This was on diy Network's "Cool Tools". This seems irresponsible to me for them to portray and show chainsaw use like this.
Did this guy just use this chain saw with the blade like that?
I didn't get a video of this one, but this guy didn't actually do the cut, but they made it look like he did and they made it look like he did it with the blade like that.
I'm not sure this is an appropriate way to straighten your saw bar.
