Last spring, I decided it was time to give up my chain saw. I was tired of the hassles involved with keeping it in good working order and all of the steps for safe use. I was relieved to let it go, but a little sad. Then I saw an ad for a tiny 4” chain saw. It’s a little bigger than my hand, weights about 5 pounds with the battery installed, and can cut branches and trunks up to about 6”. I had to have one.
I love that little chain saw. As soon as it arrived, I put it to use. Its rechargeable battery works for several hours, and mine came with 2 batteries. I run out of energy long before the chain saw does. I’ve been working on a major project clearing trashy trees from my back yard and replacing them with nicer understory trees and shrubs. My little chain saw has been handy in chopping down the trees and in chopping them into pieces that fit into the decomposable yard bags I can put out for weekly city pick up. As you can see in the photo, that little chain saw can do some mighty work. BTW, the battery did not run out while cutting down or chopping up everything in the picture.
A few weeks ago, a huge storm blew through here, knocking down tons of limbs from my veteran trees. My trusty little chain saw made the clean-up fun instead of an exhausting chore.
If you have trees or large shrubs, I highly recommend a tiny chain saw. I imagine products vary, so in a completely unsolicited and uncompensated 
endorsement, here’s the one I bought, in case you are in the market. I bought the MKSENSE Mini Chainsaw, 4-Inch Electric Chainsaw Handheld Mini Pruning Shears Chainsaw for Tree Trimming Wood Cutting (2 Battery & 2 Chain &1 Box & Installation Tool) on Amazon.
Here’s to happy gardening with your mini-chainsaw.
