So, I used scissors for years, have now had a couple of trimmers. Last one is now too blunt to use. Is it possible to buy one with a few replacements parts so it lasts a bit longer? They seem to exist for men's shavers...
It just seems so wasteful to replace the whole thing, from an environmental POV... I refuse to go full hippy and have a giant bush though. 
Just wondering if anyone knows if such a product exists, or failing that what you'd recommend for one that lasts longer? (Last one was Phillips bikini genie.)
