Funny you should ask. I just got back into the house after spending a few hours doing yard work, involving frequent applications of Core straight, serrated and saw blades on all manner of vegetation. Same thing yesterday, plus Core screwdriver for assembling a bird feeding station. My multi-tools are in use every single day, weekends not excepted. I'm an old guy. This has been going on since I was 12 years old. Seems like the right thing to do.
