Why would it be scrap? The witness line is there for a reason

 

I thought they were there to help with the angle not as the end of life indicator.

Recently done the Swedish Saw certs, their advice is the tooth needs 4mm left on the side plate (at its narrowest) and 2 mm on top plate (at its narrowest) to be considered safe.

 

Personally id keep using that chain

[Richard Thompson]

Plenty of life left in that chain and even if it's past the witness mark it's good for an emergency chain last ditch use chain or any dirty cuts,

Many a time I've used a chain like that to finish a job if I snap a tie strap or if I hit fence wire in a tree

[R Mac]

I'd use it, the one currently on my 501SX isn't much different and I haven't considered replacing it yet.

 

I've just bought 2 x Rototech but even then I still wouldn't throw them away while they still have life in them. To the witness marks for me, there's plenty of life if you use a file, on a grinder it might be different.

I keep them to this point in regular use, then when they start to blunt quickly keep them for disposable tasks. Cutting plastic, roots, wood with masonry or metal such as fence wire in it.

 

Yes I'm tight, but I also have a conscience about resources and have had since I was a kid. Long before all the tick boxes recycling exercises came on the scene.

 

You will probably find only those that can maintain and sharpen a chain correctly will actually still be able to use it effectively at this point of wear.

Use it or bin it? I pulled this out of our scrap bin, some of our lads consider this to be scrap.

If that were true it would have stopped cutting long before that point!

Narrower Kerf on a worn chain, faster cut speed:thumbup:

[Stephen Blair]

Bin it!

[arbaholic]

Those two teeth don't show the entire picture. If any of the other teeth are blunted back to the line then it's a finished chain if not it's got another sharpen or so left in it. I would keep it for dirty stumps, everyone's got one of those chains you know the one that sits at the bottom of the toolbox never to be used again and eventually meets its peril by way of rust.
