Wait, your place stays a steady temp even when the power goes out for real? That's wild, I didn't think ICF was that good at holding temperature without any HVAC running. I always figured it helped with insulation but not like full on thermal battery mode lol. How long did it stay comfortable for you when the power was out - like hours or days? I'm honestly kind of shocked that's even possible with just concrete and foam.

Wait, are you serious about having nuked clover for years? @the_charlie I've got a patch of crabgrass I've been poisoning forever and I'm starting to wonder the same thing.

I had a similar thing happen to me a few years back. A guy I was working with on a big job in Baltimore pointed out the same marking on my Kleins. I looked at it and just laughed. I have been stripping wire for over a decade and never noticed that little groove. But I still use the side that fits anyway. The wire goes in, it strips clean, and I move on. I just don't see how it makes a real difference on solid wire as long as the insulation comes off without nicking the copper. It works fine for me, so I am not switching.

Funny how we always assume it's complicated when the fix is usually simple.

Seems like a lot of effort just to bind some paper.
