Audio gear, not earpods :D

When talking about BIFL, I think it is reasonably to talk about normal household use. There really is not anything BIFL for professional use unless we are talking items like crowbar.

I still think that normal user does not need to learn scissor sharpening if they just buy OK pair like made in finland series fiskars.

How long you want them to last? Fiskars plastic handles are running currently at age of 55 and still no issues.

Depends of design of scissors. If they have thick blades and self sharpening design it really isn't needed. I have 4 pairs older than 20 years, never sharpened and all cut everyday stuff without any problems, paper, fabric etc.
