Multitools聽can save you from gear malfunctions in the wilderness or if you need to tinker with your toilet鈥攁nd everything in between. The right one should be as at home in a pair of jeans as it is in聽a mountaineering pack. And because it might spend a ton of time with you in many different places, it鈥檚 important to pick the right one. I put four of my favorites in a head-to-head test to make your choice easier.
The Test

- Pocket Comfort: Each one lived in both my right and left front pockets of my most worn jeans for a聽day (two days total).
- Tool Deployment: I opened each instrument聽on every multitool聽a dozen times. During my garage and shed restructuring project, I deployed each instrument while my hands were full. I also buried all of these tools in dirt and then used them, because I can never keep a multitool clean in the field.
- Tool Efficacy: I used these tools for serious garage, side-yard, and shed-building projects. I cut up dozens of boxes, took apart a shoddily constructed shelving-and-workbench combo, and tinkered with additional shelving (Gorilla racks and others) in my garage. I also worked on all three of my bikes (mountain, road, and electric cargo).
The Results

The Winner: Leatherman Free P4 ($140)
Pocket Comfort: 5
Tool Deployment: 5
Tool Efficacy: 4
The 聽took the win because the 21-implement multitool was brilliantly designed, with exceptionally rich features, a sleek build, and simple functionality. Usually companies sacrifice one or more of those positive attributes in service of the others, but the P4聽rose to the top in all three categories. Credit a聽magnetic opening-and-closing system that makes all 21 instruments usable with just one hand. The ability to utilize any tool in the P4 while holding up something that would crush me if I let go was helpful during my garage and shed cleans. The two knives were among the sharpest in the test, and I was able to efficiently rip through wood with the saw. I鈥檓 a strong believer that more implements don鈥檛 make a better multitool, but I was impressed by the sheer number in聽the P4 and how streamlined it聽was. However, its Phillips-head screwdriver was among the worst in the test, so beware of that.聽But the smart design and usability of the other 20 tools earned the P4 a deserving victory.

Best Tools: CRKT Technician ($65)
Pocket Comfort: 3
Tool Deployment: 3
Tool Efficacy: 5
While 聽had only eight tools (the fewest in this test), each was extremely useful. With its聽4.5-inch closed length, 11.8-ounce weight, and beefy width, it tied for most onerous in my pocket, but if you want the most effective tool set, maybe you鈥檒l stash聽the Technician in work pants and not skinny jeans. Even though the quarter-inch bit driver was about a half inch shorter than the Center Drive Plus (below), I never rapped my knuckles while unscrewing the shelves in my shed, and it had plenty of torque. I liked the texture of the M10 handle, which allowed my sweaty hands to get purchase on the tool and made聽it far more effective. The blade was excellent for breaking down boxes, but I was a little nervous taking on larger cutting projects with the 2.58-inch blade, because it was extremely sharp and didn鈥檛 lock. The telescoping magnetic pick-up tool was the surprise MVP for me;聽I was much more efficient when I could grab screws, nuts, and bolts that I dropped with the extended magnet instead of fully bending over.

Best for Simple Use: Gerber Center Drive Plus ($125)
Pocket Comfort: 3
Tool Deployment: 4
Tool Efficacy: 4
The 聽really hit a sweet spot in terms of extreme tool capability and ease of use. The pliers and the screwdriver were the simplest to operate with one hand聽and were beasts while wrenching on drawers and bikes. The screwdriver is particularly impressive:聽it spans the entire length of the handle (rather than swiveling out of the interior of the tool, like the others on this list), delivering聽maximum torque. Using it feels almost identical to the screwdriver that lives in my tool kit. At 4.7 inches long (closed) and weighing聽9.5 ounces, the 16-tool Center Drive was bulky in my pocket and would only make sense as an everyday carry if worn on a belt carrier鈥攕omething I just can鈥檛 bring myself to do. Overall, if you mainly use the needle-nose pliers and screwdriver, the mix of burliness and usability on those two tools makes this your best bet.

Best Buy: SOG PowerPlay Hex ($46)
Pocket Comfort: 4
Tool Deployment: 3
Tool Efficacy: 3
SOG makes some of my favorite EDC knives,聽and that pedigree stood out in . It featured two of the top blades in this test: a straightedge that absolutely shredded cardboard and a serrated one that put up a fight against the P4鈥檚 saw tool while cutting wood. The small, streamlined unit had a great overall aesthetic, with the exposed opening-and-closing cog catching my attention right out of the box. The Hex聽did, unfortunately, get very difficult to use after I covered it聽in dirt. Knives aside, the tool set鈥檚 challenges outweighed its functionality鈥攊t had wimpy needle-nose pliers and an inefficient screwdriver. I was, however, extremely impressed that the Hex came close to the others in effectiveness, despite being half the price of the nearest competitor (and nearly a third of the most expensive).
