I got a 780 triflex the other day and when I first got it it was extra dull and it had unusually uneven grind lines. So once I fixed the grinds and sharpened it to hair shaving sharp, I started cutting up some light cardboard (the box it came in actually) to test it, only to notice that the edge had become so badly damaged within the first few cuts that instead of actually cutting the cardboard, it was tearing it instead. So I sharpened it again and grabbed a 1" thick piece of green pine, and before I stripped 6'' of bark off, it was dull again.

Ive owned about 10 carbon Mora knives (2 triflex) and this is the first time this has happened. Im guessing that this blade was annealed for the soft part of the triflex and then they just never hardened the edge up or something. It really sucks.

Heres a pic. There is no 2nd bevel, that's the damage after cutting some card board.

Looks like my Opinel. That one has a bad heat treat also. Not much you can do, unfortunately.
 
Something weird is that I read somewhere that the steel sometimes softens from polishing and that it takes a few sharpenings to get through it sometimes. So I sharpened it and took about 1mm off and now it holds an EXCELENT edge. I never knew polishing a blade can heat it up that much.
 
You know mine was like too. Until I took it ans sharpened it on diamond stones. First the course, then the medium, and finally the fine. I sharpened on the course stone to remove the most I could, then did the same with medium, and so on. Now the edge is sharp and holds a heck of alot better. When it dulls, which it now takes some abuse, I run a few times across the fine stone and bam back to hair popping sharp.
