Hello, I have a question for the group:
Does anyone know of other knifemakers that cnc/ mill the blades for their knives, similar to the norseman, and shows that gradual step pattern?

Is there any impact on performance with milled blades? I have only ever seen these in pictures - do those extra shoulders hinder cutting performance?

I’ve got a The_Iron_Joe The_Iron_Joe Academic friction folder with a milled blade, I don’t notice cutting performance suffering from the milling. Joe does it right, can’t speak on the others.

Thank you :) it looks really good and I guess it does speak to the ability of the maker, I'd be curious to try some of these milled blades, but I guess most, if not all of them, come with a pretty steep pricetag.

I came across american blade works that does that, also as mentioned north arms had that design, looking for like something more production than custom, not as expensive as a norseman retail lol

I have my blades milled with the same method. the performance is great and it actually can reduce binding when chopping and friction when cutting. It's more expensive to do this method than on edge milling but it gives really great results.

The old US made Kershaw Zing and Groove both were milled like that on the blade grind, except vertical grind lines instead of horizontal along the length of the blade. They're old school designs though that have been discontinued for a long time.

Do you mean milled so you still see the tool paths, or bevels that are milled as opposed to ground? For instance, I know Half Face Blades mills their bevels, but they go back over them with tight tool paths to remove the milling lines. I suspect a lot of high end Chinese makers do something similar, especially for complicated compound bevels. But the extra machining time is much less expensive for them to do in China than it is for HFB to do in San Diego. I think the "corrugated bevel" on my Busse Hell Razor II looks pretty cool, but from a machining standpoint it isn't too impressive.

Ya I mean so you can visually see the tool paths on the blade
