Extended Dual Grit Edge Testing | ANDE Rope Series

Do dual grit edges bend and chip more easily than traditional edges? Can they be deburred to levels where they are durable enough for heavier work EDC use? What if the edges are too worn in my normal tests, or would bend over if pushed a bit harder?
These questions have propelled me to do additional analysis on the durability of a knife edge sharpened with the dual grit method.
Also check out my tutorials on dual grit sharpening.
What's a dual grit edge, you may ask?
Think: high performance aggressive knife edge!!! This method for versatile razor sharp knives is fast, easy, and leads to edge retention increases of up to 50% in some tasks! Watch my tutorials to quickly learn innovative hand sharpening techniques with whetstone, diamond plate, & honing strop.
The dual grit method is a specific method for sharpening one side of the edge coarse and the other fine - an updated tutorial is below:

A great reminder that a good, properly deburred edge, is a good edge! Anybody could take any of of these, and enjoy.

Yeah, I was surprised by how similar the impact testing came back!

The stability of these modern knife steels is amazing. We can assure ourselves the knife business is still very competitive. This likely drives innovation in knife steel production technology that is not likely to be shared. These innovations are likely improving knife edge retention without significantly increasing the cost of production. I have recently noticed advertised HRC levels increase significantly in knives made with traditional European knife steels. These HRC ratings are significantly above samples of theses steels a few years ago. The knife makers have changed something in the steel production or optimization process.

Yeah - I think that's true! Also, it's becoming more common knowledge that steels which are that tough can tolerate higher hardness levels, so consumer demand for better hardening is growing I think!

Interesting video. I’m happy to see you post something that could be seen as “unflattering” to your dual-grit edge. In part because of that I’ve decided to try it out for the first time on a Herder Windmill carbon steel paring knife using sandstone for the coarse grit and finer grit natural stones for the fine side. Looking forward to the results!

That's awesome! Sorry for the delay, I am back in Washington helping my father in law after he lost a finger in a farming accident! I hope your dual grit adventures yield good results!
