This is how I D&D
Dungeons & Dragons 3rd edition had a lot of cool features.
One of them being masterwork items.
Masterwork items simulated well-crafted weapons, armour, and items found in the world, which gave you minor bonuses when used.
The most popular of these were masterwork weapons.
Skills in 5th edition Dungeons & Dragons are pretty limiting.
You get your allotted number of skills at first level, and they stay pretty static throughout the game; only really getting better when you level up and your proficiency bonus (slowly) increases.
I find this a little odd, given that in the real world a person can get better at a skill, and I don’t think it’s a great leap to think fantasy characters could as well.
