Why aren't Beckers convexed?

I have read a lot about the convex edge and how it is so great. I am considering convexing my BK14. My question is.. if the convex edge is so great why arent the Becker knifes convexed? My only guess is it would be too difficult to do that for a production knife.

Bingo.

A true convex grind(even just a secondary bevel) must be done by hand and takes quite a bit more skill to do well than just merely doing a small V bevel on a hollow or flat ground blade.

Most of the grinding done on Beckers is done in a CNC controlled mill or grinder. That's why they are such a good deal for what they are. If you want them convexed at the factory, be prepared to pay well over $100 for them.
 
All of the above makes sense. I'd love to hear Ethan's take on convex edges in general, though....
 
Mine are! Ha, just had to be an ass. Anyway, what has already been said. I did mine myself. It takes time and patience. Neither of which I have much of.

All my beckers are convex, I usually convex them right out of the box but decieded to give the V edge a go...It sucked ass. Haha, convex edges are WAY better but harder to sharpen in the field. Anyway, as people have said it'd cost alot more to make convex Beckers. Sandpaper and a strop is the way to convex.
 
I convexed my 14 and really liked how it changed the performance. I say go for it.

A nice mirror polished convex is a beautiful thing.

That 14 looks really nice :thumbup:

I went ahead and stripped my 14, I didn't want to worry about sanding the coating. I will be going to the leather store tomorrow to either buy a leather strop or get the materials to make one.

When doing the convexing, I am thinking about starting with 220 grit sandpaper, then moving to 400, 600, then 800. Does that sound good or does anyone have a better suggestion?
 
see Jerry Fisk convexing on youtube!!!Convex all your beckers, its not that hard, I fully convexed some of my blades and it drastically improved the performance.Or you can just convex edge....v edges are ok for small folders.....although I convexed some of those 2.

I use 80 grit to start with and then 120, 180, 400, 2000 and strop. 220 you'll be there for along time...

per the OP...

it's a matter of cost and production...

it would cost 2-3x as much, they couldn't make as many as fast, and they wouldn't sell :)

let's face it, a lot of people buy Beckers because of the value, despite the fact they are clear the best :D :D :D :D :D

we've already seen what happens when a Becker is over $100, slow sales, except for the BK77 limited. you guys are clearly about shopping for value.

oh, and the factory edge is pretty darn good, so, well, there you go.
 
V grinds are better and easier for the average joe to use and sharpen. Plus, there are tons of systems out there, that will accommodate a v grind, but not one that will accommodate a convex.

I like convex edges, but I have found that when those that say a convex is easier to sharpen, I don't think it is. MHO here fellas, lets not start a skirmish apout. I been sharpening v edges for over 20 years, and I get mine sharp, very sharp.

Its all about edge symmetry, and its not easy to do that with convex. There is tons of posts and theads debating the two, so we won't get into here, I just prefer v edges, and so do most manufacturers.

My BK2 and BK11 have convexed edges - the rest are more or less at the factory angle. Get some wet/dry sandpaper and watch a movie. Tada - convexed.

also, there's many kinds of convexed edges..

imho there's a reason many an axe has one. not all do. they should though ;) good for chopping and such.

they don't feel as sharp, and for some, that seems to be important ;) they can still pop hairs though, esp if you add a micro-bevel?

but eh, sharpening and edges and profiles - wank wank wank ...

as i said earlier, the main reason? labor intensive and most KNIVES don't need it. ultra choppers should imho, and many do.

one can convex the edge nicely on a Becker - good enough more our purposes, even more so, and Fisk the high points if you chop/split a lot.

15 minutes on a $4000 machine, but you're eyeballing it and doing it by manual labor.

worksharp does it pretty good enough.

I discovered convex edges by accident in my early teens while resharpening the knives I was using to help butcher and slaughter.

IMO they're not easy to sharpen per se but easier to maintain. Once I get my convexing where I want it - I go for a short convexed edge rather than longer - it's really simple to maintain than edge with a decent sharpening steel.
