So last week while we were out doing our annual wood cutting trip my son comes up to me with a distressed look on his face. He says:"I accidentally hit the dirt dad". I thought back to a time when I was his age saying the exact same thing to my dad. With the same look on my face, When I did that my dad got very angry & threw the chainsaw in the back of the truck and "said... great!....Now we're done for the day! " I never forgot how terrible I felt, and at the time never knew how to sharpen the chain.I was so very sorry to have ruined the day.
Fast forward 30 years now my son has done the same thing. I looked him in the eye and told him, it's no big deal it happens to the best of us. I told him also that I was proud of him for stopping and bringing it to my attention. I explained that continuing to cut would not only wear him out but possibly damage the saw as well, and not get any work done to boot. Then I showed him how to slap on another fresh chain and we were back in business not even three minutes later. Then I showed him how to avoid hitting the dirt in the future by cutting 3/4 of the way through rolling the log and then finishing with an up cut, I think my dad would've been proud at that teachable moment.

That was a good bit to remove!@Khntr85 keeps asking for photos. Here is a damaged full chisel chain, where I had to take the cutters back pretty far to get back to clean metal on the top and side plates:

Tecomec makes most of the Oregon grinders - they are also sold under the 'Jolly' name. These are not clones.. . . from what little I can find it doesn’t look like there’s much difference between the Jolly and the Oregon 620 . . .

However, in some cases, there are different features on the Oregon models such as: built-in lights; 'down angle' grinding; compensation for wheel wear / centering, etc. Hard to tell without seeing them side-by-side. Not sure about any differences between the hydraulic models.

They are probably identical. Maybe call Bailey's (during the day when their main staff are there, NOT at night when only the order takers answer the phone), or write them, and ask, since they sell both?

Double check with @Philbert but I believe the tecomec are made basics just like Oregon’s....I know a lot of guys like them....Man, for someone in my shoes where im not sharpening to make a living and just want to learn on a bench grinder, that seems like a great price.
As I understand it, Tecomec makes most of Oregon's grinders, but the Oregon grinders may have different features (built-in light, double clamping vise, grinding wheel centering adjustment, etc.) on different models, along with different warranties and support. But the quality of the grinders should be identical, compared to the clone grinders.Double check with @Philbert but I believe the tecomec are made basics just like Oregon’s....
