Where's Wartstein on this one? He's been loving BD1N on the manix 2 lw lately.
Well, Wartstein has to sleep from time to time (you posted this at 3:59 am where I live)
- but here I am!
...... But, the BD1N steel really impressed me!
...... I found BD1N to hold up pretty well for a couple days before needing a quick touch up.
Well, actually I was thinking about starting a BD1N thread myself, and I would actually have called it something like "The BD1N miracle": I am also really impressed by that steel! And it is reassuring that you (Rick) feel the same, cause my own experience with steels is certainly not as extended and especially much less "systematic" than yours.
Now, why "miracle"?:
According to Larrins recent article (viewtopic.php?f=2&t=86503) BD1N has less edge retention than VG10. And of course I absolutely believe in his results!! (And as far as I recall BD1N has less carbide volume than VG10)
But still my Manix 2 LW in BD1N just keeps an edge a LOT longer than I would have expected. And as far as I can tell clearly longer than my VG10 knives and certainly longer than the Manix in "just" BD1 (without "N") I had (while it is still very easy and quick to touch up)
Now, why is that? I really don´t know.
I just can assume that perhaps Spyderco runs BD1N harder than VG10 (in Larrins test BD1N was "softer" than VG10 (BD1N close to 61 RC while VG10 was close to 62)
Or it is the due to the edge geometry of my particular Manix (or the Manix generally)? (Quote from another great Larrin article: " And I would argue that the single most important factor for knife performance is the edge geometry rather than the steel selection or heat treatment. The edge geometry greatly controls the cutting ability and edge retention of the knife..." https://knifesteelnerds.com/2020/07/13/
Anyway: I really, really like this steel... and I think it would be great for serrated edges!! Actually, in kitchen knives Spyderco uses it already with teeth and I just can advocate for a Manix 2 LW SE
here once more...
