Blood grooves???

Well we had the same discussion in the Austrian/German messerforum.net. My opinion was, that an blood groove has no effect. Look at a SOG Dessert Dagger for example.It has a bloodgroove. Ok and now tell me, how much blood is getting out of the body in this groove? You see, thats not very much in comparison of how many blood gets out of an stabbed organ. How also says, that the blood has to leave the body, theres enough space in the underbelly, were the blood can flow to.
Because of the vacuum. If the blade gets turned around in an 90° angle, then there won't be any vacuum and there flowes more blood out of the stab, than with such a tiny blood groove.
One of the forum members asked a firend, who is a doctor, and this guy told him, that my thoughts were right.

I hope that I could help with your problem.

Those were just theoretical thoughts, not that I ever had any cause to try out what I wrote here.
 
One thing; there will be no "vacuum" or "suction" created when you stab someone. Suction, technically, doesn't even exist. The only way you get "suction" is when fluid pressure on one side of something is higher than on the other, so it's more like "obstructed blowing."

If you stab someone, then the knife has fluids and tissues pressing on all sides of the blade (including _out_), while there's also _some_ air pressure pushing "in." Unless you're extremely far underwater or on a planet with a _really_ dense atmosphere, there won't be any "suction" effect with a normal knife.

Now, if you use a hollow stabbing implement that's filled with air and plugged on the end that isn't getting stabbed (like a sharpened pipe with one end plugged), _then_ you'll get suction, because of the air inside the thing.
 
Are you kidding me! Is this for real! Vacuum's from stabbing. Next year when I get another deer, I'll stab it and leave an update. Or better yet wait for some road kill. I'll go for the ribs though cause I don't want to ruin the meat. ;)
 
Do you mean me with the vacuum- thing? I never claimed that there would be an vacuum, that was baumr how brought this into discussion (and the guy in the German forum thougt this too). Could be that there is a vacuum or not, but I just said, that it would be better to turn the blade around its axis than to have a blood groove.

@blackboogers: Would be great if you'd do this, so that everybody knows! Thanx
 
Vacum Smacrum... My old Regimental Sergeant Major in the Royal Canadian Regiment had this to say about bayonets getting stuck in the enemy. First immediate action drill...Stick it in, twist it, pull it out. Second immediate action drill if it sticks ...Pull the trigger and blow the slant eyed commie scumbag back accross the Yaloo River.
I never had the balls to to ask him Why, if I had a round left in my rifle, would I have ever let the scumbag get close enough to me that I had to resort to using the bayonet in the first place?
Please forgive the politically incorrect physical description he used. It came from a man who left a lot of his own blood and a lot of good friends in Korea in the 50's and in no way is meant by me to denegrate any ethnic group. Now as far as the commie scumbag part goes I agree.

try getting the fuller stuck beween some bones in a rib cage and get it back out, it is made that way to lighten the load,
and it may stick in a bit easyer.
