I love SG2. I carry an SG2 blur or JYD SG2 all the time--wonderful stuff!

Anthony, The SG2 knives you used were the JYD2, or the Blur? If it was the JYD 2 the probable cause of the chipping is the extreme thinness of the blade, cutting edge and the fairly high RC number. That's a real bad combo on something as hard and dense as Hog bones. I don't doubt a thicker, softer 1095 knife chipped less.
The Blur was thin for a blur, but not scalpel thin like the Ti JYD2. Out of the box my JYD 2 would whittle hairs , probably even nose hairs
.
Not something I personally would chose for butchering hogs, though cleaning bass should be fine if I wanted my nice slick Ti framelock to smell fishy. I wonder if metamucil would get the fish smell off?

Yeah, I have to agree that if a TI/SG2 JYD II was used to strip down wild boar you used the wrong knife for the job. The Ti JYD II has the thinnest grind of any knife I own. It's not made to chop at bone. It's not a chopper, it's not a boning knife, it's not a skinning knife. Why would you use it as such? If you want a knife to do all those things then you buy a proper blade. First off, I would lean towards a fixed blade. Secondly, I would lean towards a steel that had a lower Rockwell Hardness like 1090 or A2.
There are different knives for different jobs. Something as thin and hard as the SG2 blade on the JYD II is definitely not suited for the tasks that you put before it. There is no wonder you had a much easier time with the carbon steel blade because that steel is produced to be used like that. SG2 in such a thin stock was never meant to be used to cut through bone. If you had a Fallkniven fixed blade using the SG2 it would have worked alot better.
SG2 is not garbage steel. Quite the contrary. It is a great steel that can get laser sharp and stay that way for quite some time if it's used in the manner for which it was produced.

I don't have either of those knives so I don't know how delicate they are. But I have strictly used folders for years to skin, quarter, and debone deer, hogs, and gators and never had a problem using a folder. I have a few friends who mainly use folders as well just because they are so easy to carry into the woods. I have used carbon blade case slipjoints to ZDP and M4 Benchmades and Spydercos. I haven't had a problem yet and don't see why other knives shouldn't be able to do some of the same things unless they are just super thin. Even then if they are sharpened at a steeper angle they shouldn't get too messed up.

...and I haven't seen a lot of complaints/problems on either of the 2 knives on topic other than sunnyd's, so I'm unsure there are issues. On the contrary, I've had a ton of compliments with SG2, and feedback for additional knives that incorporate the steel.
From ZDP to S30V, every steel discussed on this forum has had issues (some catastrophic) by specific users in their real world travels. So just because you personally haven't experienced any problems with specific steels, and apparently don't feel you should, doesn't mean others haven't or won't.

That is exactly what I was saying. Just because one person doesn't have any problems doesn't mean the next might not have something bad happen. I'm not saying the steel is bad, I have never even seen the stuff. But a pocket knife can be used for those tasks and shouldn't have serious issues with it either.

What is wrong with his spelling, grammar, or punctuation? Other than you not liking what he had to say and grasping at nothing to try and be an ass?

SG2 like any steel has it's strengths and weaknesses.
On occasion, I believe the user either doesn't know, or has expectations that exceed the knife, or in this case, the steel.
I believe SG2 to be a really solid preforming steel in certain applications, but was nervous about utilizing SG2 in a pocket knife. It's strengths would excel with cutting and slicing, but rugged use could show its fragile side. We ground the blades to be quite thin with it's geometry [specifically the JYD II), and for most that used the blades, SG2 was/is exceeding with performance. Prying, bone strikes, batoning, are not going to bring pretty results with this steel.
Again, one has to come to an understanding of the tool in your hand, and the job you have in front of you. Just because it's a knife (even a high dollar piece), doesn't mean you shouldn't proceed with caution.
I guarantee you if you used the 1725SG2 in this manner, it would fail.

On a side note, I'll keep telling myself that thinner is better...I learned that on this very forum.
I love SG2 for its wicked sharp edge. Running my finder lightly across the edge of my first JYDII produced a sound like running your finger around the rim of a crystal water glass or plucking a violin string.
I purchased a couple of JYDII blems, too. One was disappointing in that the SG2 edge near the tip all but disappeared into the surrounding steel cladding. The second blem had ample SG2 at the edge but the line separating the two steels was uneven. I suspect that's why they were rejected by Kershaw's excellent quality control. But the part that does the work on both was still incredibly sharp. I'm guessing that part of the problem Kershaw had with SG2 steel was maintaining the uniformity of the amount of SG2 steel that comprised the edge. Thomas?
I also have Fallkniven's U2 folder with SG2. It, too, is a cutting demon, and exists as an option for those who want SG2's benefits in the smallest, lightest package.
I would expect these thin edges to work best in cutting or slicing tasks where bones or hard objects are not expected. Both my JYDII's and the U2 are carried when their anticipated use is limited to those actions. Would I buy another Kershaw in SG2?
At least one of every model.
God bless,
Hugh

Looks like we have a second guy putting words and assumptions in the mouths of others.

Here we go with the insults again. Did you not learn your lesson the last time you were banned?

Just wanted to comment that I've used much good steel over the years in many different folders and sheath knives--fixed blades. Most all knives made for outdoor use can be used(even if not specifically designed) for field dressing and light butchering of game animals. In my recent experience the two Junk Yard Dogs that were brought out to the site performed extremely poorly when in use for this specific chore. In addition, they did not resharpen to expectations and made generally lousy knives in my opinion as well as the the opinions of my peers at the time. Our conclusion is that for 150.+ USDer knife, one could do a helluva lot better!.
The vintage Imperial and Western fixed blades, both with 1095 steel performed flawlessly for this chore and others in camp for a fraction of the cost.. Hope this clears things up.
Thanks,
Anthony

Ignoring him may be your best recourse here with this guy.
He is well known for trolling for arguments here around the forums and stirring things up.

I think this is the second post of yours "clearing things up". Thanks for that.
Why don't you send the 2 dogs in to warranty, and we can swap them out for potentially a better fit in your gear?

Really? Could you please explain what words and assumptions I am putting in the mouths of others? If you are going to make a statement like that then surely you can back yourself up? I have not removed any content from any of my posts so please elaborate and use examples. Or maybe your just back peddling and somehow trying to save face because you made a stupid remark?
