Nothing to critique here, very well done. As far as the shop, also hard to critique but I would change:
Like Sam said, claw hammer gotta go.
You need sturdier table for the rivet press. Make it big enough for the hardness tester too while you are at it. Kneeling down is hard when you get old, trust me.
Your hand sanding support. That clamped board is just not cutting it compared to the level of thought you've put in the rest of the shop/tools/jigs.
Of course I am just suggesting these for fun cause I am sure they are all on your shop upgrade ToDo list already. Which, if you are like me, is about a mile long and not getting any shorter.
Oh and good looking knife of course. Thanks for sharing Aaron.
PS: I keep hearing the voice of the robot from "Lost in Space" when I see that Danger sign.
