I just replaced my windshield wipers last night and it was a nightmare. The wipers I got are supposed to be universal, which means the little plastic bit that connects to the wiper arms has a bunch of little sub parts that you’re supposed to remove based on what wiper arm connection your car uses. Well, considering I’m not well versed in modern wiper arm connection standards, and I’m also stubborn and don’t think you should need to dig out your car manual just to change your fucking wipers, coupled with the fact that the instructions that came with the wipers are just 6 wordless diagrams vaguely showing you what bits to remove based on which esoteric wiper style your car uses, I struggled with those sons of bitches for like 20 minutes in below freezing weather.
Does victorinox offer sharpening services? Some knife manufacturers have programs where you can either send your knife in or take it in to a store and have it professionally sharpened.
If your blade is losing its edge quickly, it probably needs to have a new edge put on it with an actual sharpening, v rather than just the touch up it gets from a honing rod.
