Ok, I just had to resurrect this thread to give an update on my Fortis. I found myself home early today and it was time to tackle the boxes that had built up in the garage since last summer. We're talking about a veritable s-ton of boxes here. The boxes in question housed a bed, a couch, a piano, and numerous kitchen appliances. Basically all of the wedding gifts we got last summer, well their boxes had accumulated and now they had to go. Knife fiend's paradise if ever there was one:
So I decided to grab my Fortis, which I hadn't used much at all since sharpening it on the Wicked Edge (which is documented earlier in this thread). And I also grabbed what is my usual go-to for lots of dirty/hard cutting, my S110V Spyderco Manix. I figured I'd cut for a while with the Fortis to see how it performed and probably need to switch to the Manix once the Fortis's edge started to degrade a bit and the thicker blade started to give too much drag for effective cardboard cutting. Well let me tell you, that is not how things went:
The Fortis did it all. Never once did I detect the cutting performance degrading throughout the process. It would drag a bit when tape residue built up on the blade, but a little WD40 and it was a laser beam again. I cut down everything in the garage using nothing else. I was frankly astounded by the performance of the M390. When I was done it wasn't hair-shaving sharp to be sure, but it still cut phone book paper. A few minutes of easy stropping on a Flexx Strop and we were back to this:
In the end it was just as discernibly sharp as when I began. Not changes to the lockup, action, etc. This knife can perform, folks. I'm pretty set on grabbing a G10 one to add to the collection after this. I can't help it. Best bang for your buck out there!
