@gungasnake,
That "table 12" from the FBI can be summarized as follows:
……………..................…...Murders
...Percent of Total Murders
Total murders*
…............…15,070
....100%
Murders by firearms
…......…11,004
.....73%
Of which:
….Handguns
…....... 7,105
………………...Rifles
…............… 374
………………...Shotguns
….......... 262
………………...Type unknown
....3,263
Knives, cutting instruments
..1,604
....11%
Other weapons
.....................1,806
....12%
Hands, fists, feet, etc.**
..........656
.....4%
* Total number of murders for which supplemental homicide data were received.
** Pushed is included in hands, fists, feet, etc.

Therefore: 1) firearms account for 73% of all murders in the US, while knives only feature in 11% of homicides; 2) the breakdown by type of firearms includes a large number of "type unknown", therefore no precise estimate can be given of how dangerous are handguns, riffles or other firearm types; 3) this said, handguns appears to be the type of firearms most often used to kill.
There's a strong case to ban firearms, therefore, but the data is not precise enough to pinpoint the most dangerous types of firearms.
