Defendant was convicted for exhibiting a small pocketknife in a threatening manner. On appeal, he argued that his 4 inch pocketknife could not be a basis for a weapons conviction since Chapter 571 excluded 4 inch pocketknives from the statutory definition of “knife”. The appeals court affirmed the conviction stating that the intent of excluding small pocketknives was to permit the concealed carrying of them and was not a declaration that suck knives are incapable of lethal force.
