I don't think I am being harsh - he, like a lot of highly intelligent Americans does what highly intelligent Americans do: think hard, work it out and go ahead. You guys are the best at this and in the absence of an apprenticeship system, are pretty much constrained to learn skills this way. 11/10 to you. It's how I have done it here in the UK! I had no-one to teatime how to make ukulele and under the mentorship of BobGleason somehow made it to the start line pretty fast. Thanks Bob!
It is clear however, that he has had absolutely no training an arboriculture and knows very little timber technology. That aside, my observation was accurate, namely, "How for the purposes of greater viewer likes and hits should I now proceed? I know; I've partially wrecked my blade. I can call that a 'fail'. Videos with there concept of 'fail' always do well. I'll simply make another cut, don't care how poor or difficult it might be and that will totally trash the blade and they can see, I'm not afraid to trash my blades! and then I can have an 'epic fail and more hits. And more hits means more revenue..."
Judgemental - no. Just pointing out how cynical and perhaps dumb that second cut was and how ill-informed he is in that he cannot recognise the iconic shape of a piece of barbed wire - the stuff epic Western movies, American culture if you will was made of!
In the UK a spade is a spade. Matt Cremona is a YouTube vlogger and part of a growing community that is seeking patronage just so you can watch therm do stuff like this. My daughter, 5' tall and mother of 5 kids went out and bought a 42"chainsaw and an Alaskan mill and converted a felled spruce on her property. Her husband's a Canadian dentist... They just watched a few YouTUbe videos and went ahead. So I'm a fan of gungho, haveago woodwork. Just not silly gungho, haveago woodwork!
