I do buy some cheap to preserve the good stuff- my EDC folder for example is a WM Ozark Trail $1 knife. I abuse it at work. I carry a good SAK which is rarely used, but more trustworthy.

Daily granola bars vs the better made for my PSK or evac ruck.

Constant wear at low cost is a trade-off. Yeah, I trust the cheap stuff to sustain me until I can access my better equipment.
