Extended Dual Grit Edge Testing | ANDE Rope Series

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!

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

[@homeslicesharpening]

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!

hi! im new to the channel, super interesting stuff! In your oppinion what steels are most suitable for the dual grit edge? i have a lot of different knives in good steels, but my only magnacut knife is a serrated spyderco (and therefore not so relevant for this method). Curious if you have found other steels as suited for this method? for example elmax, m390, cts xhp, s30v, s35vn? etc if you already have a video on this topic that would also be a suitable answer ;)

Hello! I think that dual grit can have benefits for a large variety of steels. I think steels which benefit most are those with good carbide separation (think like 14C28N, MagnaCut, CruWear, CPM M4, 3V, 4V etc...) Those are some great options you mention. If I were you I'd start with a diamond plate (one side) and a fine water stone (other side of edge), cut up some old jeans and strop with them laid flat with some Mother's Mag & Aluminum Polish. I'd try XHP and Elmax first, of the steels you mentioned - but the other's should be possible to dial in as well.

Did you catch this? kzbin.info/www/bejne/Z6i2mIGEqJd8ibc that would be a great tutorial to start with.

@@homeslicesharpening Thanks! Makes sense, i will try the elmax first! I have a fixed angle guided system with diamond stones and lapping films, should be interesting to see if waterstones are the key or you can do it with fine diamond stones/lapping film also.
