First of all, I gotta say, nice blade.
Second, I love mine with maroon micarta on competition finish.
But.... I have to say I’d love it more without the fin. It looks cool and all, but I can’t for the life of me figure out what it (the fin) is good for. It’s like an appendix, hanging there on the back of the blade, getting in the way. I guess if you’re going to relegate it purely to the apocalypse that is unlikely, the back corner could be sharpened enough to cut its way out after a slash/stab. Or, if you wanted to make it more useful as a working knife, subdue the corner so you preserve the forward balance for chopping, make the corner less of a nuisance in utility tasks.
I’ll keep it, and beat it, as it has a decent balance, and fantastic fusion grip. And it is a beautiful CF blade. I just don’t particularly like the fin.
BTW, the fin on mine wasn’t sharpened. The back corner was rather acute, but it wasn’t sharp. And good luck getting the part of the fin closest to the tip sharpened. Unless you have a belt grinder, that’s gonna be a long time comin’. The fin widens out toward the tip on mine, to about a 3/16” or so flat on the spine.
Don’t get me wrong. I wouldnt want it sharpened. Heck, I don’t even want it there (which is why I ordered the bigun without the fin). And I love the knife overall. Just cold on the fin.
