Anyone with any sort of knife collection probably has at least one they would consider "overkill," as in it's simply overmatched for all but the most extreme (and implausible) uses.

(Also inexplicably only fits people with small child-like hands which is me.)
What's your favorite "overkill" knife? (Pics a plus.)
