Measure a Knife Blade

Scott Feldstein

The definition of a legal knife blade can be different from state to state. For instance. the state of Texas said in an unpublished appeal (Perez v. State 1999 WL 521705) that a knife blade includes the sharpened and unsharpened parts of the blade above the knife handle. The American Knife and Tool Institute states that a knife blade should be measured from where the knife handle ends.
