Yeah, the N95's are a good step, but probably not enough. Some people weren't wearing masks at all.
Also, It didn't look like any of the saws had good safety stops, the angle-grinders were taped down, and the guy cutting the balls seemed to be really close to getting a (gloved) hand sucked into the saw.
Definitely not the worst safety, but people are definitely getting hurt at this job site. And this is what they considered good enough to show on Youtube, so probably worse than we think...
They meant puncture as in stabbing the chainmail with a pointy thing vs cutting it. They do offer some protection but it's easier to get through; more force in a smaller area
Yeah it's all about tradeoffs, really. Plate's great but it does weigh and cost more so you wouldn't see as much of it in the field – although it's not nearly as clunky as popularly portrayed because you had to be able to fight in that thing. A lot of the time throwing some mail and a gambeson on a peasant is Good Enough™ for the mass of your army
I recall a tour guide at the armory museum in Boston describing accounts of (presumably well-to-do) armor wearers showing off their suits’ mobility by doing cartwheels. Still difficult to imagine, but yeah fighting in clunky armor sounds like it could easily be more dangerous than none at all.
