    Using K390 vs. S110V is night and day. S110V chipped consistently for me, K390 has not chipped. I run it at 15 DPS and it is beautiful.

    I saw the dragonfly at 100 and thought what a deal. The K390 Urban was great but I want a lock.

    wow, this seems to be really popular, I'm surprized k390 is holding up as well as reported...
    thing is, if you have cpm-m4, it feels like it stays sharp forever (imho)
    I honestly don't think I need higher edge retention

    so you guys go 2 months between sharpening? 4 months? half year?... honestly curious

    K390 is an awesome cutlery steel for folders and makes perfect sense to me to be the next 'common super steel' IMHO...its edge stability is just stellar. Now also might be an optimal time to launch a full K390 line as well, as it seems like diamonds have become much more common in the sharpening arsenals of many knife owners. When Spyderco launched their ZDP-189, I didn't own anything very optimal to sharpen it, and it seemed like many knife enthusiasts did not at that point in time.
  4. I thought Pete (Cedric & Ada on youtube) made a good point in his review of the K390 Ladybug: when you've got a smaller blade, and therefore less edge length to spread wear over, the benefit of really high edge retention is magnified. On something like the Dragonfly (2.25" blade) or Ladybug (1.94"), your ability to shift to a different part of the blade when the sweet spot dulls is pretty limited. As I mentioned earlier, the only production steel these models are offered in that has notable edge retention is ZDP-189, which is much less tough than K390 (and was actually out-performed by K390 in edge retention in Larrin's testing). If you look at why the ZDP-189 variant of the Dragonfly is popular, K390 offers a performance upgrade for a negligible price difference ($98 vs $94.50 on BHQ).

    How it compares to M4 isn't particularly relevant to these knives, since none of the Spyderco K390 production knives have been offered in variants with anything similar to M4. Even accounting for limited production variants, S90V is the only other steel that has comparable performance to K390 (and that was a 600 knife dealer exclusive Delica; none of the others have anything other than the ZDP versions for high edge retention steels).

    The review:

    A K390 uncoated blade will rust easily and for an EDC it's not convenient so I will not buy a K390 knife if it's not DLC.
    I hope Spyderco will offer the DLC option for interested buyers.

    I hope k390 (or equivalent) makes it into the Golden and Taichung models. Given the recent success of M4 and REX-45, I think demand would be high.

    The elephant in the room is that k390 is only made in Austria (as far as I am aware). If subject to tarriffs, it raises the already substantial cost of shipping. It’s probably more likely that analogues from Crucible (CPM 10V) or Carpenter (Micro-melt A11) get used in Golden and perhaps Taichung.

    It would be cool if Sal (or another knife manufacturer) could convince either Crucible or Carpenter to to modify A11 or 10V by adding Niobium and Cobalt to improve hardness and toughness. If SPY27 ends up being a success, hopefully we will see more of this.

    I have a much carried and used Urban Light Weight K390 that has yet to show a single spot of rust, yet I live near the sea where the air is salty and humid. So, while not a “stainless” steel, it resists rust pretty well.

    Reviving an older thread but I just ordered a K390 Endela. For me it is two birds with one stone as I want to test out both the Endela as well as the K390 steel.

    I like this news. The endura is one of my top 2 favorite knives. 10 years from now, it's the only knife I expect have a chance to still be on the market.

    Has anyone gotten their hands on a K390 Police? I am waiting for Knifecenter to fulfill my pre-order for one and am anxious to know what others think about it.

    My Endela K390 is on it's way. I used to be scared of knives that rusted, but with very little care they will patina (rust like layer) rather than rust as one would think. That patina keeps it from further rusting and reduces care and maintenance.

    The Police was one of the first K390 models Spyderco offered, going back a few years. I recall people complaining about lock rock, but otherwise a great knife.

    I love my PM2 and am currently loving my Endura in K390.
