Over the weekend, I took it upon myself to do a little early Spring cleaning as I came across a bunch of large postal service boxes and other large cardboard boxes from the holidays. Lots of cardboard plus sharp Military in pocket equals lots of fun for a knife nut. I had previously sharpened this knife to a 1000 grit, 18 dps edge using the Wicked Edge (WEPS) which results in a laser edge that performs wave cuts in phone book paper effortlessly.

There were at least 4 or 5 large postal service boxes which has not the thickest cardboard but still heavy duty. And there were another 5 or so large boxes with much thicker and nastier cardboard that was much harder to get through. I broke each of these down into the smallest pieces possible to make disposal easier and for the hell of it. So there was a lot of cutting going on for a couple hours.

After I finished the first half of turning boxes into confetti, I got out some phone book paper and I was impressed that it was still slicing like before I started. After all the boxes were finished, I did some more phone book paper slicing and there were no snags or hitches. If you're used to really sharp edges, you know that "quietness" you get with a laser edge and phone book paper so in the end, it was maybe just a touch louder but you know what I mean. I have to say I was really impressed.

For the touch-up, I placed the knife back into my recorded settings for the WEPS and put on the 1000 grit stones. Now my stones have over 150 knives on them, and they are like glass, virtually no metal removal with these so I was skeptical. Well about 10 or so light passes on each side and I felt that beautiful, sticky sharpness on the edge. Now I was even more impressed. I think I ended up making 20 light passes per side, and now the blade is back to doing S-cuts with ease. (Swig of beer for the WEPS too)

In conclusion, with the many choices of steels on the market today, S30V is one that we've frankly gotten bored with. I'd have to say Spyderco has perfected this steel, and it may be the best bang for your buck steel out there. Great edge retention for all-purpose use with easy touch-up without breaking the bank. So swig of beer for Spyderco's S30V and to the Military, one of the finest cutting tools on the market.
 
S30v is arguably my favorite steel in the entire Spyderco lineup. Great balance of edge retention and ease of sharpening. Yeah, I've got some of the "super steels" but in my use the difference in edge retention is negligable if even notable. I think folks just get bored with yesterday's flavor but s30v with spydercos ht is a premium steel all day long in my book!
 
My favorite steel as well. Four of my six Spyderco knives are S30v. They are also the four I use the most.
 
S30v is in my top 2 of stainless steels. Have two 2 blades fabricated with it one being my spyderco native. But then again I'm not a high end steel junkie so I have limited experience with the more exotic stuff, really not a need to upgrade, s30v and a few other mid grades work well for me and are proven.
 
I want to love s30v! But I'm finding my dlc pm2 is chipping, I'm not an knife expert or a expert sharpener I sharpen it 30 degrees inclusive on a sharpmaker, I don't use it hard , but sometimes cut things that are abrasive. And to try and work out the chips on the diamond rods takes hours. What am I doing wrong?

I want to test out my PM2 in the same manner I did my Military. The PM2 is sharpened at 30 degrees inclusive like yours, stropped to 0.5u so this would kind of test a highly polished edge plus a more acute edge than my Military. I've used this PM2 to whittle some cedar I have laying around, and last time after close to an hour of whittling I could feel a couple tiny rolls in the edge which stropped right out on the WEPS. So I have not used that one super hard really, but no chipping so far. I'm sure I can round up a bunch of cardboard soon to see what happens.
 
it's nice to hear from folks that use their knives, reminding us all that S30V is a pretty incredible material. now that it seems like every manufacturer is using S30V on their more mainstream knives, it seems like there's a lot of people wishing for more exotic steel on all their knives ... but at the end of the day, S30V is an incredibly balanced steel in terms of what you look for in a knife that you will use every day - corrosion resistance, edge holding, sharpen-ability, etc.
 
I'm wondering if the process to put on the dlc coating (heat) causes the steel to become more susceptible to chipping? Any one else use a dlc coated s30v?
 
If so I wouldve stated that in the 5 paragraphs of the OP.

I've had VG-10 chip before doing heavy cardboard work.

I'm not saying this is necessarily the case here but here it goes anyway;
Factory edges are put on knives with belt sanders and this method can generate excessive heat at the very apex of the edge. Its not uncommon for a brand new knife to need to be sharpened once if not multiple times to get to "fresh" steel that had not been damaged by the factory sharpening. If this were the case on your knife and the sharpmaker is your only method of sharpening it could take quite a few times resharpening before the damaged steel is removed and your chipping problem goes away. Depending on how deep into this knife nutty world you've become, you may want to consider investing in an edge pro or wicked edge to have the ability to more quickly reprofile you edges.
Also consider putting a 40° micro bevel on the knife in question.
