CPM 20CV — rolling

[3D Anvil]

To add to the @Chronovore quote, i think the difference is the speed of the factory belts. Im sure they take it under account but generaly, all sharpening devices we use at home are working in slower speds and this gives us some advantage. It is common practice among knife enthusiasts to re sharpen factory edges, usually right after purchase. I like to leave it for a while, it gives me chance to see if the factory angle suits my needs and to figure it out should l put steeper angle or not.

To be fair, the factory is also removing a lot more material than we typically do. They're starting out with no edge bevel at all.

Thanks for your input. I too always keep the factory edge on for a while, and use the knife with the edge that the manufacturer intended.

I don't think there's anything wrong with the Hogue Deka or 20CV--both are fine products and I've already used my Deka several times today. Nevertheless, when a high quality made in the USA knife dulls so easily from what was (maybe) the lightest of taps on a granite countertop (through cardboard), I think it's fair to ask questions about the steel, heat treat, etc.

On granite
Yes, it's fair

There have been some exceptions, but most factory edges I've used didn't last as long as the edges I've put on later. To be fair, I typically lowered the edge angle and the factory edges were all over the place in terms of quality and edge angle. I've recently adopted a different approach to replacing the factory edges, but I think the results would have been the same.
