Next to various types of ceramic knives the company also seems to make a host of other specialty kitchen knives from various space-age materials: http://forever-k.com/en/ceramic/
Anyway, the 3 ceramic knives were tested on wear resistance, and the (much) cheaper Forever knife seemingly won by quite a margin regarding that aspect:

Now i know that wear resistance does not equal edge holding (especially with ceramic knives), but who knows ?
Maybe they're on to something.
Since i sharpen ceramic knives for others from time to time (and the two tested Kyocera models have always ranked the highest for me in the edge holding department so far), i became a bit curious about the Forever knife.
So i ordered the exact SC-16WB model that was tested from a Japan based E-Bay dealer for 45 US dollars including shipping to the Netherlands, and yesterday it arrived:









Specs:
Ceramic knife for right handed use (non-logo side is flat, while the logo side has a wide saber grind and a 70/30 edge
Overall length: 10.9 inch (27,6 cm)
Blade length: 6.3 inch (16,0 cm)
Blade material: High Density Zirconia
Blade thickness: 1,43 mm
Thickness behind the edge: 0,61 mm
Factory edge angle: 26/27 degrees inclusive
Edge finish: rather coarse with lots of bite (my estimate: somewhere around a 1000 grit)
Sharpness: Can shave my arm- and leg hair with the growth, not against it.
Not a single microchip can be felt using my nail, or seen through my Victorinox magnifying glass
Handle material: black plastic
Weight: 83 grams
I'm going to use the knife the coming months for standard kitchen duty, mostly to see how that rather coarse factory edge will hold up.
When the time comes i will experiment a bit with resharpening and write about my findings in this thread.
