I made a few comments about the DT blades when I first got my CF DT small 21, and now I've been carrying it every day for 3 weeks. Let me start off by saying that, when you're comparing blades/steels available from a company like CRK, it's all preference; you can't really go wrong. When I got my first Sebenza, only a few short months ago, I was in love with it immediately. I had no complaints with S35VN and couldn't have been happier with my purchase. I sold that Sebenza to try something different, not because I didn't like it. Right, on to the DT blades.

Although I haven't had this knife very long, I've gotten a good feel for the steel and would like to share my thoughts. Devin Thomas' stainless damascus really is something else. Prior to owning this blade, I've always thought of modern damascus as decorative, rather than highly functional. This blade has proven me wrong. The reason I bought this particular knife was to own a "higher end" Sebenza that I don't carry every day. That didn't really pan out, and for good reasons.

Edge retention: My first Sebenza came to me ridiculously dull, brand new. That is uncommon for CRK but it is what it is. The DT blade was the exact opposite. It was extremely sharp right out of the box, as one should expect. Not only did it come super sharp, it has held up remarkably. I am not one of those "hard use" guys because I really don't know what "hard use" you're going to encounter on a day to day basis unless you're like...Rambo...or something. Having said that, I use the knife like a tool, not some piece of jewelry that needs to be babied and kept locked away from the dangers of dust and air lol. The knife comes out daily, whether I'm in the yard making sure everything is neat, or out camping taking care of setup and other chores. I've used it to cut harsh stuff too, like wire mesh, zip ties, etc. It took 3 weeks to notice any kind of dulling and even at that point, I could've easily gone another 3 weeks without stropping this knife and it'd stay working sharp at absolute worst. It could still shave a little yesterday before I sharpened it. In my experience, the edge retention on the DT has been far superior to S35VN.

Edge quality: S35VN is extremely easy to sharpen, and it takes a great edge. It's not rocket science getting an S35VN blade up to silly sharp but, the DT blade is on another level. The DT blade takes on a ridiculously fine edge with almost no effort at all. BF member Unit advised that I back off on the pressure while sharpening and I did just that and was amazed at the resulting edge. This doesn't mean I think that the S35VN blades currently offered have lower edge quality, they are just different. In my opinion, if you sharpen them both with a fine edge in mind, the DT will be much finer and it will be easier to get there.

Durability of the finish: This was my biggest concern. A plain stonewashed/polished blade that takes on wear won't look too bad. Usually you just get some fine scratching that doesn't stand out too bad against a normal blade. What about the DT blades? If use I it, and it takes on wear, will it look like a coated blade with hideous high contrast scratches and scuffs? These are the questions I asked myself, and I again have been pleasantly surprised. No matter what I've cut, the finish on the damascus blade has stayed beautiful. I was pretty worried when I was cutting wire mesh recently. I thought "this is it, today is the day my blade gets it's first mark". I was wrong, it is still flawless. The durability on the finish isn't going to be as good as the standard blades, but it's pretty damn good. Definitely not something you need to worry about.

Maintenance: Nothing special here. Keep it oiled, wipe it down when you're done with it, and enjoy it. This stuff is TOUGH!

I hope someone who is considering purchasing a CRK with DT blade finds this useful. Thanks again to Unit for encouraging me to pick up this knife, and giving me info on it prior to my purchase. Below are some pictures of the newly refined edge, and some anodizing work I did to, yet again, make this knife "my own". If I ever get tired of the new anodizing, it is all reversible, and I've manage to find the voltage needed to color match CRK blue on my particular power supply, with the methods I personally use.

Thanks for reading and making me feel welcome around here, BF CRK-sub members. Unit, Kidcongo, Tmack, biggerjon, I have enjoyed the little bit of back and forth conversation we have shared regarding these knives. You guys are alright!

note: I am not using the clip below on any of my knives. This is a "decayed" finish with some pitting that was done on request for someone else. Just showing it because, why not?

Looks good!

I don't even oil mine. The finish is a bit tougher than I expected. I take it in the field for core drilling, groundwater sampling, and aquifer testing. It gets exposed to all sorts of crud and lots and lots of sweat...it's quite corrosion resistant.

It's way too nice not to use;)

Nice pictures and write up. I'm reminded of the interference pattern on that blade, it's really hypnotizing.
 
Funny I just received the exact knife just days ago. I have been using damascus for years so I know how well it performs, but i'm glad to hear this one is no different. I also started with a stonewash blade recently and then went after the one we both have. Similar story. =)

I don't really think stainless damascus needs to be oiled. Heck, I don't oil my carbon damascus EDC and its fine. Just always wipe it after use.

BTW, getting a good edge- or just stropping a bit IS rocket science to me. I have never really done it right. Any pointers? What exactly do you use for it? Maybe I just don't have the right materials.
 
Thanks Harris.......I am hoping my next CRK purchase will be a damascus, so your info is really helpful. Just gotta save up for a while and resist the temptation to buy others. What did you use to do the pitting on that pocket clip? Really cool!
 
