I have never seen a rivet fail; that does not mean that it does not happen. I have seen some cutters and tie straps break at the rivet hole; they are usually heavily worn at the bottom, and likely subjected to some shock loading or run when dull.
One of the reasons I clean chains before sharpening is to be able to inspect them better for wear, cracks, etc.
Some guys will grind down their rivet heads to make 'race' chains, which weakens the connection. And I have seen several poorly set rivets, when someone tries to reuse them, or apparently peens them with a rock, instead of a spinner.
I prefer to spin loops down (make them shorter, using just the original chain material) than spin them up (making them longer by adding new material). If I add new material, it is in at least as good of shape as the existing loop, then I grind the cutters back to fit. If the tie straps are really worn on either, I prefer not to mess with it.
If the chain breaks on the bottom of the bar, just before it reaches the drive sprocket, most of the remaining chain will get 'pushed' off the top and fall to the ground (only a few, remaining drive links will ever touch the rotating drive sprocket). The remaining chain may have some momentum as it leaves the bar.
If the chain breaks on the top of the bar, just after it leaves the drive sprocket, most of the remaining chain can get whipped around the bar until the drive links lose contact with the sprocket. Remember that the links are traveling around the bar about 20 times/second.
So, a chain catcher is a good idea. So is wearing gloves, chaps, and safety glasses. It is also the reason for the wide, flat, hand guard under the rear handle of modern saws (not just to place your food for starting).

I like both full chisel and semi-chisel. When sharp, they both work. Not worth arguing over in my book. Simple as that. Time to cut wood before it really gets cold and cold is not that far away.

Ya, that Carlton stuff was terrible!!!! I thought it was my filing, so I ran it on the grinder and I dropped the rakers to .030 and it still wouldnt cut for a hill of beans.
Glad to hear I’m not alone on thinking this way.

We just have them in little coffee creamer tins. Nithing fancy likevwgat you have. Just a marker label... 375", .325", 404, etc.
They aren't too hard to sort out.
I’d like to get one of those Oregon’s measuring tools for chain. I got a big bucket of 1/2 used crap has to be sorted through
You can sort most by visual and the number/letter stamped in the drive link
Most dealers sell them. I have bought them for less than $1 in quantity, and seen them for over $7 other places.
Granberg makes one too, as does STIHL. Check eBay.
Helpful when you have some odd size, a non-standard brand, or just can't get the brain to fire.
I keep one on a nail near where I sort chain.

I carry one of these in my wallet in case I come across some chains at a garage sale or flea market.
I wonder what's different about it. I can't compare anything at the moment I'm running on dregs chain wise there all at the end.
I have carlton chisel on my 4000 and it seems to cut fine I'll buy that again
Well that's three of us.
Referring to Philbert's post #22, I sorted through all of my chain parts some while back and put them all in this small parts organizer. The bins off to the side contain some additional odd ball old McCulloch parts.
I am currently preparing a breaker & spinner set to mount on this bench (in the new shop) but rather than mounting it permanently and losing the bench space/access I will mount it to a board that can easily be fastened down when needed or stored conveniently out of the way.
In keeping with the theme of this thread, the bin that contain cutters frequently have chisel and semi-chisel intermixed.
Kevin - I you have the cutters properly sharpened and the depth gauges set, semi-chisel will self feed just fine. For many years the only chains I used were (old) Carlton semi-chisel, I did buy a roll of Carlton .325 / .058 recently but had not had the opportunity to try it yet.

Philbert gave me one of these and I’ve used it many times.
A lot of guys carry something in their wallets in the hope that they get lucky.

That’s what I said.
Me lucky charms
More spinner/ breaker stuff here:

Now we can get back to semi-chisel versus chisel chain.

Sure. What oil do you use for each chain type?
Well I was looking on stihls website they had some semi chisel “rapid micro” or something like that. Anyhow I phone the stihl dealer back and I get the guy who is the owner I believe, guy knows his **** anyway. Says yeah we have some. I say well I asked for semi chisel the other day and your guy said you had none. He says they call it round tooth oh brother so he’s making me a loop lol
so he’s making me a loop lolSTIHL calls semi-chisel 'RM' for Rapid Micro, and full-chisel 'RS' for Rapid Super.
Oregon has 'semi-chisel', 'micro-chisel', and 'chamfer-chisel' (all versions of semi-chisel chain), plus full chisel chain.
Husqvarna? Carlton? Others?
Trade names vs. shapes.
