Worx 20V Mini Chainsaw vs Sharper Image Cordless Mini Chainsaw

Buy the Worx WG322 if you already own Worx 20V PowerShare batteries or need a saw for limbing and small firewood, since its 10-inch bar, auto-tension and auto-oiling suit repeated cutting. Buy the Sharper Image if you want a complete pruning kit in one box for light yard work. The Worx is the more serviceable tool; the Sharper Image is the lighter, more self-contained package. Owners of both describe them as light-duty saws, not replacements for a gas or corded saw.

• Choose the Worx 20V Mini Chainsaw if you are already in the PowerShare battery system or plan to cut limbs and small logs regularly.
• Choose the Sharper Image 1.5 lb Mini Chainsaw if you want a ready-to-use kit with battery, charger, spare chains and case for pruning and brush.
