I have to say I'm a fan of his videos. When I'm looking for YT reviews, I pretty much only prefer Nick and NutNFancy. (Say what you want about NutNFancy, but his reviews are nauseatingly thorough, and I like that).
As for Nick, I think the first time I watched one of his videos, I was looking for a video on a watch... I don't even remember which watch it was, now, but when I clicked "play" I was immediately thrown off by his strong accent. I actually thought he was joking. But as time has gone on, I tend to gravitate to his reviews, especially with knives.
And, I don't always agree with him, either. In fact, after watching his review of the CRK Inkosi (In which he was very clear that he didn't like it) I went out and bought one and have no regrets. Just because his and my preferences don't align doesn't mean that I don't still value his opinions and detail.
It also helps that he's funny.
He's prolific, that's for sure. Opinionated, that takes guts. I like his sense of humor and sometimes he makes great points, but sometimes, he completely misses the point of a knife. For example, when he reviewed the traditional Japanese friction folder and said it was of horrible build quality and not useful as EDC.
It's made and sold here as a historic EDC for Japanese peasants 100 years ago. It was always made to a low price point, and still generally is inexpensive. (and cheap!) But yet, Ol' Nick is comparing it against modern Spyderco compression locks with modern steel and costing 10X the amount? It's like it flew right over his head.
Also, he doesn't respond to most comments on his channel, which makes me think he's just cranking out videos for the ad revenue. He just blasts through the size comparisons, which is one of the more consistently useful parts of his videos.
The format is also not very good. The Good, the Bad and the Ugly? I guess 'ugly' is worse than 'bad'. But nothing is better than 'good', just so he can use the catchy movie name?
I guess the bottom line is that he's now a YouTube personality for knife nuts; a staple. I'm glad he was able to carve out his niche in our little world. Maybe his ad revenue is able to support his habit.
You're welcome to check out my channel, (Jeremy D) it's not as focused or polished as yours. Like you, it's not my full time job. I just started doing knife reviews again. I welcome your constructive criticism too.