Nice read here..I really was curious as to how the damascus would stack up against other steels. Quite honestly, most of the reasons that I have stayed away, you addressed..The only one that still concerns me is the corrosion; Over the years, I have learned to wipe down any precision tools that I have because most are some form of tool steel..if I don't..They WILL rust and corrode..usually with my fingerprints all over them. Out of all the machinsts I work with..I am the only one with this curse.
I am one step closer to getting one in the future. Will probably have to wait until after the 1st of the year for various reasons :)

Thanks for the insights!

Good to know, I will probably continue to oil it out of habit because the blade is a porous pattern welded steel but now I know that I don't need to. Thanks.

As far as edges go, I use a spyderco sharpmaker and freehand sharpen my blades. Aside from the sharpmaker, I've never owned a guided system before (i.e. Wicked Edge, Edge Pro, etc.). The sharpmaker is great because it makes getting a perfect 20 degree per side edge a snap. You just have to make sure your hand isn't shifting angle, and using the flats from the medium stones to the super fine stones (sold separate from the SM) you will get a solid, sharp, and durable edge. If you like, you can then strop the edge using some fine polishing compound and refine your edge further. This is probably the easiest way to get a very sharp but close to factory edge.

In regards to particular edge in this thread, what I mentioned above would've worked fine but I really wanted to get a ghastly sharp edge out of this steel so, I started on my whetstones. Using some honing oil, I maintained an angle of just about 19 degrees per side on a soft (fine) Arkansas whetstone (roughly 700 grit). Next I stropped using 1000 grit sandpaper taped to my stropping block. From there I used the fine side of my stropping block (the green side in picture) to clean up the edge. The stropping block I use is just a two sided coarse/fine compound loaded strop. Same angle as on the stones, roughly 19 dps. After this I stropped on 2000 grit paper, then finally on a 8000 grit micro mesh cloth. If you maintain a slow and steady stroke, being careful to lift/move the knife so that the entire edge gets hit equally, and at the same angle, the technique is left up to pressure. On the DT blades, very little pressure is needed. The weight of the blade is plenty!

Thanks Cody. It's hard having to wait out a big purchase. Good luck to you. For the pitting, I used Comet with chlorine mixed into water, and ran a 12v current through it. In this case, the chlorine in the cleaner was used to bite into the Ti, leaving the pits you see. When you run a current through the solution the chlorine starts to basically cook. I might have the science of the chlorine thing misunderstood but it did what it was supposed to. Personally, although it looks kind of cool, I wouldn't want it for myself but, the guy who bought it from me seems excited.

Glad you found it useful! I really wouldn't sweat the corrosion (no pun intended). I've left the knife dirty with steak juice, citrus, or sweat for nights at a time. Other than a wipe down, the knife wasn't washed and it has had no effect. If it can handle that, it should be fine so long as you wash/wipe it dry when you're done with it.

Thanks, I'm very happy with how the etched false damascus style anodizing turned out on the insert. Im still in awe at how great of an edge this blade takes on, it really is something else.

I am glad that you are enjoying the knife and making it your own. It looks awesome!

I have used both the stainless and carbon DT blades. It was easy to see the corrosive nature of the two almost immediately. There is really no need to treat the DT any differently that a regular stainless blade. I will say that a freshly oiled damascus blade is too beautiful not to do though. :)

Thats exactly what my worries were also when looking at the DT blades. I still don't have one. I would really like the large 21 CF basket weave pattern. Maybe I'll get one in a few months also... and Zeta thank you very much for the awesome writeup it is excellent!
 
Would you recommend the Ultra fine Stone when using the Sharpmaker on the Damascus blade? I haven't sharpened mine yet, just thinking of touching up the edge some. Also what is that you placed under the screw after removing the pocket clip? Some nice looking Sebenzas there.

Definitely use the ultra fine stones. The clip insert is a CRK accessory I bought and then did a pseudo "timascus" anodizing job on.

Those are some nice blades Zeta!

Thanks! That anodized large 21 is the one I got off of you! I wore it in some more before anodizing it.

Others, I'm glad you guys are finding my rambling useful!

Thanks for sharing - great pixs too.
That anodized inlay is way cool.
Now I nearly decided for the raindrop pattern, but since I saw you pictures, the ladder pattern is back in the race.
Though choices....

Thanks! Ladder Damascus is very attractive but so are the basket weave and raindrop patterns. It's a tough choice to make, no doubt. Each pattern has it's own "personality" to it.
 
Just called in to get a DT blade for my Large 21 and there is apparently a 9 month back order :eek:

Noooooo!
 
Thanks a lot for sharing your experience ! You've added another perspective when looking at my damascus Sebenza.

Wow James, that's a beautiful collection of Damascus Sebenzas!

Guys, I'd go ahead and oil your DT blades even if you think you don't need to. Although the SS Damascus is resistant to corrosion, it is not impervious.

I noticed today after using mine that the blade has accumulated a few very very tiny brown spots, near the base where the scales meet the blade. I used some very fine polish and an artist's triangular cotton swab to remove them as much as possible but there are two marks that have been reduced greatly but are most likely permanent.

I can only assume that this happened due to not drying off the blade well enough after cleaning, then storing the knife in it's slip pouch too long. The leather must've trapped the moisture in.

In any case, the marks are very hard to find unless you're looking and this knife is a user. It's got a few bright spots already and I have cut some pretty tough stuff with it so I'm not worried :D
