If you're reading this review, it's because you realize that the Deka is a great knife that deserves far better scales than the ones it came with.
You're in the right place.
I had initially replaced the stock originals with a micarta pair from another manufacturer, but I still wasn't happy with them. In part, the micarta was too light and made the knife feel unsubstantial. The micarta scales had the same shape as the originals, too, which I realized wasn't a good fit for my larger hands - between the finger notch and the slope of the butt, I just wasn't able to find a comfortable secure grip. Finally, from an aesthetic standpoint, the added material for that notch gave the knife an unpleasant visual bulk. A clean blade paired with a clunky handle.
The Skinny Goats are a night and day improvement.
I love the heft of the aluminum. It's got a presence, but not enough to seem heavy. The sharktooth texture provides exceptional grip. But the absolute best thing about the Skinny Goats is that they eliminate the finger notch. The knife feels better in the hand and just looks better without that ridge.
The Skinny Goats make the Deka what it was meant to be. They're more reliable to handle, more pleasant to use, and by far more attractive to look at. These are what the Deka should have come with in the first place.
Buy 'em.
