Remember what I said the other day, about how the best pocket knife is the one you carry? I meant it. If you cannot or will not carry a pocket knife or multi-tool, there are still quite a few keychain-sized multi-tools available. Any knife is (usually) better than no knife.
The Opinel keychain is 1-7/8″ when closed and 3-1/8″ open with the 1-5/16″ blade fully extended. The blade is made from stainless steel, and the handle is beechwood. Normally sub-$10 knives make me wary, but not this one.
While I do like keychain tools that have industrial-looking or mass-appeal designs, the Opinel knife really caught my eye as something different. Maybe it’s the wood handle. Yes, it’s definitely the wood handle.
There are a number of other mini knife options as well. At first thought the SOG Micron knife comes to mind, but it’s a little bit too small and flat, and so I regularly misplace it. I’m still not over SOG’s lousy customer service incident.
