Once you learn maintenance it’s not bad at all. You can keep that same 1$ going for a decade with a 4$ sharpening stone. The 100$ for decades and have a much better time doing so. Plus learn to hone your knives and you will need to rarely sharpen them. Hone it once for 30 seconds before a meal and that’s it for about 4-6 months if you have a decent knife.
I have tons of stuff that’s old as hell that I keep in excellent shape by doing some very basic maintenance. A 50 year old kitchen mixer needed some new grease and that’s all it will need for 10 or so more years. Almost all the tools I own and use are 40-50 years old, it just takes a little ingenuity and love to keep them going. Though much of it is my pride refusing to let me throw away a gold tool, even if it needs a little work.
