This review is a long time in coming but I finally got the time to post up all of my thoughts on these awesome blades.

Right off the bat that I want to send a very heartfelt thank you to sodak for letting me borrow the two beauties. His generosity is amazing. Thanks man.

On to the knives!

sodak sent me two Caly 3s. One standard, and one reground. Speaking to the overall design of the knife, Spyderco really hit it out of the park with this knife. It's a great design. Size, weight, blade shape, handle shape, materials, workmanship, pretty much everything about the knife is outstanding. Compliments to Sal for this one. It's one of the best folders I've ever had the pleasure of using and I will most definitely be picking up a Carbon FIber/ZDP version in the future. I can't speak to the out of box sharpness as I'm sure sodak has resharpened it before but I will say this, unmodified, the Caly 3 is one of the best cutters I've ever used. A truly great design overall in my eyes.

As I mentioned, the stock Caly 3 was one of the best cutters I've ever used but the Krein reground Caly, well, that was the most effortless knife I've ever had the pleasure of using. Everything I cut using it was easily done. I used it to take down a few cardboard boxes one night at work and it out cut the boxcutter I had with me. In fact, it wasn't even close. The performance was so good that I didn't even think about touching up the edge until a week or so before I sent them back. I think I did about 5 or 6 passes on the Sharpmaker at 15 degrees. After that, I didn't really notice much difference so either I didn't do it right or the Krein Caly really didn't lose any performance level. I feel that it didn't lose anything.

I'll admit, I didn't push either knife too hard seeing as how they are not mine. I did use them though and both, especially the Krein Caly, were noticeable improvements over most of my other knives. I've emailed Tom about his customs but haven't heard back from him. I'll probably call him soon to see if that will work better. I know he's very busy but I'm very interested in one of his knives. I'd also like for him to do some of his regrinding magic on one of the new Swicks I recently picked up.

Overall, if you want a knife that will cut, cut, and CUT, the Calypso 3 is a great choice. If you then want to take that knife to the next level, send it off to Tom Krein and have him regrind it for you. You'll have a knife that glides through just about everything it cuts like it's not there.
 
Glad you liked them! Once you go thin, it's hard to go back... Welcome to the dark side! :D
 
I've been thinking very hard about trying to see if I could get Tom to do my user Caly and after reading this it's sounding that much more tempting.
 
Yeah I think I'm am pretty hooked on thinner edges for the most part. I've even going to see about thinning the edges some on a couple of my Busses myself. Cliff Stamp had success doing that in some of his reviews and they still stayed crazy tough.

StigmataDiaboli,

I'd say go for it. It'll cut like there's no tomorrow.

You won't be disappointed. It's even better than the VG10 model, which is very good. The edge holding is easily triple. If you want to thin one out, the ZDP is the one to thin.

Keep in mind, the thinner you go, the stronger the steel needs to be in order to support the edge. A lot of dulling is caused by the edge rolling, which a stronger steel will prevent, hence the longer edge holding. While different steels have different properties, strength is directly proportional to hardness within reasonable limits. If the VG10 model is at 58HRC (I don't know, that's just a guess), and the ZDP model is at 64 HRC (another guess), the higher hardness will allow you to go thinner, all other things being equal. It will resist deformation much longer than steels that aren't as hard. Hopefully, the steel will also have the necessary strength and other properties as well to avoid chipping, etc. ZDP has those properties. It's one of a handful of steels that really, really benefits from thinning. Some others I've used that also do well thin are CPM 10V and CPM M4.

So, while the VG10 really does well, the ZDP is in a whole 'nuther category. It's like going from High School Football to the NFL. No joke.

If you are thinking about thinning a Busse, consider a Boney Active Duty (BAD). They were hardened to 62 HRC, and would probably give you the most bang for the buck. But if you thin out something else, I'd be very interested in the results! ;)

Agreed. It's shoved most other knives out of my edc rotation. Spyderco hit a grand slam with this knife!
 
Yeah that's one of the reasons I'm interested in a custom from Tom. I don't know what the specific hardness of the the Busses I have is so if the option presented itself, I'd really like a 3V blade from Tom in the 60+ area. Get the best of both worlds on that one.

And truthfully, I wouldn't thin the Busses too much. The ones I use the most, my Scotch Dispenser and my BATACs actually came very sharp and have stayed that way through all the use I've put them through. It's addicting though! Once you start using the seeing the advantages of the thinner edges, (my Swicks came pretty thin too) you want to see just how far you can go.

I really can't wait to get my hands on the ZDP too. The Caly 3 is going to be got but I may hold out a bit and get one of the Mules first. Truth be told, when I get paid next I may pick up a Mule in S90V too. So many great choices right now.
