Blacksmith's Whetstone
Understand how a Blacksmith's Whetstone improves weapon quality in Path of Exile 1, why item level and rarity affect efficiency, and what quality does not repair.
What happens if you use it?
Weapon quality increases toward the ordinary limit.
The weapon type and existing modifiers remain.
The weapon is worth keeping and the target makes efficient use of quality currency.
Quality cannot repair a poor base or modifier set, and efficiency varies by target.

Strengthen the weapon's foundation, not its modifier roll.
A Blacksmith's Whetstone raises a weapon's quality. Quality improves the weapon as a base object; it does not replace its random modifiers or turn an unsuitable weapon into the right weapon for a build.
Spend fewer when the source rules reward the target.
The PoE1 source directions say the whetstone has greater effect on lower-item-level, non-unique weapons and ordinarily caps quality at 20%. Check the target first, because the same quality goal can require a different number of whetstones.
Quality cannot replace poor modifiers, change the weapon type, or guarantee a meaningful character upgrade. Verify the item's level, rarity, present quality, and ordinary quality limit before spending repeatedly.
Routine use still creates a measurable market.
Weapon-quality currency is used across progression and finished equipment, but its exchange value still changes with league supply and bulk demand. The market observation describes current trade, not the power gained by a specific weapon.
