Does anyone here uses professional/commercial equipment for home use?
For those things you're calling "utensils," and I call "small tools," yes almost entirely.
The core of my pots and pans is still Calphalon -- the first anodic Calphalon (not non-stick) -- which were commercial before they became popular and the usual suspects started selling them. They're fine, and if Calphalon was still making them I'd still be buying them if I could get them cheap enough. But they were priced through the roof before Calphalon discontinued them. SOL on that.
If something needs replacing, it's more likely than not the replacement will come from a restaurant supply.
My primary restaurant supply, "Action," does a lot of business in remaindered china and service ware. For things beyond our basic china (we have three complete sets) it -- along with thrift stores -- is a source. As one person in our relationship has an infinite capacity for dish sets, tureens, ginger jars, cream and sugar sets, cazuelas, divided plates, decorative bottles, etc., it's more about keeping things out than finding new.
