Lost in a sea of better known competition, the T10 Multitool by IDL Tools is a lesser known, but not lesser quality, contender.
The tool is all stainless steel construction, and held together with peened pins. The tool is 2" (51mm) long, 1 1/8" (29mm) wide, and an incredibly thin 5/16" (including pins. Without them, it's only 1/4" (6.5mm) thick. Weight is 1.7 oz (49g).
Here is the tool folded up.

It wasn't a planned purchase. I didn't even know it existed until I saw it in the display case at the Brigade Quartermaster on Ft. Stewart more than a year and a half ago. I liked the idea of having a small tool to carry on my keys, since the Gerber MP600 I was issued was too big and bulky to carry out of uniform. I purchased the tool for around $20. It has been on my keys ever since.

I have been aware of the Gerber Curve for quite some time now and was attracted to it for it’s organic shape, locking implements and minuscule size. I was just never able to justify paying $10 for the tool and $5 shipping. I found one while browsing in a Dick’s store about two weeks ago. Its the first time I’ve seen one in a store, and seeing it in person made me want it even more. I ignored the $15 price and bought it.

An often-overlooked entry into the keychain size MT market is the SOG Crosscut. I was talked into buying one from ‘Sharper Image’ or some such mall shop many years ago, and as overpriced as it was, I would have paid it again. The original Crosscut was an absolutely excellent tool. It has been replaced by the Crosscut 2.0, with only a few refinements, and a fairly major drop in build quality since production switched from the United States to China. While it’s not what it used to be, it’s still an excellent option for keychain carry.

These tools are a bit like fraternal twins, at first glance they look nearly identical however they are very capable individuals. Both tools are lower cost options in the full size category from Leatherman but don’t be misled by cost alone as they are no Ed McMahon to Johnny Carson or Ethel to Lucy. The Wingman is a trusted friend and companion and the Sidekick a competent multitool ready for a task. I feel Leatherman nailed these offerings, though not just for the budget minded consumer but for anyone looking for a tool to do exactly what it was designed to do, which is perform.
What kind of people would write collect and review multitools? Quite simple really- we are designers and do-ers, outdoors types and indoor types, mechanics, doctors, problem solvers and problem makers. As such, we have, as a world spanning community, put every type, size and version of multitool, multifunction knife, pocket knife and all related products to every test we could manage in as many places and environments as there are.
