I have a SAK alox bantam and the blade is quite exactly 2.5". That little knife is actually quite good, has 3.3" scales and looks as peaceful as a butterfly.
However, all daily chores can be done with it quite easily.
Gotta put in a vote for the Kizer Shard. Bought this knife just because I liked the black micarta and have been unexpectedly surprised by how much I like it. As a package opener/small task knife, it's awesome. The ergos are great, carries deep, feels solid, and flies open. And the micarta is every bit as nice in person as the photos. 2.25" blade.
