPPPPPPPPPPPP
I've been drooling over the Bravo 1.

Glad you're doing better.:)
 
I will have to agree, convex grinds are great!!!! I have loads of other blades, but the convex grinds are proably the most easiest to maintain no doubt.
 
Welcome to the club. Now you can throw away all your useless sharpening gizmos.

Not only is the convex edge sharp it is in accordance with nature. Mankind thinks up things like bevel angles and other nonsense. Nature abhors straight lines and is all about curves. :thumbup:
