Cold water's not your problem, that mix was bad before you ever touched it.

Turning off image lazy loading did the trick for my old laptop, pages just pop now.

Honestly, I check the weld every single time I swap blades now. Took a chunk out of my boot once when a weld let go, and that was enough for me to spend the 10 seconds running my thumb along the seam before I even tension it. It's not overkill, man, not when your hand's in the path.
