Spyderco HAP40 Thread

Exactly. I'm a little reluctant to carry ZDP, and while VG-10 is a solid all-around performer, I like something with more edge retention. Plus that thin composite blade.... mmmm.

This tread just caused me to place on order for a HAP40 Stretch. It remains to be seen if it can kick the Byrd Cara Cara FRN out of my back pocket? But we're going to give it a chance.
I have Cara Cara, and if the Stretch is similar in fit & finish of Endura or better, you'd like it! It' should be a much better knife and a much better steel. I haven't tried reprofiling it to my usual face shaving sharpness (I did the SuperBlue), but I'd say even if 8Cr gets super sharp & capable, SB is more & from what I read (Lance & others), HAP40 even better.
Thanks! So it is more 'scratch' proof than 420J...?
I've owned a couple ZDP knives, and I usually carry a ZDP Dragonfly when I'm in town. That being said, I've previously used a ZDP knife for pruning tomato plants, and 40 minutes of work resulted in significant corrosion damage. As I do a lot of work related to the production or sale of vegetables (tomatoes included), I'm somewhat hesitant to regularly carry a ZDP blade.

Get a patina onto your ZDP, it'll protect it. It's just a darkened grey haze.
I have somewhat documented my attempts to get ZDP-189 to corrode and pit, with little luck when TRYING to get it to. I think some of the blades are hit or miss on heat treat and depending one how much carbide is exposed.
But, after a vinegar soaking, I have cut tomatoes, dozens of various citrus fruits, etc, etc, and left over night without washing. No pitting nor corrosion as a result. Don't be afraid of it.

Received my Endura a couple of weeks ago so here's a shot of the pair. Still super impressed with this steel and looking to get a kitchen knife or two in HAP40 now.
Well, I've been agonizing over what HAP40 to try to obtain, and, combined with the alarming realization that I've never actually owned either an Endura or a Delica
eek made me vulnerable. This picture pushed me over the edge, so in spite of over paying, inbound are one of each (figure I can recoup a lot of the cost if I don't love them). Fingers crossed for pretty lamination lines...I put an edge on my HAP 40 Delica yesterday.
Long story short, that knife is now face shaving sharp. It's the sliceist (Note--that should be a word here) Spyderco I've ever used. I wound up doing a re-profile and took it all the way down to 5000 microns + green compound strop. Since it was a re-profile, I used my EdgePro, but that steel takes a great edge and a beautiful polish. I swear it would have been fine with 10 passes on each side of the blade, but I went a little more than that.
I'm a big Super Blue fan, but I'm all on board with the HAP 40. It's killed stuff. After putting that edge on--and it will dry shave your arm hair without tugging.--I cut stuff up for about 20 minutes. I did cardboard, paper, plastic milk jugs. It had gotten to the point I was taking stuff out the recycle bin to use to test the blade. After a lengthy session of slicing and dicing, that blade was still plenty sharp, and after about 5 passes on each side of the strop--black and green--it was back to sick sharp. As noted before, it's definitely the thinnest Delica I have, and that helps make it the super slicer that it is.
When I got the knife, it was not up to Spyderco's usual standards. It was not very sharp, and the primary bevel was off--by about 2 degrees--on the non presentation (Spyder) side. I was originally going to keep it tucked away, but that never seems to work out. This one was meant to be used for certain, as the lamination lines are also way off. So yesterday I finally had the time to really put a nice edge on it, and put it through its paces.
I was all over the Super Blue, as I have a couple of Japanese clad kitchen knives, and had a very good idea of what to expect. The new Delica was my first time with HAP40--and now I'm looking for a kitchen knife in it-LOL
It's amazing steel, and it's equally amazing that a company that is as successful as Spyderco is taking the time to do this. Doing Sprints has got to be a lot of work for the $$$ involved, especially given the numbers produced. I don't know when I would have ever had the chance to try out HAP40 if not for the sprint runs.

@ElBee what angle did you go with?
Since Spyderco usually puts such good secondary bevels on their blades, sometimes even <15 dps, I just find myself touching up with the Sharpmaker at 20 degrees which gives an almost nonexistent microbevel, and feel like it'd take a couple years or more at the rate I touch up before I have to grind the shoulders back.

The grind on my Delica is pretty even, at least to my eye. I've been using it a lot at work, (I'm in the camera/lighting dept, in video and TV) cutting 10' seamless paper and lighting gels and it's fun to see it outperform the mat knives some of my colleagues prefer for these tasks. So far I've been able to maintain the original sharpness with just a few passes every other day or so on a leather strop (black and white compound).
dcfis: It's just way different from S110V. HAP40 will quickly take a very sharp edge and hold it quite well. Touch ups are easy. It would be difficult to get S110V that sharp and touching up the edge would take quite a bit more effort--it will stay sharp longer though. HAP40 is not a stainless steel, S110V is. I like them both!

Oh yeah. It may not hold its working edge as long, but it's fine edge holding is fantastic and it's very easy to sharpen. The more and more steels I try out, the more I find I prefer tool and high speed tool steels over stainless steels. I'd take the same knife in CRUWEAR, M4, HAP40, Super Blue, and K390 over S110V unless corrosion resistance is a major concern.

In what application? They are really apples and oranges. I prefer HAP40 for my EDC needs if that is what you are asking.

For a fillet knife or something where I use a very coarse edge and want maximum working edge retention and corrosion resistance I would choose s110v. For edc and general use I MUCH prefer hap40. No contest...not even close.

Looks like you guys are thinking the same thing I am about HAP40! Despite that it's a boutique steel we rarely see in folding knives (perhaps never seen before in a production folder?), it seems to me that it's a perfect EDC steel. Easily gets scary sharp and holds it! It's not as rust prone as some other steels of its kind and with that SUS410 lamination, there's really not much for us to worry about. Seriously considering a Stretch now, though I definitely intend to get a Dragonfly. Those of you who know me know that I'm not a "steel snob" and am quite happy with AUS8 and VG-10, but wow do these blades in HAP40 have me excited!

Some argue what makes a great knife steel is the balance between how will a steel sharpens and holds an edge. Hap40
Some don't care about ease of Sharpening and what the wear resistance jacked up to its highest potential.
These people either don't sharpen there own knives or have the right abrasives and skill to get the job done. S110v
Which one are you?

I think this is a pretty fair assessment. ^
I have been very happy with my Stretch Hap40 and find it to be the best combo of sharpness and ease of sharpening that I own (compared to S30v, ZDP189, 1095). I have been slicing things left and right with the stretch and its a joy to use.
At first I foolishly cut an apple on my granite countertop with only a styrafoam plate between the apple and the granite ...not a good idea with a sharp blade that goes right through the plate. It gave a flattened edge on a portion where it hit that I could see in the light. Maybe 10 passes on a medium sharpmaker rod and it was back to that sticky sharp edge that grabs your finger when you slide your finger across.
Pretty neat stuff.
