thanks for all the effort, super informative

Still enjoying these tests. Thanks man. Thumbs up crew lol

Thank you and you're welcome.

Thanks for sharing and keep up the great work.

Two of my favorites, good stuff as usual G. Thanks for all you do.

[@normal1972]

Thanks for the tests. I just ordered a k390 PM2 to go with my BBS m390 PM2. Should be a great pair.

[@stevenlachance8576]

Another excellent video and test.

[@Outpost_76]

Thank you

[@jonr1510]

I'm a little worried about my k390 dragonfly, only did 120ft fine edge. It was the second edge so I'm hoping that a 3rd sharpening will get down to some less fatigued steel. Great vid as always

[@Outpost_76]

It should, this Para 3 was pretty slow to pick up the first couple edges.

[@mikelikesknives428]

You know I am pulling for Rex45. My K390 Para3 is horrible. It feels gummy when sharpening and the burr is very hard to eliminate. It tested at 62.5 HRC. Great test as always.

[@Outpost_76]

I'd guess this one isn't much harder but it feels fine sharpening and is easy to deburr. I did it freehand after the test and it was quick and easy to do.

[@55gopi]

Are you willing to sell?

[@mikelikesknives428]

@@55gopi sell what? My Para 3 K390? I would but it’s also reground. It’s thinner behind the edge now. And the Spyderco logo is not on the blade anymore. It does cut much better now.

The colorado k390 nowhere near as good as Seki City Japan k390

[@wanderingmagoo9028]

Great video ... very interesting to see them go head to head. I got the new k390 delica. I wonder how it would go against the native 5 frn rex 45. Keep up the good work. 👍🙂

[@Outpost_76]

Much better wear resistance and better edge stability in my use. The Rex will be tougher.

[@vindice5849]

Just got a brand new k390 pm2 I'm super excited it should be here Saturday!

I should have picked one up back when they were still available. It will be a solid user.

[@steeltoez8345]

I should get Rockwell numbers for my k390 delica this weekend. I heard another tester had 66 but I can't fully trust that until more seki k390 gets tested. I'm a big fan of rex45 and when I was testing it beside my k390 pm2 I felt they performed about the same as well.

[@sneakhyperion9297]

Hopefully the endura and police test about the same

[@Outpost_76]

I'm curious to see what it comes back at. I too am hoping the Endura K390 is around 65 at least.

[@wanderingmagoo9028]

+1 on wanting to know what you find the hrc is on your Delica K390. 👍😁

[@steeltoez8345]

Idk when the video will be out but it poked 65.5 and 66 from what I've been told.

[@geraldkoth654]

Colorado K390 is not as hard as Seki K390 and it makes a huge difference in edge retention.

[@briand563]

You know what i like about Rex45 ... calling my native sexy rexy lol.. good vid G 👍

[@kjam87gxp]

Those are awesome

[@Outpost_76]

Thank you

[@dombond6515]

I would like to see these 2 ran at 300 grit diamond. Then like a 1 micron diamond film. See the results that edge finish would have on these steels. There quite different.

[@dombond6515]

@Semper Skeptical right but 1 strop only. 3 strops loaded with diamonds can really kill the aggression that comes up even from a 200 diamond stone. Ten passes per side is alot x3 is to much.

[@ryanh6378]

When sharpening some of the higher hardness steels on diamond, do you apply any more pressure if it feels like the stone is just "skating" across the surface? On harder steels, I would have assumed the more coarse grit of the 140 stone would cut it better, but it seemed like my 300 grit KME diamond stone was actually removing material faster.

[@lindboknifeandtool]

Higher grit stones remove more material with normal pressure because there is much more surface area. Applying pressure to higher grit stones will make them cut faster.

[@londiniumarmoury7037]

You want to be careful using very low grit diamond stones on steels like K390 / Maxamet / S110V etc, they can chip the edge out. You will get best results with around 400-600 grit. Hope this helps.

[@Outpost_76]

I've found that the 300 grit stone works better than the lower grit plates. I use the same pressure, not much, for any steel I'm sharpening. Harder steels that are done well even with stone skate will sharpen nicely.

[@philm.5153]

I like your videos. The narration could use improvement. Soooo slow and monotone.

[@SteveKluver]

Thank you G! This is the class of steel I love to see tested. I'm looking forward to see how your Shaman does. For the record. When they ran the batch of blades for the TreeRex. They made more than they needed to fill that Knife Center order. They set them aside, until the burnt orange scales were ready. Then they built a few of those, until they ran out of blades. I have had here, burnt orange G10 Shamans, with date codes of: LS - December 2019 FT - June 2020 GT - July 2020 HT - August 2020 So these LS date coded boxes, have blades in them from the leftover/overrun of TreeRex knives. The date printed around the pivot also shows this to be a fact. So later on, when you are possibly comparing those two runs. You'll want to know, and keep track of the box date codes.

[@Outpost_76]

That's good info, I'll keep it to check when I get some others to test. I appreciate it, thank you.

[@ASOKAEdge]

I feel the demand for both has become so high that spyderco has decided to put the hrc in a setting to run these with minimal indicant on the manufacturing end. Very interesting how these did only a hair better than my cruwear delica. It seems that Spyderco is creeping away from high performance processing like the way they used and putting more effort into the marketing aspect of their products

[@Outpost_76]

The difference in some older vs newer runs is pretty big. The same with batch to batch runs in the same steel different model. 4V Para 3 come in at 65 yet the 4V PM2 comes in at 62.5. It seems most of their steels have a wide range from run to run. Only the commonly used steels seem to be run pretty close together.

[@mattrc77]

So is there any difference between the Japan Spyderco K390 VS Colorado?

[@Outpost_76]

The Golden stuff has been 2 to 3 points softer on average than the Seki K390. The 63 rc Golden K390 cut 200 feet less than the 66rc Seki K390.

Waiting on s45vn

[@Outpost_76]

I'll get some soon

[@williamthomas5780]

Yup. I have the K390 PM2 and the Burnt REX Shaman. The Shaman is definitely harder. I don't really mind at all though. I still love K390. Even at 64. Still no slouch. I think that they should have made all of the PM2 and Paras 67 though. It's really mostly steel nerds and sharpeners that want them and if you abuse hard steel enough to break it, you lose.

[@optimuscrime608]

Rex45 is the best steel out right now 💯

[@Outpost_76]

I'm still undecided on where Rex 45 fits in for me.

[@brandonseals6732]

If u don't sharpen both the same angle and finish... u have no control in ur test... it not a comparison with a factory edge... unless I'm understanding u incorrectly

[@Outpost_76]

Unless I specify in the video every test is 15 dps at 1500 grit diamond plate finish. Then stropped on 6, 3 and 1 micron 5 passes per side. On some knives I do test the factory edge as well and the results will be in the video.

[@brandonseals6732]

My bad... thought I heard u say u were test one with factory edge... misunderstood

[@S1x_Signal_11]

How can you compare a sharpened REX 45 to a factory edge that is used on the k390? This test makes no sense

[@Outpost_76]

Both of these were sharpened many times prior to this video. Just off memory the K390 was 5 or 6 edges in when this test started.

[@bobbycarter5990]

Those look horrible.. Why ruin them

[@Outpost_76]

The K390 had the tip broken off prior to being given to me and the Rex 45 wanted a shape change. The Rex is also shorter already than normal just from use and many sharpenings.
