Michael, you can't get a campfire burn on a cloudy day because the sun's light is made diffuse by the clouds, which means the light scatters & travels in all sorts of different directions. In order to get a burn through focusing sunlight (via magnifying glass, or in this case a polished parabolic surface on a knife), the rays of light must first be traveling parallel to each other -- as they do when there are no clouds between the sun & the focusing surface. A sunburn is an entirely different mechanism, & the diffuse UV rays can still cause a sunburn on the skin, because this requires much less energy. If they required the same amount of energy, you wouldn't get a sunburn even on sunny days -- unless someone was focusing sunlight on you with a magnifying glass or highly polished parabolic surface. As far as the solar knife goes, that handle is made of aluminum, which I doubt would be very comfortable, especially in cold weather, & the sheath they provide wouldn't give much protection to that polished surface -- even the rivet of the retention strap would likely scratch it, thus reducing its efficacy. It's an interesting concept, but the execution leaves me preferring a much cheaper magnifying glass or more flexible fresnel lens in addition to whatever knife I would be carrying (the 420 blade & sheath are not the focus of this knife, the parabolic mirror handle is).

I would like to see the "Solar Knife" in action. The parabolic reflective surface of one side of the grip is a novel idea, instead of using some sort of magnifying lens which might get broken. About that cloudy day....duh...just use your tactical LED flashlight to shine on the knife?( I told you I was funny! ) Maybe I need to refresh my physics knowledge, or lack thereof. But now I'm wondering if you can somehow harness the sun's ultraviolet rays even on a cloudy day....you can get a sunburn on a cloudy day. Why not a campfire burn?
