It's an Easy Choice
I am a Medical Imaging service engineer. I've reduced my 50 lb. tool bag down to my New Wave, a multi-meter, my laptop, and some custom made attachments. A light weight pack for a 63 year old man. I occasionally have to return to my car for a special tool, but not often. Also, I've been collecting knives since I was 5 years old. I have over 500. What do I carry in my survival bag? Yep, a Leatherman!
Our most popular model, with outside-accessible blades, bit driver, scissors, and wire cutters, all in a 100% stainless steel body.
