convexing

well the way i see it, when you cut into anything newtons 3rd law kicks in so it immediately wants to spring back into its old position so if your batonning into wood it wants to bind up along with the back pressure from the uncut wood, the shaping of the convex edge allows for that force to be dispersed and splits it into the opposite direction, and when it gets far enough down it will either bind like on a hollow grind that doesnt create a big enough gap for the material to stay split while both scandi grinds an convex do simply from spacing, and i think its really more preference of convex over scandi, the only difference i could see would b that there are less harsh edges on a convex edge just giving very slightly less friction
 
the angle is larger so it wouldnt trust me ive felt the same way until i was cutting rope all day long and my hollow grind knife rolled on me and the convex cut it like it was hot butter
 
What convex knife do you own that doesn't feel sharp?

A scandi ground knife will usually bite deeper than a convex knife. However, it all really depends on how steep the angle is at the edge. I have convex knives that bite just as good as some zero edged scandi knives.

The convex edge also has more steel behind the edge, typically making for a stronger more durable edge.

By the way, is there something wrong with your caps lock?

And congrats, I think 17 threads in a 15 minute period is a some sort of new record..

No need to get all upset, it was just question? Relax:thumbup:

What convex knife of yours doesn't feel sharp?

If the edge is a little thick, you can always take the shoulders down a bit.
 
lol damn, coincidentally he turns out to have one hand. :eek:

I agree with what Tony is saying. In short, the scandi will bite deeper, the convex will hold an edge longer.

People who baton like a maniac (who don't want to bring an axe for weight reasons or for because it simply isn't their style) are definitely going to lean more towards convex, people who leave the hard work to an axe or dedicated chopper will probably be best off with a scandi. :thumbup:

Hey Cody, does that mean you're going to start carrying and making convex knives???;):p

Just kidding bro, It's good to see you posting. I hope you are feeling better!

Thanks Tony, I'm feeling a bit better now! Anxious to get back in the shop full-time. :)

And yeah, I'm going to begin experimenting with convex, scandi-vex, and flat grinding soon. I have a funny feeling that my personal favorite will remain scandi, but we'll have to find out I guess! :D

+1 :thumbup:

You type fast for someone with only one hand! :D Just kidding, man.

I've noticed the same thing about convex edges. They don't 'feel' as sharp as a conventional edge for some reason. The first time I held one I was pretty skeptical, until I started actually using it. Even though it didn't seem as sharp, it glided through wood, both green and dry, as well as fruits and vegetables. I've converted a few of my knives into a quasi-convex edge with the sandpaper-and-mousepad technique, and they work really well.

Is it just 17 threads? I was wondering if there was some contest about the most threads that I missed somehow. LOL.

Too funny, no offense man just a good line. :D This is where to ask those questions. :thumbup:

I'm glad to have clicked into this thread. I convexed a RAT Izula that I stripped and worked on convexing but for the life of me thought it was some mojo that was outside of realm of skills.

Tossed the mousepad and sandpapers and put a shaving sharp V grind on it cuz it just didn't feel as sharp to the touch as my factory Izulas. I knew the edges met (under magnification) but it didn't feel scary sharp. I should have done some comparison cutting with it.

I'll have to start over again and give it another whirl. :thumbup:
