I don’t think the combination of D2 steel and scandi grind is ideal. D2 is a brittle steel to begin with. I have broken a D2 knife in the past (not an enzo) in cold weather. When combined with a thin edge like a scandi, chipping is a guarantee. I was thinking of getting an enzo camper kit, but when I saw that it only came in D2 I changed my mind. D2 makes for a hard edge, great for slicing, but can not handle any more serious use, especially with a scandi grind. Heat treating can help to some degree, but if you want to make D2 hard enough to be a great cutter, it will be brittle. It will not be as much of a problem on a thick edge like convex or a wide secondary bevel, but on a scandi designed with a very narrow cutting edge, you will have problems unless you are careful with the blade.
I don’t think however that that is an issue just with enzo knives. Any scandi grind that is ground to a narrow enough edge will face this problem. Some bushcraft knives of the woodlore variety are fairly thick and the edge is not as narrow, so the problem is not as serious. If you look at many puukkos however, they all face that problem. I recently bought a Kellam Wolverine, and the knife came wrapped in a piece of paper explaining that the edge will be damaged if you strike with the knife or force it through any hard wood. That being said, it slices great-it’s like a razor.
I don’t know about the specific blades shown above, maybe they are particularly brittle, but I don’t think the general problem can be avoided. Select a blade for the type of work you are going to do. I love my puukko, but I will not use it as a general bush knife. For that I need something a bit more robust.
If you look at the Brisa website, there is a review of the enzo trapper when compared to an RC3. Read the very end of the review, where the author discusses the drop test for the blades.
