Steel is steel. If you use it consistently as an agricultural tool it will chip, ding, bend, etc. The user needs to get comfortable with files, grinders, etc.. Use will tell you when you can live with a ding and when it is enough of a nuisance to grind out. Axes, hoes, pulaskis, shovels, ... You can find an assortment of old tools in any old working barn. The farmer lives with them and works with them for years or decades until they are worn out.
Dedicated weapons or collector pieces are different. The owner may choose to put in extra effort to keep the item in top condition. To him the payoff for having the device always at top condition may be worth hours of effort that would not make economic sense for a farmer. Smooth, sharp, polished etc. It is not wrong to take pride in such things. However, given the practicalities of a farmer's life when you walk into his barn you will find usable, cared for, but not pristine tools.
