Lets see your best cutter...I'm talking high performance cutters....(Thin is IN!!!)

mmm Agreed you CAN get convex to the same degree of sharp as any other type edge.. but if your INTENTION is to have minimal maintenance, it won't be at the ultimate sharpness possible.

i'm both a freehand sharpener and way too obsessive to stand for a dull edge.. and way too lazy to keep my kitchen knives sharpened to bragging sharp. it takes about 3 months for me to work through my knives in rotation (over 50, probably close to 100 kitchen knives) and I'm satisfied with a 2000 grit sharpness for my working knives.. the few knives that demand that scary sharp edge are exceptional steel, and i tend to avoid using them because of their maintenance requirements. I take all the knives to that level ONCE.. but maybe 1 out of 10 gets the full treatment every time. The others I sharpen on a blue belgian and touch up on a ceramic rod till they get the least bit dull, then i use other knives till that one goes back in rotation. No way i'm going to sharpen them ALL to the ultimate, I don't need it. one of my favorite 'scary sharp' knives is a clone sabatier 7" santoku, china made, SOME sort of particle steel, CPM 440C I am guessing(?) .. VERY sharp knife, VERY surprising to find particle steel in a clone, must have had extra somewhere? There are some surprises to be found in the discount bin, i was shocked to find out what 10$ had bought. Happy shocked but shocked. I now own half a dozen of those particle steel clones after chasing through every discount bin I could find within 20 miles.. they sure cut nice. touch up on blue belgians, finish sharpen on champagne, strop on paper .. yeah, paper.. back books.

it works for me. :)
 
Heres my ZDP Acies Edgepro'd to 18* Sebenza Edgepro'd to aprox 22*


All of my knives must pushcut newsprint before they leave the edgepro.

Sorry for the crappy cellphone shot.

No pics, but a Opinel which received full-convex zero edge and thinning from sandpaper is currently my top contender.
 
Are there any blade steels particularly suited to ridiculously thin edges like this?

O1, M2, CPM M4, F2 (if you can find it), 1095, 52100, 1075-1084, L6, W1, W2, 12C27, 13C26, AEB-L, Hitachi Blue, Hitachi White, and more. Heat treat has to be just right though.
 
One of my recent projects that some of you have already seen elsewhere.

ZDP-189 reprofiled by hand to 4 degrees per side. It is not super pretty, but it performs very well for me!

This new Spyderco angle gauge is pretty neat, but it only tells me that it is somewhere between 5 and 10 inclusive. I used a micrometer to verify that it is really close to 4 per side and 8 inclusive.
