I don't think it's stupid or silly at all- it's a valid question.

Personally, I would get a larger knife to put in with your tools in the company vehicle, since firearms are against company policy. I think the bigger question is this: if you do clip a deer, for example, how far into the scrub or woods will you follow it? Do you have a powerful flashlight? If your jobs take you off the beaten path at night, will you be following the wounded animal's trail into the woods?
