Ok about 30 sec's in and he's show a 5.00 pocket knife and a 8.00 "machete" so I'm already guessing what the quality of the rest of the items will be.
In my experience quality is seldom a big issue. On a fishing boat the most used knife was a $5 bait shop monstrosity with blade stamped out cheap Chinese stainless with cork handle. Its main attribute was it floated and was so cheap it was never protected so it would ride stabbed into the transom or on the shelf immediately below it. There must have been a half-dozen identical to it on board. Every few days someone would work the blade on a stone, sometimes on a piece of concrete used as a kellet, to get something like an edge. Bored on a slow day that was a favorite activity. A couple people had much better knives on their belt but 99% of the time what got used was those $5 knives because they were always right there.
The point here is to understand that survival is usually about presence and adequacy. Being there and being good enough to get by with. Our distant ancestors used chips of stone and, much later, some rather poor steel. Rarely is quality an issue in real life. I've used many knives under $20 that cut just fine and the knives keep getting better for short money.
In a real survival situation you should be overjoyed to have any knife. Given it may be all you have you're not going to throw away a $5 knife because it isn't good enough.
