i was gonna just pm cliff on this but figured most everyone here would be interested in his response....so....


Cliff,
whenever i hear people discuss modifing a blade they always say that they never let the blade get more than warm to the touch.... to avoid damaging the heat treat,


ok.... alot of us carry our busse knives in our cars, in our tool boxes etc.... and if i leave my black crinkle coat blade sitting on my front seat it sure as hell gets hotter than 'warm to the touch' is this affecting the heat treatment?

and if so doesnt that imply a fault in the heat treatment?

curious?
 
On a 100 degree day, in direct sunlight, the interior of a car with the windows rolled up will reach a maximum temp of somewhere between 140-150 degrees. While dangerous to humans and pets, I can't imagine such a temperature would have any effect on the temper of steel whatsoever. I'm no metallurgist, but I don't think you start to see a heat effect until at least 300 degrees or more.

yes, you are correct, and you won't be affecting INFI at temps far above that. The problem is determining the temp, which is nearly impossible. So better safe than sorry in most cases.
 
a small infared thermometer will give you the temp, they run anywhere from $35 to $150

yes, the problem is that when you are grinding, temps climb much faster than you can read. It's better to just keep it cool and not worry about it.

Not only that, but the temp of the area of the steel that is being ground can get much hotter quicker than the part of the steel you're holding. So the rule about not letting the steel get hotter than you can hold is a nice, conservative rule of thumb. It just doesn't mean that getting steel hot to the touch is itself damaging to the temper.
 
Does Cliff actually post over here? If so, I've never seen it.

I know he owns a fabled toothpick of a BM and that he appreciates Busse blades, but I think he's too busy impressing the neophytes over in General and/or Wilderness.
 
when he gets over here to read, he will post, but he usually stays in the general and review forums. After all, he only owns one Busse knife and the only knife he will not let go of, trust me I tried to take it from him.:eek:
