Quick answer

The Gtech Grass Edge Trimmer GT50 is the clearest match if you want a cordless grass trimmer that uses replaceable plastic blades and converts for edging. Consider the STIHL FSA 30 if you want interchangeable PolyCut blade and AutoCut line heads, or Yard Force LT G30 if a wider 30cm nylon-line cut matters.

Best for blade trimming and lawn edging

Gtech GT50 Grass Edge Trimmer

Gtech specifies an 18V lithium-ion battery and a 23cm blade cutting width.
The swivelling head switches between trimming and edging; the stated runtime is up to 30 minutes.
The product page says the kit includes 20 replaceable blades and a battery and charger.

Drawback: The manufacturer states a four-hour charging time, and the plastic blades are a distinct consumable from nylon line.

Best for interchangeable blade or line heads

STIHL FSA 30 Cordless Grass Trimmer

STIHL supplies a PolyCut 3-2 head with two replaceable polymer blades.
An AutoCut 3-2 line head is also listed as a compatible alternative.
The head can be angled for lawn-edge work, according to STIHL.

Drawback: The FSA 30 is also offered tool-only, so battery and charger inclusion depends on the variant.

The product listing gives a 40V 2.5Ah battery and up to 30 minutes' runtime.

Drawback: This is a line-fed design, so it does not meet a preference for replaceable blade consumables.
