Кузнечество
Crafting any tool or piece of armor will grant it a quality value. This quality value is equal to your generic Smithing quality stat PLUS your Smithing quality stat for the material the item is made out of.
Each item has a "neutral" quality as well, it's not very important to know how it works but in a nutshell it defines the quality tooltip displayed on the item. This neutral quality is also used to define when an item's stats should be equal to vanilla stats.

The quality tooltip is determined based on how much the item's quality differs from its neutral quality. If a wooden pickaxe has 90 quality for example, it'll have +40 compared to its neutral quality. The table below shows which tooltip it will be given.
-500
Terrible
-60
Shoddy
-30
Decent
0
Good
30
Great
60
Flawless
90
Masterful
120
Fabled
150
Peerless
The 90-quality wooden pickaxe would be "Great", because +40 is more than 30 but less than 60. For an item to be considered "Peerless" it needs to be at least 150 quality above its neutral quality, meaning that a Peerless wooden pickaxe is far less impressive than a Peerless netherite pickaxe as the wooden pickaxe only needs 200 quality whereas a netherite pickaxe needs 320.
How to gain Smithing quality
Leveling up grants you 1.5
Smithing quality to your items, up to 150
at level 100.
The Smithing skill tree (see /skills) has perks each granting +50
quality to a specific material.
The final perk of the Smithing skill tree grants you another +50
to everything.
So leveling to 100 alone grants you a total of 250
Smithing quality, but there are ways to push past this.
You can reset Smithing and enter NewGame+, granting you a permanent +50
quality per loop, for a total of +100
should you choose to do this twice.
Leveling Woodcutting eventually grants you access to Crystal Apples, which give you +50
Smithing quality (among other things) for 30 seconds when eaten.
If EnchantsSquared happens to be installed, it adds the "Forgemaster" enchantment which (at max level 3) grants another +50
Smithing quality.
That means you can accumulate a total of 450
Smithing quality assuming the default configuration. The plugin was balanced around 300 being the assumed max, so you can get some pretty overpowered stuff doing this.
The impact of Smithing quality on items
The item's neutral quality as mentioned above is an indicator when your crafted items do not receive buffs or debuffs for their quality. The only exception to this is netherite, which will have the same scaling as diamond equipment.
