One thing you see in every vise review is measuring clamping force. As long as it's pinchy enough to hold your work, this isn't all that relevant. But I guess people love them numbers.
The Fireball Tool guy (Jason, I think?) made several videos explaining the engineering and design tradeoffs behind many of the features of his Hardtail Vise. This one explains exactly why the handle is shorter than the internet basement dwellers expected, and even why it's designed to break or bend before you can damage the rest of the vise:
For example, one thing you noticed in the PF review was that different vises had different thread pitches on the lead screws; this is a deliberate design choice as you trade clamping force for speed and convenience. So the test where he applied a certain amount of torque and measured clamping force was not telling you which one was "better"; it was telling you what design decisions were made. And the handles that bent were not evidence of lower-quality; they were a design choice to prevent overloading.
As always with so many tool reviews, over-torquing to failure was completely pointless. Made for good video, I suppose, for people who like seeing tools destroyed, but the only real function of destructive testing is to gather up more eyeballs so you can pay for more stuff to destroy.
On the plus side, showing the amount of slop in the vises was good info; that makes a difference in daily use. And I do like how he doesn't just dismiss the value options -- the HF vise is kinda crude, but it's inexpensive and perfectly useful and usable for someone on a budget. He's done the same for a lot of budget tools out there when the value is there for a usable tool, even if it's not the super-expensive option.
As someone mentioned earlier, I would have liked to see where the new Doyle vise from HF stacks up. Maybe it wasn't easily available when he made this video.
