A quick search at Boker shows that the Boker Plus Cera-Tac is the largest. Here are the specs;

Boker Plus Cera-Tac


Overall length: 8 3/8"
Blade length: 3 5/8"
Weight: 4.5 oz.
Blade material: Ceramic
Handle material: G-10

For a folding knife I don't know if you will find a blade much longer than this one has.
 
Thanks for the help my friend...
I realize boker advises against home sharpening, but couldnt it be done on a DMT green or finer grit "stone" using proper angle guides and H20 to lubricate?...And I mean SLOW...REAAALLL SLOW....weight of knife only as pressure...

I have tried sharpeneing ceramic blades on diamond stones. It didn't work (for me). The material doesn't develop a burr. Kyocera makes a battery powered ceramic blade sharpener that has two spring loaded diamond wheels and two angled slots.
 
That would probably get it done.

The burr concept works really great w/those big ol' ceramic sharpeners on good steels...My 18inAK by Himalayan Imports is RAZOR hair slinging, scary sharp. I developed the burr, flipped it, the edges met at about 27%---This is not a tool u wanna skrew around with..if u dropped it the wrong way the weight would probably carry it to the femor, ruin your foot etc...its a demon crusher chopping weapon.

This ceramic stuff is a man--made stone--way more refined, after boker gets ahold of it, sharper by definition--MOHS scale hardness 8.5, diamonds are a 10 of course.

If u went to the really fine expensive DMT stones, and used DMT Diamond paste stropping I dont see why it wouldnt work, other than technique.

How much could it take in an emergency SD situation--a stab, as apposed to a slash/slice?

It would probably snap..

The myans/aztecs(?) flint knapped thicker obsidian blades and used them in warfare...much less refined/weaker than alumina/zerconia ceramixxtures made now. The Kyocera kitchen knives are tough, not much of a point...as long as u dont hit them w/a hammer, chop ice/frozen meat, or thow them into the sink w/abandon...i see sharpening it as an "xtreme micro abrasion, polish flaking" idea.

I could be wrong. Theres nothing in the matl. soft enuf 2 create a burr with

I have noticed that most ceramic blades are sharpened to a more obtuse angle than a typical steel blade. This is most likely done to lessen the probability of chipping the micro edge. So the edges are inherently duller just due to included angle. The photomicrographs of the finished edge (of ceramic blades) show a very smooth and straight microedge. I heard somewhere that these smooth edges are produced on a rather coarse diamond wheel. Go figure. It's all in the wrist LOL.
