Some of them will be single-use items that you'll store in your garage or toolshed for decades like a museum exhibit. But sometimes even these tools can surprise you by being way more useful than you might initially imagine.For me, the mini chainsaw was one of those tools. This one, specifically (I considered others, but I really wanted a one-handed, cordless option because I live in a small, urban house, not a sprawling farm that runs on firewood and steam). I bought it specifically for landscaping/pruning chores, but it’s quickly proven to be one of the most useful little tools I own—so useful, in fact, that I think every DIYer should have one. Here are just a few ways I put it to good use.

I love my neighbors, and it’s not a point of conflict, but if I don’t stay on top of that situation, my whole house will be enveloped by a creeping vine that’s been colonizing their yrad so long it’s almost structural, and I’d never see the sun again due to the encroaching branches of their backyard trees. The mini chainsaw is perfect for this work. It slices right through the (surprisingly thick and robust) vines, as well as the tree branches. As it's a one-handed tool, I can safely wield it from a ladder without risking my fingers (or more critical body parts).Cutting through more than just branchesIf you think you only use chainsaws on lumber—cutting firewood, or clearing fallen trees—you’re wrong. What’s great about a chainsaw in general is that it slices through dense, thick material like that with ease. I’ve used mine to cut through stuff like PVC when doing minor plumbing work around the house, and it worked a charm.It’s also great for quick cuts on wood. While I wouldn’t use a chainsaw in place of a circular saw or table saw for precision cuts, it’s been a real time-saver to just trim a bit here and there, especially after I’ve secured a 2x4 in place with screws only to realize I miscalculated the initial cut by a quarter inch. The mini chainsaw just lops off the excess without drama.Some folks online claim they’ve used mini chainsaws to make quick cuts in drywall, but I’m not sure I’m going to try that. I'm sure it works, but it sure seems like unnecessary overkill.Demo workEvery DIY project starts with demo and removal, and a mini chainsaw has become an essential tool. For example, when I re-did a deck recently, I had to pull up and haul off all the old planks and structure. The mini chainsaw made it easy to cut everything down to a more manageable size so I wasn’t navigating 10-foot boards through the house. It was a fast, easy way to reduce a lot of cumbersome junk and prevent a bit of the inevitable damage I caused (to my back as well as my house).Having fun while DIYingThis isn't really a use-case, but it's worth mentioning all the same: mini chainsaws are fun to use. The ability to just press a button and slice away anything that’s irritating you is well worth the price all by itself. (If you're like me, the opportunity to make your own chainsaw noises while you use it is just an added, unnecessary bonus.)
