Right now I'm very dubious between the two knives posted by IG (the second one is real crap!) and the gutting bottle opener by graymaker.
I actually like the horrible knife by CL
I have no ugly knife to post. Right now I've made just one knife, and it's not ugly (I won't say it's good, though)
But I've seen a couple of ugly knives, and want to introduce a couple of production knives to you, just to add some representatives of the "industrial" cathegory

one of which makes all those posted (but the gutting bottle opener and the dry wall screw ones) seem like finely crafted masterpieces.
I don't have pictures, unfortunately. It was sent to the knife magazine I write for for evaluation. It's not a custom made knife: it's actually mass produced and it gets sold!
It was so disgusting that we refused publishing it. The knife was kept as an example of how a knife shouldn't be done.
It's real, real crap...
And then ther's this one, by none else but Puma Knives, which once used to make damn good industrial knives.
Now they are down peddling this crap...
Note: you can't see it in the picture, but the other side is flat, the blade being chisel ground...
It's the ugliest production knife I've ever seen.
