This was a long time coming. Thanks to Sodak for the knives to test and patience in waiting for the review. Well, I wouldn't really call it a review; more so just some thoughts and ramblings of mine on the various knives.

Spyderco Caly 3 (w/ Krein regrind)

I have a Caly 3 of my own but always wanted to try a Krein regrind. This wouldn't be my first choice of knives to have Tom work his magic on, as it's already a relatively thin slicer in its own right. It's usually thick monsters--like SNG's and XM-18's--that benefit most from a Krein thinning. But this little guy proved me wrong.

The VG-10 edge was left almost paper thin, but as long as it isn't pushed past its capabilities, it will laser through cuts like nothin' you've likely ever experienced before. By capabilities, I'm referring to things like opening letters, packaging, thin cardboard, food (no bones or shells, though), etc. Things you'd probably be cutting anyway with an unmodified Caly 3, a knife not really meant for "hard use" tasks anyway. So the Krein regrind really just refined an already awesome slicer.

The odd blade shape left by the regrind immediately reminded me of my (now belated) small Sebenza Insingo. But when I laid them next to each other the resemblance was fleeting.

Here's a shot that tried to capture how crazy-thin the regrind is. It didn't succeed:o. However, the picture does show how very little of a secondary bevel there is (some call it primary... regardless, what I mean is the actual cutting edge). The main flat grind has been so drastically but expertly thinned out that it could still "cut" most things even with a blunt edge.

Spyderco Caly 3 (CF ZDP-189)

100_0855.jpg


Again, I have my own Caly 3, but its VG-10 blade, while adequate, sometimes leaves me lusting for more. Enter this Caly 3 on steroids. Also "upgraded" on this version is the carbon fiber scales from G10. "Upgraded" with quotation marks because I personally don't feel that CF is any better than G10, either functionally or aesthetically. This particular CF is twill, not peel ply, and very smooth [read slick]. But I don't see this as an inherent drawback on this particular model of knife because I can't see anyone using a Caly 3 so hard that grippiness is an issue. In fact, I quite like the smooth feel of it in my palm.

The gentleman who loaned me this knife said it still had its original factory edge and hadn't been touched up in any way. Now, I'm a Spydie fan to the nth degree, and their excellent edges (at least in terms of sharpness) are no small reason why. But this thing was mind blowing. It literally redefined sharpness for me (until I got a Murray Carter knife, but I digress). I have a certain test for edges called the Butt Test. It involves slicing through a cigarette filter. It sounds like an easy pass but you'd be surprised. Most new knife edges can slice through the outer paper portion but quickly seize up once they hit the inner fiberglass filter. This ZDP-189 cleanly and quickly guillotined the cig butt in half. Over and over again, without any discernable loss of sharpness.

I always hear horror stories about sharpening ZDP-189. You can't tell from the pic, as it clearly shows a deep scratch pattern from factory belts, but I somehow managed to improve the edge sharpness by stropping on leather charged with 1 micron HA diamond spray. I gotta get me some of this steel sometime soon.


Syderco Delica 4 (ZDP-189)

Even though this knife has a ZDP-189 blade too, it seemed to naturally fill a completely different role. Probably unnecessarily, I treated the Caly 3 ZDP with kid gloves, pushing it not much further than I did the Krein'd Caly 3 w/ VG-10. But the thicker edge on the Delica and its saber grind gave me enough peace of mind to make it my "work" knife for the duration of its time in my possession. It must be noted, however, that the Caly 3 (3mm) has thicker blade stock at the spine than the Delica (2.5mm).

100_0869.jpg


I didn't think twice about ripping through plastic zip ties, thick corrugated cardboard, and even some carpet I happened to be laying at the time. And it wasn't just the stronger saber grind with its thick edge that made me think of this knife as a workhorse. There's something about about the Delica/Endura line that lends itself well to beating on. Cost is certainly part of it. But the FRN handle goes a long way in classifying this knife as a beater. Yeah, it's bomb proof. But in my opinion it's also very unappealing and unpleasant to handle... so I wouldn't mind if got trashed and had to buy another knife. That's admittedly pretty twisted logic considering it wasn't my knife:D. In my defense, the owner seemed genuinely happy for me to be putting it though its paces.

