Did you ever notice the parallels between making coffee and shaving? Some of these might be a stretch from your perspective, but some that come came to mind are listed below. Using '=' sign to roughly mean analogous, to make this easier to read.
brewer = razor
filter = blade
coffee beans = soap
hand grinder = brush
ground coffee = lather
pre-ground coffee = canned shave cream
electric grinder = hot lather machine
instant coffee = electric razor
manual lever espresso machine = straight razor
Gillette safety razor = Melitta pour over
Bic disposable razor = k-cup
Perhaps you can expand or improve on these?
