Hi there, I think you will be pleased with the grinds on the 3mm stock. There has been uniformly positive feedback, aside from Shabazz, who never bothered to cut anything with it. They cut like the dickens. All my Pena and Romano customs have 3mm stock and I’ve never heard anyone complain about those. Just watch Logan’s and Stassa’s videos where they effortlessly slice up food and materials. Regarding torx: I am recommmending people do not take them apart. Because they are hard to put back together due to the spring. But they can be taken apart. There is no good reason to fully disassemble it though, in my opinion. The covers, however, are very easily removed and reinstalled without hassle. I have a video on my website and youtube where I do a complete disassembly and reassembly for people who prefer to do so. I had to use my bench vise to do it. Spun pins were never an option, with this type of manufacturing, from this manufacturer. And part of the “modern” traditional aspect of these knives is the construction method, aka threaded barrels, screws, CNC, WireEDM.
