Well, if we're including nearby knives, add S -1 and A-1 Fallkniven and a pair of machetes, a Brazilian one with 18" blade and a Salvadoran one with a 12" blade. Quite handy.

I just rotated a Buck Model 105 like that seen above, and have a Buck Model 119 (75th year version) in reserve.

My choice of a pistol for office defense is a Beretta M-92FS. Loaded with Gold Dot or Federal HST 124 grain Plus P ammo.
