maybe I missed something here but there is a lot of talk about healing up etc. I think that is the wrong mindset. I hunt to kill not mame.

another thought, after the razor sharp blade goes thru the hide, sub q, muscle and into rib bones, chances are that blade isn't razor sharp any more. I think that the razor sharp blades curl the edge after going thru ribs. with this in mind I prefer the blade that when ran over my finger nail will catch as drug across it. it is not a razor sharp edge but a good edge that can be maintained b/c the outermost edge of the blade is not featheredso much that it curls after running across bone.

as far as surgeons using scalpels, yep they reuse them the whole case until they get dulled. generally one blade for the skin and one for the inside of the incision as to keep from spreading the organisms on the skin in the incision. not all surgeons use a different blade for both but many I know use this practice. I don't know any surgeons that whacks away on bones with blades either.

this is just food for thought and my 2 cents. I like sharp bh's but I don't think the razorsharp ones are best. With this in mind, I am not saying shaving sharp is not good either b/c my bh's will still shave your arm but not the hair popping sharp. The reason is the angle is a little more steeper and the blade is not feathered out as much.

p.s that spiderco sharpener that Tonypreacher talks about is one of the best I owned for sharpening knifes, etc. in there video that comes with it describes the different type of blade angles and the uses for each. I gained a lot of insight watching it.
