For thos of you that have the Spyderco Mules in ZDP-189 and in S90V, which do you like better? Is one holding an edge longer than the other?
 
Are you aware of the manufacturing problems with the ZDP Mule blades? If you don't already own one, I would recommend that you pass on the ZDP and buy one of the others. IME the M4, 52100 and S90V are ultra-excellent. Most of the rest are really good users as well, but not in the same class as those mentioned above.

No love for the CPM-S35VN? Not even an honorable mention?

I said the others were really good, which was meant to be more than just an honorable mention...that one might actually be my favorite, but it isn't in the same category as S90V or M4, or the dark horse MT01 in 52100. The only one I could not give really high marks to is MT-05, but when you consider the price, you can't not love that one, too.

Well in that case, all is forgiven ;)
Personally, I love the S35VN steel. If only it were more widely available in the Spyderco lineup...:(
 
Phew!!! :D

It's just another case of having some super-great options like CPM-M4 and CPM S90V, but the "ordinary" choices like CPM154 (or even 154CM), ATS-34, VG-10 and S35VN and S30V are still totally excellent choices. People need to remember what it was like before all these recent super-steels became available. :)

Speaking for the Spyderco CPM-M4 Mule - I was almost done making a nice set of CF handles for it with some red liners, and my Dremel tool died :( That was the saddest moment of the weekend for me, All I needed to do was drill the holes for the Corbys and use the Acraglass. Doh!
 
S90v for sure..... I have had most of the Mule teams knives and this is my fav. The ZDP would be my least favorite.

There was a problem with the heat treat on the ZDP mules, some of them broke I think.

I may not have been paying enough attention, but it wasn't clear to me that there wasn't something else wrong with those particular knives. One thing does seem to be true: ZDP-189 is a more finicky steel to get good results with than S90V.

Thanks. Note the text in Taz's post about the ZDP-189 MT-04 Mules that I've made bold red below:

We regret that we will not be able to ship any additional MT04P, ZDP-189 Mules. Our research indicates that the problem goes beyond the heat treat. We are unable to re-temper the knives as we had originally thought. They are not repairable and we will not be shipping any additional pieces. We’ve done extensive testing on both the folders and the fixed blades with ZDP-189 and found that the problem is only in the fixed blades and that the makeup was different.

If you have an MT04P without any issues we recommend that you keep your knife. If you have encountered issues (such as breaking, cracking, etc.) please contact our Warranty & Repair department. Since we cannot replace the knife, we will issue you a credit for the original MSRP of $79.95.

The Mule Team is a project based upon the desire to learn more about the steel and its performance. This scenario, although not planned, has certainly provided some valuable information into one of our industry’s most exotic steels.

We appreciate your continued support of the Mule Team project and your understanding regarding this challenge.

Thanx much!

That's what I've heard, so I've relegated mine to office duty. It still holds an edge forever, and for cutting envelopes and things like that, I'll probably not need to sharpen it before I die... :D
