For about 12 years, I carried a rolling case with 9 separate corded tools to every small repair job across my rental properties: a jigsaw, a detail sander, a mini circular saw, a grout removal tool, and a handful of others I only used a handful of times a year. Two years ago I sold most of that case at a local recycle shop for around 8,000 yen combined and replaced it with one oscillating multi-tool. That single swap has saved me an estimated 40 minutes per repair visit, just in setup and teardown time, and I have not missed a single one of those old tools since.
This is not a review of one brand. It is what changed for me after 15 years of self-managing 9 rental units, and why I now reach for the multi-tool before almost anything else in the truck.
The Problem With My Old Toolbox

My most-used tool. If you own one power tool, make it this.
Small repair jobs are rarely one task. A tenant reports a stuck window, and by the time I am on site I am also trimming a swollen door bottom, cutting out a rotted patch of subfloor edge, and scraping old caulk out of a tub surround. With single-purpose tools, that meant unpacking 3 or 4 different machines, running 3 or 4 different power cords, and swapping blades or bits between each one. On a tight schedule with 2 or 3 units to visit in a day, that setup time added up to real money. I once tracked it for a month: across 18 visits, I spent roughly 6 hours just switching tools and cords.
What Finally Changed My Mind

Power Tool Combo Kit (18V)

The tipping point was a single afternoon at one of my older properties, a 1988-built apartment where I was patching a water-damaged section of vinyl flooring, trimming a door for new carpet, and removing a rusted-in screw from a window latch, all in the same 90-minute visit. I had brought my usual case, but a neighbor happened to be using an oscillating multi-tool on his fence and let me try it on the door trim. It took about 4 minutes to do what normally took me 15 with a hand plane and sandpaper. I bought my own within the week for just under 12,000 yen, blades included.
The Jobs Where the Multi-Tool Earns Its Keep
After two years of near-daily use, here is where it consistently beats a dedicated tool for the kind of small, unpredictable repairs landlords deal with:
- Trimming swollen door bottoms and edges without removing the door from its hinges
- Cutting out rotted drywall or subfloor sections for a clean patch, especially in corners a jigsaw cannot reach
- Scraping old silicone caulk and adhesive residue from tile and tub surrounds
- Flush-cutting protruding nails or screws in tight spaces, like behind a baseboard
- Sanding small detail areas where a full-size sander would gouge the surrounding surface
- Cutting a clean opening for a new electrical box in existing drywall
What ties all of these together is that they are 5-minute-or-less tasks buried inside a longer repair. A dedicated tool for each one would sit unused for months between jobs, and I would still need to dig it out of storage and remember where I put the right blade.
What It Cannot Replace

Tool Storage & Workshop Organizer
A well-organized toolbox saves 20 minutes on every job. Multiply that by 100 repairs.
I want to be honest about the limits, because I see plenty of people online treating a multi-tool as a total toolbox replacement, and that is not realistic. It is slow and tiring for anything resembling a long, straight cut; my circular saw still handles all full sheet or full board cuts. It also does not have the torque for demolition work like breaking up old tile, and it struggles with material thicker than about 20mm in a single pass. For those jobs I still reach for the specific tool built for the task. The multi-tool is a specialist in short, awkward, detail-oriented cuts, not a replacement for your main saw.
Picking Blades and Attachments Without Overspending
The tool itself is only half the cost. Blades wear out fast if you use cheap ones on anything with embedded nails or old adhesive, and I learned this the expensive way after burning through 6 bi-metal blades in my first 3 months. My current approach, after some trial and error:
- Buy a mixed starter pack rather than single blades; mine came with 13 pieces for about 3,500 yen and covered 90% of what I needed
- Keep at least one carbide-grit blade on hand specifically for grout and tile adhesive, since standard wood blades dull in one use on that material
- Stick to one brand’s blade mounting system once you commit to a tool, since the universal adapters I tried added noticeable vibration
- Replace a blade the moment it starts to smoke or bind rather than pushing it through one more cut, which is what actually kills them early
Was It Worth the Money
Two years in, my honest tally is this: I spent about 12,000 yen on the tool and roughly 15,000 yen total on blades and attachments since, against maybe 70,000 yen worth of single-purpose tools I no longer carry or maintain. More importantly, I estimate it has shaved close to 25 hours off my repair schedule this year alone, time I have put toward actual renovation work that brings in rent increases rather than toward digging through a toolbox. For a landlord doing their own maintenance across multiple units, that time savings matters more than the yen saved on tools.
That is the approach I use across all 9 of my properties now: one multi-tool on the truck at all times, and the single-purpose tools reserved for the handful of jobs that genuinely need them.
