Yes it happens and it sucks ass when it does. Neverhad a bad cut in camp well not to bad at least until last years Elk hunt when my cousin and I were quartering up his 5x5, he cut his Hand bad, so i taped him up, loaded the quarters on the horses and hit the trail out. well wewoke up at 4:AMgrain bagged the horses had some oat meal and hit the trail by 5:AM.He cut himself at about 9:30am and we got to E.R. At about 4:00pm. They did a great job atGlenwood Springs Co. E.R. and wewere out of there at7:30stopped filled the gut, had two shots, two beers. Drove back to the horses andstarted up the trail at about 9:30 road into camp at 2:23am"thats good time in the dark on the mountain"

It happened again this yearto me, and yes it was dam scary crap to deal with. For the complete story and good Field med kit info

there is a new product called QR POWDER get it at cabela's
The claims are that it will " even stop the bleeding associate with complete transection of the FEMORAL ARTERY.....pretty heady stuff but I saw the actual video of a pig being used as a "patient" in a US army video where they transected his(pigs) femoral artery and it stopped the bleeding and saved his bacon er.... the patient...

It workes both by being positivley charged and cross binding with the negative charges of our red blood cells thus locking them together it also has a astringent characteristic that extracts the water and dehydrates the blood...

The femoral artery is the largest in the human body..and if this product(s) can stop that kind of bleeding it CAN save your life.Used in conjunction with a good pressure bandage it is something that doesnt take up much space but can be THE most important item in any back country first aid kit.

The other amazing property about these product(s) is it is completely reversable..once in a surgical situation and the appropriate sutures have been put in place and volume expanders and blood products have been given the surgeon can irrigate the "clot" made from these products and totally disolve the blockage and resume normal blood flow.....

Pretty cool stuff
I will have it on me at all times now even in my Truck
