Thanks for your kind words my friend! :)
And glad you like my posts, though still keep in mind: While I do post a lot, I am certainly not one of the really experienced and knowledgeable members here.

I think you might be being modest mate, ive been reading your posts and you seem to know a **** of a lot about knives and steel.
Hope you don't mind me sponging it up bro.

Thanks again! / I´ll pm you, so to not derail this thread - but it is just honest, not modest to say that I am not a steel expert at all. Just learning from all the great people here who share their knowledge.

I would like to know, too. I’ve never owned a SE knife in S30V, and would like to know how it holds up, compared to other steels in SE.

Sorry D, I missed this somehow.
I am actually loving it. Modding the serrations was brilliant. It took a little work and it was a bit of a leap of faith as I felt like I was putting years of sharpening on a new knife but since I bought it used for a good price I had less to lose.
Edge retention seems good and the cutting aggression is impressive. It also seems very easy to touch up on the sharpmaker now that the serrations are toned down. I have been carrying it almost every day for quite a while now and it hasn’t left me wanting anything else.
I hope this thread inspires others to tweak their serrations to their liking. As a plain edge fan it was key for me to get rid of almost any and all snagging which I think I did a pretty good job of.

I wish I could say more about the steel choice but I don’t have much experience with other serrated steels. It does seem to cut aggressively for a long time but that would be expected considering it is 15 dps on the serrated side giving it an inclusive angle that is probably under 20 degrees. It has been very easy to touch up on the sharpmaker.
It has been durable enough. It has survived quite a few zip ties and some accidental contact with metal unscathed. I did have the smallest microchip at the tip when cutting some thick rubber gasket material to make a custom gasket at work. I was trying to cut out small circular holes for the bolt holes and I was pressing very hard. It is hard to describe just how thick and tough this material is and I was certainly pressing the tip into the wood below and twisting the cut. The chip was very difficult to see and only a knife geek would have really even noticed. I am sure it will sharpen out quickly. I trust this knife’s durability.

I am almost done reprofiling my SE saber-ground Endura 4 to 30º on the Sharpmaker with the CBN rods. Well, 15º on the scalloped side and whatever angle the back is ground at, maybe 5º? The scallops are maybe three times as tall now and the points are wavy. I have a little more grinding to do on the inch closest to the handle to reach apex inside the scallops there. I have spent more than an hour actually stroking that CBN rod, over the course of several weeks, possibly two hours. I'm really looking forward to using the brown rods soon! I have had this Endura for years and almost never used it because I didn't like how it cut. It was paper-slicing sharp, but not a great cutter for my needs. I'm curious to see how I like it after the edge is done.
I did the same thing to my Ladybug hawkbill Salt, but it took a tiny fraction of the time. H-1 sharpens much easier than VG-10, and the angle might have been closer to start with, though the scallops gained a lot of height on that blade, too.

Thanx Darby,
It does seem to be a tough SOB. Thanx for sharing.
Hey Bill, let us know your thoughts after using it?

Yes sir, I will report back. I’ve been grinding past my bedtime because I’m so close to reaching that last bit of apex near the handle. CBN rods are doing well despite very heavy use on the corners.

The steeper secondary bevel certainly will do much better, but of course it will not change the rather obtuse primary bevel (I mean the one that starts below the upper sabre grind part of the blade) and it will not change the fact that higher up on the blade wider material will hit the shoulders that are a nature of the sabre grind.
On the other hand: On a more obtuse primary bevel: A 15 degree angle on the secondary bevel will go higher up the blade than on a more acute primary bevel. So will hit that first "shoulder" later, which should be great in things like flatter whittling or cutting stuff with not too much diameter.

I know what you mean about the inflection point at the shoulders. I will try it with shoulders intact before making any further modifications. However, I own two saber ground Delicas that I convexed by hand to eliminate the shoulders and it made a huge difference in how they cut. I prefer FFG knives, but my history with Spyderco extends back to a time before the Delica and Endura were available in FFG.Wartstein wrote: ↑Fri Feb 05, 2021 1:28 amAlso curious how it will cut for you overall when you´re done!Bill1170 wrote: ↑Thu Feb 04, 2021 11:22 pmI am almost done reprofiling my SE saber-ground Endura 4 to 30º on the Sharpmaker with the CBN rods.

went to the aquarium today. if anyone is still on the fence about serrations, the great white wants you to know that they are definitely the way to go.

That re-profile job took longer than anticipated. Today I carried my Endura 4 SE for the first time since reprofiling the serrations to 15 degrees. I took it up through the fine rods and it’ll push cut paper.
The scallops are now about 1/4” high up the primary bevel, and the teeth are very wavy. I was trimming some Jade plants that had engulfed my mailbox and sawing at them wasn’t super effective compared with my PE FFG E4, most likely due to the greater thickness at the spine and the steeper ramp of the saber grind. Then I thought, “Hmm, this’ll push cut paper. What if I chop at the jade?” So I did and it worked beautifully. Jade is very soft, similar to celery stalks. I haven’t tried the Endura in my kitchen and likely won’t. We have thinner knives much better suited to food prep.
Later I tried to cut the end off a heavy 2” diameter cardboard mailing tube. It bit in well but wedging stopped it before it got through. With great force I could have gotten through, but it didn’t feel safe to do that where I had it, and I had to get to work for a client. There was a metal pipe inside the tube.
It does great cutting plastic film, whether free or against a backing of cellulose. One great feature of SE is its ability to initiate a cut from the belly where a PE wants the tip to concentrate force. Even wavy serrations do a great job at this. Another great quality is how the scallops “trap” a free-hanging film so it doesn’t run away while being cut. The same dynamic applies in corrugated, which I haven’t tested with this knife yet.
I’m so sorry my SE Endela went missing, because it was the ideal FFG testbed. My Caribbean SE works so well with its 20-degree scallop bevel that I’m loath to mess with it, at least for now. I’ll keep carrying the SE E4 and report back as it encounters other tasks. I want to try shaving softwood.
Edited to add: Hooray!! I just found my Endela! It was wedged in the upholstery of a reclining chair along with my spare truck keys. What a relief after many weeks!

One day I’d like to get around to making a thread about natural serrations in which sharks will get a starring role!
The thread will ideally cover serrations’ entire known history from origins before the Dinosaurs, hundreds of millions of years ago in the Permian, to the modern day within our context of Spyderco knives.

VG-10 lasts a lot longer at the PE tip of an SE blade than H-1 does. My Pacific Salt frustrated me with rapid dulling of the tip area.

No doubt early man mimicked animal teeth when they first figured out flint knapping.
