Overview
This cordless CAN-WFJ-28MM saw runs on a 21 volt battery at up to 3500 RPM, with a high carbon steel blade and a body measuring 7.1 by 3.5 by 15 inches. Shoppers bought more than 50 units in the past month.
The 28mm in the model name lines up with a compact chainsaw or mini saw class of tool, built for small branch cutting and pruning rather than felling or milling. High carbon steel blades hold an edge well for wood but need more care around rust than stainless options.
- 21 volt battery power
- 3500 RPM motor speed
- 7.1 x 3.5 x 15 inch body
- High carbon steel blade
Who it's for
Good for someone pruning branches, trimming a garden or doing light yard cleanup who wants a cordless tool small enough to run one handed. Not built for felling trees or cutting large lumber, where a full sized chainsaw is the right tool.

Performance notes
At 3500 RPM the motor spins fast for a battery tool this size, which suits quick cuts through smaller branches rather than sustained heavy sawing. The 21 volt battery and compact 15 inch length keep the tool light for one handed use, though runtime will depend on branch diameter and how often the trigger is used.
