I believe that the country folk don't keep a hoe around for gardening, it's for snake defense. It was always my grandpa's weapon of choice when he found a legless home invader that needed to be disposed of. I've always had the 'get it outside and let it live' mindset, but I'm a softy for critters and I'm not scared of them. I don't think I'd kill one unless it was venomous, but I don't like killing anything more than a bug. I'm no eco-hippy, I was just always the kid that made everything a pet, not prey.
Actually she grabbed our "back hoe".
Standard hoe that you put some heat on the neck and turn it where the blade is inline with the handle. You push it through the garden just under the surface to shear off the weeds.
Use one one time, and you will wonder why somebody didn't do this before. I'll take a pic of it tomorrow and post it.
