^hopefully you keep them sharp.
To me, a proper knife (razor sharp) is essential. The fit is also important for precision prep work.
I've had relatives with crappy knives.......and on holidays sometimes I'd be asked to prepare something.
I have memories of hacking through meats and veggies with dull blades........cursing. Once I was asked to make a meat and cheese tray (pepperoni, salami, etc) using dull paring knives..........took an hour when it should have taken minutes.
I have purchased good knives for several relatives.