100_0867.jpg


As far as touch-ups went, I found that the ZDP-189 on the Delica didn't respond as well to stropping on leather/diamonds as it did on the CF Caly 3. Maybe the Caly's thinner edge had something to do with it. Nevertheless, it sharpened up just fine on the Sharpmaker medium rods (not so much on the fine white rods, though:confused:). Stropping on the leather/diamonds after that did smooth out the scratch pattern left from the medium ceramics, making it a much smoother cutter. Nothing compared to the amazing laser-like Krein'd Caly 3, though. Here's one more parting shot, as it were...

Sodak, you, sir, are a gentleman, a scholar and an acrobat. Sincere thanks for the initial favour, and then for sitting tight through my technical foibles and general laziness.;)

Excellent review, KMN!

I can't sharpen ZDP on the fines or ultrafines on the Sharpmaker, either. That's where being mindless addicted to waterstones and lapping films pays off in spades.
 
Thanks for the great review and pictures! Yeah, Spyderco makes some fantastic knives, and ZDP is awesome.

I thought ZDP was by far the best (after 10V, of course), until Ankerson ruined my whole world with his reviews ;) :D, now I can't say that, but it's still very, very good. It takes a LONG time before I have to re-sharpen my Spyderco ZDP's.

I wish I had my Krein'd ZDP Caly Jr, but I gave it to a friend. Talk about a scary knife... As you noted, one of the very cool things about having thin bevels is that after a while, you check the knife and find it fairly dull, but it still cuts due to the geometry...

Hey, if you want a Kreined Caly Jr. ZDP with a hollow grind to a .005" edge I'll send one back with your Wilson in 10V. Merry Christmas, and I owe it to you anyway for all of the knives you've let me borrow and keep over the years, so you're stuck with it! However, I may not be able to send those knives back to you until I can pick my jaw off the floor from the staggering performance of the Wilson, which I got in the mail yesterday. It is a great pairing of amazing geometry (Krein grind type of thin) with a top notch steel with a perfect heat treat.

I agree with you about thinking ZDP would outperform most any other production steel prior to Ankerson's testing. Since Ankerson's testing came out I've been thinking about why my impression of ZDP's performance was so positive compared to the steel's actual capabilities. I tought it was right there with CPM M4 and S90V. I love CPM M4 because it gets extremely sharp real easy with excellent edge retention. S90V doesn't get as sharp for me as CPM M4 but it slices like a champ for a very long time before needing a touch up. I never thought they performed significantly better than ZDP, though, and I figured ZDP, CPM M4, and S90V were all neck and neck for the top of the production knife heap in edge retention. I now think I had that impression because of how great my Kreined ZDP knives cut paired with the fact that my most used knives in M4 and S90V are not reground. Like you said the regrinds keep on cutting due to their incredible geometry even when they are dull, so I haven't had to resharpen them that often. I seem to resharpen M4 and S90V with the same frequency as my ZDP regrinds, which isn't often, so my brain just put them in the same category for edge retention. The explanation for my view of ZDP being inflated is a Krein regrind has such a profound effect on the cutting ability of knives that it can make a steel perform way above it's level compared to a production thick knife, pushing a lesser steel to perform like a "better" steel (though I still think ZDP is a very good super steel). I always knew my Krein regrinds performed WAY better than they did prior to the regrind, I just never put it together in my head that CPM M4 and S90V actually outperform the ZDP knives I have at factory thickness since I mostly use my Krein grinds when I use ZDP. It would be great to see how much better CPM M4 and S90V would perform with the same treatment as my ZDP regrinds, but unfortunately Tom isn't doing regrinds anymore. I guess I'll just have to live with my porky factory blades from now on.

Jeez, did I miss a passaround of that amazing 10V Wilson? First Ankerson had it, now Gunmike1. Sodak, had I not made you wait 8 months for this review and soured your expectations of me, I'd be offering my first born to get my hands on it for a test drive.;)

It's a keeper, isn't it? I would love for you to shoot another hog and try it out on that. Going hunting soon? ;) The hog I processed with my Dozier hardly even dulled the blade (I couldn't tell a difference before or after), but I was careful to avoid bones. This one will do quite a few, I'd bet. Keep it for a while, I know you'll use it! I'm ashamed to say that I haven't used it very much lately.

Anyway, all the credit goes to Phil, I just got lucky and got one at the right time, when he was playing with the HT for 10V.

No problem, I'm not at all sour! It wasn't a formal passaround, just some sharing amongst friends.
