My scale is not accurate. And the CT had some steel removed when I convexed it. Let's just say the knives are close in weight. I think the SOD is just a bit heavier than the CT. In actual use, there is no practical difference between the knives. The CT has better edge holding, but the SR77 is easier to resharpen, so that's a wash. I like the looks of the SOD a bit better. I can't imagine anyone who likes the Camp Tramp not liking the SOD.
