  Missouri Case Law:
– “Knife which was 7 to 8 inches long with a 4 to 5 inch
   blade could be found to be a ‘dagger’ and thus a ‘deadly
   weapon’… (1982)
– “Information charging defendant with knowingly carrying a
   concealed weapon, a boot knife with a 4-1/2 inch blade,
   was sufficient to negative statutory exception to offense
   of unlawful use of weapon, providing that pocketknife with
   blade no more than 4 inches in length is not a knife,
   where defendant’s knife had a fixed double-edge blade that
   did not fold into handle.” (1982)
– “Evidence that knife defendant was carrying was a paring
   knife with a sharp point supported classification of knife
   as bladed hand instrument readily capable of inflicting
   serious physical injury or death by cutting or stabbing
   person within meaning of… 571.010, and thus, issue of
   whether defendant carried a ‘knife’ was properly submitted
   to jury.” (1986)
– “State trial court’s admission of knife in prosecution…
   over objection that it did not meet the statutory
   definition of ‘knife’ did not violate any constitutional
   right or deny due process…” (1992)
– “Butterknife used by defendant in burglary and attempted
   forcible sodomy was ‘dangerous instrument’…” (1993)
– “… steak knife was ‘dangerous instrument’ as employed by
   defendant…” (1993)
– “This section prohibiting carrying concealed weapon
   includes ‘straight razor’…” (1977)
