That lifetime perspective is really on point. I recently bought some used barber supplies from a guy who's mom is in the styling business. There's been a shift for them to go cordless/battery powered for convenience and I wound up buying some trimmers and clippers from him for a fraction of the cost. The lifetime these tools were designed at far exceeds the lifetime of my usage with my family and stuff; they'll go the distance for sure. I've since come to learn that this little market does appear to have pretty serviceable parts as you can see with a lot of exploded diagrams they put out https://www.proproductsandmore.com/images/andis_sl2_trimmer....
I'm trying to remember what the lifetime quote to me was, something like these clippers were meant to cut 20 heads a day, day after day for some number of years. I realized at the rate I was going they'd be heirlooms to pass on to my son and stuff.
